AuraHealth
Live
v3.16.2
· Health & wellbeing
A private health check-in on your phone: it reads your lab reports, measures your pulse and more with the camera and sensors, and coaches you, with everything kept encrypted on the device.
The web app opens in any browser. The Android app is not on Google Play: download the .apk (53 MB) and allow the install when your phone asks.
What it does, features and use cases
AuraHealth is a free health check-in that lives on your phone. It reads your own lab reports, keeps records for you and the people you care for, and takes real measurements with the phone's camera, microphone and motion sensors: fingertip and face pulse, heart-rate variability, breathing, voice, hand tremor, walking, balance, reaction time, hearing and near vision. Every scan checks it is measuring the right thing before it reports a number.
A team of agents on the phone turns this into help: a weekly coaching plan built from your own numbers, medicine checks against your lab results, food verdicts from a barcode or label, symptom signposting to 999 and 111, appointments and re-test reminders, and a summary to take to your doctor. A safety agent reviews every message, every network call needs your consent, and everything the agents do goes in a tamper-evident audit log.
Everything is analysed and stored on the device and sealed with AES-256 under a key kept by the phone's secure hardware. There is no account, no ads, no tracking and no server holding your health data. It works in English and Hindi, with UK, US and India health packs. In the app, More → Try each feature plays guided demos with a sample family.
AuraHealth gives wellness information only. It is not a medical device, and camera, voice and motion results are estimates.
Features
- Reads lab reports from a photo, PDF or health-record export: 45+ markers, unit conversion, your lab's own ranges kept
- Fingertip and face pulse, heart-rate variability and breathing from the camera, with a check that a real finger or a live face is in view

- Food verdicts from a barcode or label: UK traffic lights, sugar in teaspoons, ultra-processing, allergens and alerts for your own conditions
- Weekly coaching plan built from your own numbers, with every item explained
- Symptom signposting to 999, 111 and Samaritans, never a diagnosis
- Appointments, re-test reminders and a doctor summary with suggested questions
- On-device AI that reads photos and speech, including Indian languages, and searches your records by meaning, with no API key
- Places to be active nearby from OpenStreetMap, with your location rounded to about 1 km
- Everything sealed on the device (AES-256-GCM, key in the phone's secure hardware), with a hash-chained audit log

FaunaVox
Live
v1.2.2
· Pets & wildlife
Hear what animals mean: your pet's moods and the wild animals calling around you, recognised on your phone.
The web app is open to everyone. The Android app is in a closed test on Google Play: join with the test link using an invited Google account, then install it from Google Play.
What it does, features and use cases
FaunaVox listens to animal sounds and tells you what they likely mean: your dog's whine, your cat's yowl, the bird in the garden or the deer barking in the forest. Recognition runs on the phone or in the browser, so sounds are never uploaded.
It has two modes. Pet Mode helps owners understand their own pets: it learns each pet's voice, keeps a mood diary and a health log for the vet, and can watch a pet left home alone. Wild Mode names animals by their calls, warns about dangerous animals and reads the forest's alarm calls, with stations and alert groups for people who live or work near wildlife.
Every result says how sure FaunaVox is and why. Meanings come from animal-behaviour research and are shown as likely moods, never word-for-word translations, and the accuracy for every animal is published. There is no account, no ads and no tracking. It works in 9 languages: English, Hindi, Marathi, Bengali, Tamil, Telugu, Kannada, Malayalam and Spanish.
Features
- Recognises dogs, cats, parrots, horses, rabbits, guinea pigs and farm animals, and the kind of call: bark, whine, growl, meow, purr, hiss and more
- Teach it your own pet's sounds in seconds; it also learns from your "Was this right?" taps
- Tells several pets apart by voice
- "Unusual tonight" alerts when a pet makes more sounds, or more distress, than its own normal
- Sleeping breath counter and a health log for the vet: cough, sneeze, reverse sneeze, retch and wheeze
- Body language from what you see or a photo, read together with the sound
- Home-alone monitor: a spare phone alerts yours, including smoke alarms and breaking glass, end-to-end encrypted
- Wild Mode names 114 animals by sound, with exact bird and wildlife species from Google's Perch model
- Danger alerts with safety steps for snakes, big cats and other risky animals
- Forest alarm meter, alert groups on a map and a community map of what stations hear
- Backyard, coop-guard and village-sentinel stations from an old phone
- Animal library of 115 animals and 249 real calls, a kids' quiz and a pet-mood quiz
- Works offline once the recognition pack is downloaded; backups are locked with a password
- Large text, vibration and screen-flash alerts for deaf and hard-of-hearing owners
Use cases
- A dog owner wants to know whether the whining at the door means anxiety, a need to go out, or a bid for attention
- Someone leaves a pet home alone and wants an alert on their own phone if it is distressed or a smoke alarm goes off
- A pet owner keeps a record of coughs and sleeping breathing rate to show the vet
- A hiker or birder wants to know which animal is calling, and whether the call is a warning
- Villagers and forest workers near tiger or leopard country get early warning when the forest's animals raise the alarm
- A family learns animal sounds in their own language with the animal library and the kids' quiz
- A vet clinic puts up the FaunaVox poster so owners can record symptoms at home between visits

FinancialScan
In testing
v1.0.0
· Banking & fraud prevention
Fraud prevention for Indian banks: catches mule accounts and deepfakes at account opening, guards payments, and runs RBI's fraud compensation claims.
The demo bank website and the feature guide are open to everyone. The bank staff console needs a demo sign-in: ask the owner. The links change if the demo server restarts.
What it does, features and use cases
FinancialScan is a fraud prevention and detection platform for Indian banks, built with co-operative, regional rural and small finance banks in mind. It is made of separate features: each bank subscribes only to the ones it wants, and features share data only when the bank allows it. Every threshold, rule and piece of wording can be changed from the console, with four-eyes approval.
At account opening it checks the applicant's identity (Aadhaar QR and Aadhaar-app credentials, PAN), looks for deepfaked selfies, videos and voices, risky phones and SIMs, and the signs of a mule account, then gives a GREEN, AMBER, RED or BLOCK decision with its reasons. Risky applications go to a reviewer from another branch, who gets a numbered case file and drafts of the customer notice, police report and STR. A guided interview in the applicant's language covers branch, business-correspondent and online openings.
After opening, it watches the first 90 days for accounts that are rented or sold, checks a change of mobile, SIM or nominee before it is applied, warns customers at the moment they press Pay, manages debit holds under RBI's procedure, and runs RBI's compensation framework for small digital frauds (from 1 January 2027), including signed claims between banks. Small banks can share mule identifiers with each other privately. It also defends against bots and AI agents, and lets a customer give an AI agent strictly limited permission to pay (Google's AP2 and Mastercard's Verifiable Intent).
Every decision gets a receipt signed with a classical and a post-quantum key, which police or auditors can check without an account at the bank. The deepfake models run on the bank's own servers, and nothing goes to a hosted AI unless the bank switches it on. A privacy console covers India's DPDP Act. It is tested by 65 scripted personas (306 of 306 checks passed) and a demo bank that walks through the whole flow with sample applicants.
Features
- Identity checks: Aadhaar Secure QR and Aadhaar-app credentials verified against UIDAI, PAN status and name match, and business checks (GSTIN, Udyam, MCA)
- Deepfake and forgery checks on selfies, ID images, video, voice and edited income-proof PDFs, and the same face or file reused under other names
- Phone, SIM and network risk from the bank's Android and iPhone apps: Play Integrity, App Attest, a call in progress, remote-access apps
- Mule-account signals from Account Aggregator statements and the DoT, I4C, MuleHunter and RBI DPIP lists
- GREEN / AMBER / RED / BLOCK decisions with reasons, and a second-level review by a reviewer from another branch
- Investigation helper: a numbered case file, and drafts of the customer notice, police report and STR where every sentence cites its evidence
- Guided interview in the applicant's language, with follow-up questions, a proof-of-presence step and checks for a second voice or a changed person
- First-90-day watch for rented or sold accounts, and a guard on changes of mobile, SIM, e-mail, device or nominee
- Payment-moment guard: allow, warn, pause or stop as the customer presses Pay, with the message in their language
- Debit holds under RBI's procedure, and RBI's compensation claims for small digital frauds with signed claims between banks
- A private cross-bank mule consortium (private set intersection) set up for small banks
- Bot and AI-agent defence, and payment permissions for AI agents within exact limits (AP2, Verifiable Intent)
- Passkey approvals bound to the exact action, and receipts signed with Ed25519 and post-quantum ML-DSA-65
- Four-eyes changes to every rule, a DPDP privacy console, SIEM export and a model-risk pack for RBI
Use cases
- A co-operative bank's branch opens a savings account and wants to know whether the applicant is a mule recruited by cyber fraudsters
- A business correspondent in a village opens accounts with a guided interview in the customer's language
- A reviewer at another branch decides a risky application with all the evidence in one case file and the police report and STR already drafted
- A customer about to pay a scammer while on a call gets a warning in their language before the money leaves
- A fraudster with a new SIM asks to change the registered mobile; the change is held and confirmed on the number already on file
- After a fraud, the victim's bank works out RBI's compensation split and asks the receiving banks for their shares in signed messages
- Small banks share mule identifiers with each other without revealing their customers
- A customer lets an AI shopping agent pay within strict limits, and the bank checks every payment against them
- Police or an auditor check a signed decision receipt without an account at the bank

FlowIQ
In testing
v1.0.0
· Cameras & business analytics
Turns a small business's existing cameras into honest numbers on customers, waits, service and safety, on a local box that says when it cannot see.
Not available to try yet: a private build, tested on live public cameras, and its test server is switched off for now. Not for sale.
What it does, features and use cases
FlowIQ turns a small business's existing CCTV cameras into numbers the owner can act on: how many people came in, how long they waited, who was served and who walked out, the busiest hours, and how the staff's time is spent. It runs on a small computer on the premises, works with no internet connection, and video stays on site by default.
Nothing has to be set up for each venue. It learns each venue's own normal from how the room is used: which people are staff and which are customers, where the waiting area and service points are, when the venue is open, and what an unusual queue or wait looks like there. Zones can also be drawn on the camera picture: a waiting area, the service chairs, or a mirror, so reflections are not counted as people.
Every number says what it rests on, and when the camera cannot see something, FlowIQ says so instead of showing a zero. A salon whose door is out of shot is told its waits cannot be measured, not that nobody waited. Safety alerts for fire and smoke, falls, guns and knives come with a clip and a signed, tamper-evident evidence record, an incident report for an insurer, and Content Credentials on the clip.
It can also run a home or small building: Home Assistant and Zigbee devices, rooms that combine cameras with presence sensors, and rules such as "turn the heater off when the room has been empty for 15 minutes", with electricity prices from a flat rate, Octopus Agile or Home Assistant. A voice or text command can never unlock a door, open a cover or disarm the alarm.
It has been tested on live public cameras in salons, barbershops, pizza kitchens, a car workshop and a hotel square. A small two-core server handles about two cameras. Theft detection is not claimed. It is a private project and is not for sale.
Features
- Works with existing IP and CCTV cameras; checks a camera's feed before it is added and suggests its settings
- Counts people and follows each visit: arrival, waiting, service, and whether they were served, left unserved or only browsed
- Learns which people are staff and which are customers from how they behave, with no enrolment, and says why
- Waits, service times, walkouts, footfall and busiest hours, on the venue's own clock
- Learns each venue's room layout, opening hours and normal levels, and alerts only when something is unusual for that venue
- Zones drawn on the camera picture: waiting area, service points, and mirrors so reflections are not counted
- Safety alerts for fire and smoke, falls, guns and knives, each with a clip
- Signed, tamper-evident evidence records, an incident report for insurers and Content Credentials (C2PA) on clips; a false alarm can be marked, and the correction is signed too
- Every figure says what it rests on and abstains when the camera cannot see, instead of showing zero
- Owner digest, a printable weekly report, recommendations priced with the owner's own figures, and an ask-a-question box
- Home mode: Home Assistant and Zigbee devices, rooms that combine cameras and presence sensors, and rules like "heater off when the room has been empty for 15 minutes"
- Electricity prices from a flat rate, Octopus Agile or Home Assistant, and energy use per appliance
- Phone notifications to the installed web app; voice and text commands can never unlock, open or disarm
- Runs on a small local computer with no internet; video stays on the premises by default
- Face matching off by default and decided per site; an EU AI Act pack keeps staff analytics off for EU sites until someone named signs off
Use cases
- A salon or barbershop owner sees how long clients wait, who walked out without being seen, and which hours are busiest
- A café or counter business finds when its queues peak and how long service takes
- A kitchen gets fire and safety alerts where everyone in view is staff, without being scored on customers it does not have
- A shop with a camera on the door counts its footfall hour by hour
- After an incident, an owner gives the insurer a signed incident report and a clip with Content Credentials, not just a video file
- A family has the heater and lights switch off when a room has been empty for a while, using the cameras and sensors they already have
- A home is armed and disarmed as the family leave and come back, using Home Assistant
- A public square or forecourt measures footfall and safety with no staff figures at all

HaggleHub
In testing
v2.1.0
· Shopping & marketplaces
Post what you want and the most you'll pay; local shops compete to sell it to you, with real online prices alongside to compare.
Open web demo, no sign-up. Requests and bids are kept in your own browser, and the competing shops are bots. The free server can take about a minute to wake up.
What it does, features and use cases
HaggleHub turns shopping around. A buyer posts what they want, from a laptop or a pair of trainers to a watch, an appliance or a trip, with the most they will pay and how long the request stays open. Verified local shops then compete for the sale.
Shops never see the buyer's budget unless the buyer chooses to share it. They see the lowest bid so far and can lower their price to beat it, so the price keeps falling until no shop can go lower. The buyer can counter-offer on any bid, and the shop accepts or comes back with its best price. Shops only see requests in the categories they are approved for, and shops rated under 4.0★ are blocked until reviewed.
Next to the shop bids it shows real online prices: eBay, Best Buy and Sovrn Commerce for products, and Duffel and Aviasales for flights, once their API keys are added. Without a key it shows plain search links and never invents a price. A watcher re-checks the prices every 15 minutes while the page is open and alerts when one is at or under the budget. The buyer pays the chosen shop directly; HaggleHub never holds the money.
This is a working prototype: requests and bids are stored in the buyer's own browser, the competing shops are bots that price from a catalog of store prices, and shop verification is simulated. The web demo has no price keys connected yet, so it shows search links instead of online prices. It is tested by 10 buyer and 5 shop personas run against the real auction code (71 of 71 checks passed) and 21 checks of the price sources.
Features
- Post a request with your budget and how long it stays open: 24 hours, 48 hours, 3 days or 7 days
- Budget hidden from shops by default; you can choose to show it
- Reverse auction: shops see the lowest bid and undercut it, down to their own lowest price
- Outbid shops get a "Lower price" button and see where they rank
- Counter-offer on any bid; the shop accepts or comes back with its best price
- Real online prices from eBay, Best Buy and Sovrn Commerce, and airline fares from Duffel and Aviasales, once their keys are added
- Plain search links instead of prices when no price source is connected, never an invented price
- Price-drop watcher: re-checks every 15 minutes while open and alerts when a price meets your budget
- Affiliate links on eBay, Sovrn and Aviasales prices, marked as such
- Shops only see requests in their approved categories; shops rated under 4.0★ are blocked until reviewed
- Flight requests ask for airports, dates, passengers and bags, priced per seat or for the whole party
- Expired requests move to a history archive
- Direct merchant voucher: you pay the shop, the app holds no money
Use cases
- Someone buying a laptop, TV or appliance gets local shops to compete instead of checking each shop's price
- A buyer compares the best local shop bid with the best online price before deciding
- A sneaker or watch buyer posts the exact model and size and lets specialist shops quote
- A family asks travel agents to quote on flights to India, priced per seat or for the whole party
- A local shop finds buyers ready to purchase in its category and wins them by lowering its price
- A buyer gets an alert when an online price falls to their budget

JanHelp
Beta
v2.51.0
· Money & legal help
Help with money and legal problems in India: loans, cards and insurance compared from providers' own pages, and notices and complaints drafted and tracked.
Open to everyone on the web, with no sign-up. The Android app is not on Google Play yet: download the .apk and install it. Applying is in test mode.
What it does, features and use cases
JanHelp helps people in India with money and legal problems. Its agent part finds the right loan, credit card or insurance for a person and helps when something goes wrong with one: a refused claim, a wrong charge, a mis-sold policy. Its do-it-yourself part has legal, tax and government tools and calculators. It drafts the notice or complaint, tracks the deadlines it starts, and gives the steps to file it on the government's own portal.
Nothing is made up. Rates, fees, eligibility rules and premiums are read from each lender's, card issuer's and insurer's own published pages and checked again every night, and every answer says where it came from. No AI chatbot writes the answers. AI assistants such as Claude can use the same tools through JanHelp's MCP server.
It works in English, Hindi, Marathi, Tamil, Bengali and Telugu, and needs no account. What a person gives it is encrypted wherever it is kept: on the server, in the browser, and end to end in an optional passkey account. Each of its 110 features says who it is for and has a step-by-step guide, and 90 of them can be tried with a worked example.
Applying through JanHelp is in test mode for now: it records the application and prepares the papers, but nothing is sent to a provider yet. It gives tools and facts, not legal or financial advice.
Features
- Find my best options: a few questions, then one plan across loans, cards and insurance, showing what it assumed so you can confirm or change it
- Loans from 39 lenders' own published rates (112 products): home, personal, car, education, gold and property, with the rate for your credit score where the lender publishes one
- Can I get the loan: each lender's published rules on age, income, credit score and EMI share checked against you, with the rule's page linked
- A loan's true cost (APR as RBI's Key Facts Statement defines it), moving a loan and prepaying
- 60 credit cards from 10 issuers: the best card for what you spend, typed in or read from your statement
- Health, parents', term, motor, travel, home and accident cover, with premiums read from insurers' own charts where they publish them
- Claim help: a health plan checked against a family's illnesses, and a refused claim taken to the insurer and the Ombudsman with ready letters
- Banks' and insurers' complaint and Ombudsman records, and "Is it genuine?" checks against RBI and IRDAI lists
- Credit report reader for CIBIL, Experian, Equifax and CRIF reports, with the dispute for anything wrong
- Notices and complaints drafted: cheque bounce, tenancy, consumer, unpaid salary, RTI, cybercrime, affidavit, will and more
- Deadlines tracked from each document, with reminders before each one
- Tax: new or old regime, presumptive tax, advance tax interest and capital gains
- Government service guides, and district officials for 727 of India's 749 districts
- Scan with camera: documents read page by page, and what is read fills in the answers
- One search box that understands English, Hindi and Hinglish
- Works in six languages: English, Hindi, Marathi, Tamil, Bengali and Telugu
- Encrypted wherever it is kept, an optional passkey account with end-to-end encrypted copies, and "Delete everything"
- "Try an example" on 90 features, and a step-by-step guide to all 110
- An MCP server, so Claude, ChatGPT and other AI assistants can use its tools
- An Android app, and the website installs as an app
Use cases
- Someone wants a home loan and needs to know which lenders will lend to them, at what rate and EMI
- A family compares health cover for elderly parents with existing illnesses, and what each plan will and will not pay for
- A person whose cheque bounced sends a Section 138 demand notice and is reminded before the 15 days run out
- Someone whose health claim was refused writes to the insurer's grievance officer, then goes to the Insurance Ombudsman
- A borrower finds a wrong entry in their credit report and files the dispute, with RBI's 30-day rule and compensation
- A salaried person picks the tax regime that leaves them more money
- Someone checks a lender, loan app or insurer against RBI and IRDAI lists before paying anything
- A person picks the credit card that pays back the most on what they actually spend
- A citizen files an RTI application and knows when the 30-day answer is due
- A Claude user adds JanHelp as a connector and asks it to compare lenders' published rates

KidPoints
In testing
v1.0
· Education
A learning app for children from Reception to Year 13, with UK, US and India curricula: practice, lessons, courses and mock exams, plus games where the answers are part of the play.
Pre-launch: the web app runs on a test server and you need an account to sign in, so ask the owner. Android is in a Google Play internal test for invited testers; anyone else can install the .apk.
What it does, features and use cases
KidPoints is where a child learns and practises, from Reception to Year 13, following the curriculum and exams of the UK, the US or India. A child practises skills, reads a lesson for each one, works through courses and sits mock exams. They earn points for studying, within the daily and monthly limits of their parent's plan.
Questions come from about 5,600 skills. Each skill has its own question templates, banded easy, medium, hard and expert. Questions are generated in advance, checked by automated gates and stored before any child sees them. There are over 5,100 lessons and about 400 courses: school years by subject, the 11+, GCSE, A level, SQA, SAT, AP, CBSE, JEE, CUET and more. Each course is mapped to its official syllabus, with mock papers sized to the real ones and mark schemes that show every method and accuracy mark.
Learning also happens through play. In about two dozen open-source 3D games the questions are part of the game: the answer is a ring on a race track, a numbered pool ball or a creature to blast. There are walkable 3D Knowledge Towns built from the child's school year, with a teacher in every hall, and Hero City, where a child trains twenty superpowers. Branching stories and chess against a clock carry questions too. Working labs cover physics, music, Logo and Python coding, geometry, circuits, the periodic table and the solar system. In Debate Club a child argues a motion against a tutor.
Parents see progress and monthly mastery reports. Teachers teach from any course or their own edited copy, set homework, worksheets and tests, mark mock papers and plan revision for a class. A teacher can also add adults as students.
By default no child's words are sent to an AI model, and Debate Club's tutor is written in advance and stores nothing a child writes. The Android app is the same app as the website. No real children use it yet: it is in testing before launch.
Features
- Practice across about 5,600 skills from Reception to Year 13, banded easy, medium, hard and expert
- UK, US and India curricula: each region gets its own skills, spelling, money and grade names
- A lesson for nearly every skill: a hook, the big idea built up step by step, then worked examples
- About 400 courses: school years by subject, 11+, GCSE, A level, SQA, SAT, AP, CBSE, JEE, CUET and more, each mapped to its syllabus
- Mock examinations sized to the real paper, with mark schemes that show each method and accuracy mark
- Revision plans that start with the weakest units, with a technique week, mock papers and a rest week
- Points for studying, within the daily and monthly limits of the parent's plan, plus daily streaks
- Questions inside about two dozen open-source 3D games: rings on a race track, numbered pool balls, coins and creatures
- Knowledge Towns: walkable 3D subject towns built from the child's school year, with a teacher in every hall
- Hero City: train twenty superpowers over ten levels each, and solve a weekly mystery with every other player
- Working labs: physics bench, music sequencer, Logo and Python turtle, geometry board, circuits, periodic table, orrery and world atlas
- Branching stories and chess against a clock, with questions as part of the play
- Debate Club: pick a motion, read its facts, argue three rounds against a tutor, then get a score and a quiz
- Parent portal: progress, monthly mastery reports and weekly digest emails
- Teacher portal: teach from any course or your own copy; set homework, worksheets and tests; mark mock papers; plan revision for a class
- Adults can learn too: a teacher adds them as students
- Questions generated in advance and checked before serving; by default no child's words reach an AI model
Use cases
- A child practises their year's maths and English in short sessions and earns points within limits their parent sets
- An 11+ candidate follows a revision plan that starts with their weakest topics, then sits mock papers
- A GCSE or A-level student works through the course for their exam with worked examples and mark schemes
- A student in India prepares for CBSE boards or JEE, and a US student for the SAT or AP exams
- A parent sees what their child has mastered this month and where they are stuck
- A teacher teaches a class from a course, edits their own copy, sets homework and marks a mock paper
- A child who would rather play races a track or walks a Knowledge Town where every answer is part of the game
- A child practises arguing a case in Debate Club, then answers a quiz on the facts

Kinfolk
In testing
v0.3.0
· Family finance
One emergency fund for a family across the US, UK and India: anyone in trouble gets local money from their phone, and bigger amounts go to a family vote.
Open web demo, no sign-up: switch between family members to try it, or press Demo for the guided tour. All money is simulated. The free server can take a minute to wake up.
What it does, features and use cases
Kinfolk is one emergency fund for a whole family spread across the US, the UK and India: children, adults and elders. Family members add money in their own country, and anyone in trouble, anywhere, can get local money from their phone with nobody else awake. Bigger amounts go to a family vote.
In the US and UK the money is held as USDC in a family Safe that only the family's passkeys control. Licensed providers such as Coinbase, Robinhood, MoonPay, Transak, Ramp and Stripe take top-ups and pay members to their own account, card or bank, so Kinfolk never holds the money. In India the money stays in rupees, in a bank account two elders keep, used through UPI Circle. For now the India side is manual: payments happen in the UPI app and are recorded with their 12-digit reference.
The server enforces the rules, and every action is signed with a key on the person's own device. Up to $60 a day needs no one's say; up to $2,500 is paid instantly in an emergency and the whole family is alerted; above that, a request needs one or two approvals and is paid automatically once approved. Every top-up is kept under the giver's yearly gift-tax line in the US, the UK and India.
This is a working prototype: money movements, providers and notifications are simulated. A guided tour in the app shows every feature and can do each step for you.

Nexus Travel
In testing
v1.0.1
· Business travel
Business travel that plans itself around your meetings: your travel agents quote, online prices are compared and your manager approves, in one place.
The web demo is open to everyone: pick a demo company and person, no password. Android is in a closed test on Google Play: ask to join the testers list, then use the test link.
What it does, features and use cases
Nexus Travel is a business travel app for companies, built India-first. A traveller says where they need to be, typed or spoken, in English or Hindi. Nexus drafts the flights, hotel and transfers around the meeting, checks them against the company's travel rules, and sends the trip for approval only when the rules say so.
It works with however a company books today. Companies on Concur keep it, and Nexus adds pre-trip checks, money back and GST credit. Companies that book through local travel agents send each request to their agents by email or WhatsApp: Nexus reads the quotes, compares them with each other and with the online price, and shows when booking yourself would be cheaper. Companies that book on set websites such as MakeMyTrip get those sites opened already filled in, and the confirmation email becomes the booking.
Every trip shows its stage, who has it now and what happens next. Travellers can change or cancel a booked trip and see the cost before anything changes. Finance sees spend, money recovered and GST credit, and admins switch features on or off for their company.
Data is encrypted on the way and where it is stored, each company's data is kept apart, and roles decide who sees what. The Android app opens the same service and has a second door to Travel Haggle, for personal trips where agents compete to quote. The demo uses fictional companies: don't enter real personal details.
Features
- Plan a trip from one sentence, typed or spoken, in English or Hindi
- Every option checked against your travel rules: within the rules, outside your meeting times, or over the hotel limit
- Requests to the company's own travel agents by email and WhatsApp; their replies are read automatically
- Agent quotes compared with each other and with the online price, after GST credit, with baggage like for like
- Counter-offers that never name the other agent, and call or WhatsApp talking points in Hindi
- Book it yourself: told when online is cheaper than the agents, with rules and pilot groups to move trips over
- MakeMyTrip, Booking.com and the company portal opened already filled in; the confirmation email becomes the booking
- Approvals only above the limit, and for changes that add more than the company allows
- Trip stages with the next step and who has it; change or cancel with the cost shown first
- Concur add-on: passport and visa checks before the trip, duplicate and outside-the-tool spend, an approval assistant
- Money back: unused airline credits, refunds, compensation for cancelled flights and cheaper hotel rates
- India tax pack: GST credit audit, GSTR-2B, daily allowance, mileage and Tally export
- Traveller companion: when to leave, airport help, weather, metro, auto and cab options, receipts and expenses
- Admin console: features, travel rules, people and roles, single sign-on and two-step sign-in
- Encrypted in transit and at rest, each company kept apart, privacy controls for India's data protection law
- Android app with a second door to Travel Haggle for personal trips
Use cases
- A company already on Concur and a travel agency adds pre-trip checks, money back and GST credit without changing how it books
- A company that books through local agents by email and WhatsApp makes them compete and sees what they cost against online prices
- A company that tells staff to book on MakeMyTrip or its own portal gets approvals above a limit and every booking captured from the confirmation email
- A company with both: an agent books flights by email, employees book hotels online, and a trip with both is split between them
- A small company signs up on the Free plan and starts from empty
- A traveller with a client meeting gets flights, hotel and transfers drafted around it, then changes the trip when the meeting moves
- A manager approves only the trips and changes that go over the limit
- Finance recovers unused airline credits and claims GST credit on travel

OmniQA
Live
v2.0.0
· Developer tools
Tests apps for you: choose the testing, send the app's team one questionnaire, upload their answers, and download the reports.
A private web dashboard on our own server. The browser asks for the dashboard sign-in: ask the owner for it. App teams need no access; they fill in a questionnaire file sent to them.
What it does, features and use cases
OmniQA is an autonomous testing platform. Point it at a web app, including single-page apps and Pega, or at an Android or iPhone app. It explores the app, tests it and writes tester-grade reports: what passed, what failed with screenshots and traces as evidence, and a ready-to-run Playwright test suite.
Every kind of testing is opt-in. For each app you choose from 32 kinds of testing, such as journeys, accessibility, security, performance and APIs, or a preset such as smoke, accessibility or full. Nothing runs that was not chosen.
The Test plan page gets what the testing needs from each app's team. Choose the testing and it creates one questionnaire file with only the questions those tests need, each with its answer format and an example. The team fills it in, in any browser and even offline, and saves it. You upload it, check what is missing, and start testing. When the run finishes, everything downloads as one zip.
Passwords never go in the questionnaire. They are typed in at upload and kept in memory for that run only. Integrations are tested with sandbox keys only, and live keys are refused. Security checks are defensive and are not a penetration test, which stays human-led. Load tests stop on their own if the app starts failing.
Features
- 32 kinds of testing, every one opt-in: choose per app, or a preset such as smoke, accessibility or full
- Exploratory testing: fills and submits forms with valid and boundary data and reports anomalies
- Runs your business journeys and business rules step by step, signed in as each role
- Accessibility: axe-core WCAG 2.2 AA scan, keyboard walk, focus visibility and a screen-reader transcript
- GOV.UK accessibility when chosen: Design System, content style, accessibility statement, and 320px, no-JavaScript and forced-colours checks
- Defensive security: headers, cookies, TLS, exposed files, what each role can reach, and privacy and consent
- Performance: Core Web Vitals, screen-change timings, load with a circuit breaker, and what users see when an API fails or the network is slow
- API contract and input validation, learned from traffic or OpenAPI; sandbox checks of payment, email and other integrations
- Single-page apps and Pega, including WebSocket, server-sent event and polling checks
- Responsive layout, Chromium, Firefox and WebKit, visual regression, localization and SEO
- Native Android and iPhone apps over adb or Appium
- Test plan page: choose the testing, send one tailored questionnaire, upload the answers, start testing
- The questionnaire works offline in any browser, keeps a draft, and refuses answers that look like passwords
- Reports with evidence, a coverage and readiness summary, and a generated Playwright test suite, all in one download
Use cases
- A team about to release wants its web app's journeys, accessibility, security and performance checked in one report
- A product owner sends each app team one questionnaire, gets it back filled in, and starts testing without a round of meetings
- A public-sector service checks itself against GOV.UK accessibility and the Design System before an assessment
- A developer takes the generated Playwright suite for their app's journeys and keeps running it in CI
- A Pega or single-page app team tests screens that change without the address changing
- An app team checks that each role, and visitors who are not signed in, can reach only what they should
- Before launch, a team checks Core Web Vitals and how the app holds up under load and when an API fails

PetWithBrain
In testing
v1.1
· Pets & wildlife
A 3D pet with a brain modelled on how real animals learn: it learns tricks, words and your routine from you, on your phone.
The web app opens in any browser. The Android app is in an internal test on Google Play: testers on our list open the test link, accept the invite and install it from the Play Store.
What it does, features and use cases
PetWithBrain is a 3D pet, a dog or one of three original creatures, run by a brain modelled on how real animals learn. Nothing is scripted: every trick, word and habit comes from what happens to it. A reward it didn't expect teaches it the most, sleep makes the day's learning last, its feelings speed up or slow down its learning, and each pet is born with its own temperament.
You teach it with treats, praise, touch and your voice. It learns your routine, the people it meets, the names of its toys and the words on its talking buttons. Mind → How it learns shows what is helping or holding back its learning right now and what makes its brain different; the learning journal shows everything it is learning, day by day.
Its brain runs on the phone and works with no network. Backups are end-to-end encrypted with a recovery code only you have, the service is HTTPS only, and Android's own backup never takes your sign-in or recovery code to the cloud.
For testers, You → Try every feature explains each feature and shows where it is, with a demo pet that already has three weeks of history.
Features
- Learns tricks on your own words, rewarded with treats, praise or a stroke
- Touch: scratch, cuddle and hug it, draw hand signs, tap the floor to call it over
- Talk & see: it learns your voice, your face and hand signals through the microphone and camera (opt-in, adults only)
- Learns your daily routine, the people and animals it meets, toy names and talking buttons
- Copies moves you show it ("do as I do") and puts tricks together into new moves of its own
- Mind → How it learns: what is helping or holding back its learning right now, and what makes its brain different
- Learning journal: every trick, word and person it is learning, day by day, with what is fading
- Why did it do that? Its reasons, from its own brain
- Demo pet with three weeks of history, and a Try every feature guide for testers
- End-to-end encrypted backups; works offline
- Eight languages: English, Spanish, German, French, Portuguese, Hindi, Japanese and Chinese
- Children's mode, and a care summary for carers and families
Use cases
- Someone getting a real puppy practises training on a twin of it first
- A family wants a pet that truly learns from them, with a children's mode for the youngest
- A care programme gives older people a companion that knows them, with a weekly summary for carers
- A classroom runs classic animal-learning experiments in the Lab
- A shelter lets would-be adopters try caring for a pet before they adopt
- Anyone curious about how animals learn watches it happen, with the reasons shown

QuantaProof
Beta
v2026.10.05
· Trust & safety
Checks whether an image, voice clip, document or video has been edited or made by AI, and shows the evidence for each finding.
Free on the web. The quick public check needs no account; the full examination needs a sign-in. Research prototype, non-commercial use only.
What it does, features and use cases
QuantaProof examines an uploaded image, audio clip, document or video with a panel of independent forensic tests: metadata and file structure, compression history, content credentials (C2PA), a tamper localiser that marks edited regions, and learned detectors for AI-made pictures and cloned voices. It reports what each test found rather than a bare verdict.
Each test's false-alarm limit is set from real genuine files of the same kind (camera photos, WhatsApp forwards, voice notes, phone recordings, scans and identity documents), and the whole panel shares one limit, so about 5% of genuine files are flagged by design.
Measured on files it was never trained or calibrated on: AI voice clones in Indian languages, across four channels (as published, voice note, phone call, wideband call), 317 of 400 caught (79%) while 17 of 480 genuine FLEURS speech files were flagged (3.5%); AI images from 10 generators it never trained on, 274 of 400 caught in the standard scan (68.5%) and 340 of 400 in the advanced scan (85%). Video detection is still weak, and false alarms on genuine Indian-language speech are being re-measured.
A research prototype: several of its detectors carry non-commercial licences.
Features
- One upload checks images, audio, documents or video
- Quick public check in plain language, no account needed
- Evidence from each test instead of a single verdict
- Tamper localiser that marks the edited region of a photo or document
- Advanced scan with extra AI-image and AI-document detectors
- AI voice-clone detection calibrated on Indian-language speech
- Reads C2PA content credentials, including OpenAI's
- False-alarm limits set per kind of file from real genuine files
Use cases
- Checking a WhatsApp forward before sharing it
- Fact-checkers and newsrooms screening user-submitted photos and clips
- Spotting AI-cloned voices in voice notes and calls
- Screening scanned documents and receipts for edits or AI-redrawn regions
- Researchers measuring detector false alarms on real-world media

TerraGuard
In testing
v2.8.2
· Safety & family
Family safety SOS that gets through without mobile data: alerts, fall detection, walk-home and ride checks, built for India.
The web app is open to everyone. The full Android app (power-button SOS, fall detection, SOS with no signal) is in Google Play internal testing: ask the owner to add your Google account, then use the test link.
What it does, features and use cases
TerraGuard is a family safety app built for India that gets an SOS through even when there is no mobile data. Hold one button, or press the power button three times with the phone in your pocket, and your family, your emergency contacts and, if you switch it on, 112 get your exact position, battery and what's wrong. With no data it goes by text message, by satellite on phones that support it, or phone-to-phone over Bluetooth. A family member with a basic phone can raise the alarm with a missed call or a "HELP" text.
It also acts when you can't ask for help. Fall and car-crash detection run on an on-device AI model, "walk me home" and ride check follow you until you arrive, and a phone snatched from your hand sends its location to your family. Family live location, place alerts and check-ins are end-to-end encrypted, and sharing is always visible and can be paused.
Everything the app saves is encrypted on the phone with a key held in its secure hardware, the server can't read family locations, check-ins or messages, and there are no ads. A practice mode lets anyone try SOS, countdowns and alerts without reaching anyone.
Features
- Hold-to-SOS: family, contacts and (in India, if switched on) 112 get your position, battery and what's wrong
- Power button 3 times with the screen off, with a 10-second countdown and a big Cancel so a press by mistake alerts no one
- SOS without mobile data: by text message, by satellite on phones that support it, or phone-to-phone over Bluetooth
- Family members with a basic phone alert everyone with a missed call or a "HELP" text
- Fall and car-crash detection with an on-device AI model: a countdown, then help is called
- Walk me home and ride check: share an Uber, Ola or Rapido trip, and any SOS during a ride names the vehicle
- Night routes that prefer lit, busy streets and avoid spots where several people felt unsafe
- Phone-snatch alert: if the phone is grabbed and not unlocked within a minute, the family gets its location
- End-to-end encrypted family live location, place alerts, check-ins and "Is everyone safe?" roll calls
- Ask family for a recharge when out of data or talktime, even by text message with no internet
- "Is it really them?" check against voice-cloning scams, a family safe word and the 1930 cyber-fraud helpline
- Danger alerts: official weather and disaster warnings, nearby wildfires, a battery that won't last the trip
- Offline first aid and safety advice in English and Indian languages, offline maps and emergency phrases in 27 languages
- Practice mode: try SOS, countdowns and alerts without reaching anyone
- Saved data encrypted on the phone with a hardware-backed key; no ads, data never sold
Use cases
- Someone walking home late shares the walk, and the family is alerted if they stop or don't arrive
- A rider shares their Uber, Ola or Rapido trip; an SOS during the ride gives the family and police the vehicle number
- An elderly parent living alone falls: TerraGuard counts down, then alerts the family with the location
- A parent with only a basic phone texts HELP or gives a missed call, and the whole family is alerted
- Trekkers, or people in a flood with the network down, still send an SOS by text, satellite or phone-to-phone over Bluetooth
- After an earthquake, flood or cyclone nearby, the family runs an "Is everyone safe?" roll call
- A caller sounding like your son asks for money urgently: one tap asks him directly on his own phone
- A teenager runs out of data and asks a parent to recharge; the parent approves and pays from their own phone
- A phone is snatched: the family gets its location, and the app shows how to block the SIM and report it on Sanchar Saathi
- A company's night-shift staff share their ride home with the safety desk, with their consent

TradeFlow AI
In testing
v2.0.0
· Trade finance
Invoice discounting for Indian supply chains: checks each GST e-invoice against the order and delivery, then lets banks bid to pay small suppliers early.
Open web demo with no sign-up. The companies are fictional and government and bank systems are simulated, so no real money moves. The free server can take a minute to wake up.
What it does, features and use cases
TradeFlow AI is invoice discounting for Indian supply chains. A supplier's GST e-invoice is matched line by line against the buyer's purchase order and goods receipt, pulled from SAP, Tally or GeM. Before any money moves it is checked against India's own systems: the IRN on the e-invoice portal, the e-way bill, FASTag toll crossings on the route, the buyer's decision in GST's Invoice Management System, CERSAI, and a shared registry that stops the same invoice being financed twice.
The buyer approves verified invoices in one signed step, and banks and NBFCs bid in a reverse auction to pay the supplier early. The amount funded is net of TDS and of the GST TDS government buyers deduct, with GST held back until the buyer can claim it. Small buyers that no bank has a limit on are priced by credit grade, and CGTMSE or NCGTC guarantee cover lowers the bid. Suppliers can draw money on WhatsApp in Hindi, Gujarati or Tamil, by text or voice note, after a Key Fact Statement and an OTP.
Buyers see the 43B(h) tax at risk and the MSMED interest building up on late payments to small suppliers, and get MSME Form I. Public sector companies get their GeM orders and their duty to settle MSME invoices through TReDS handled. Financiers get supplier KYC and land records through RBI's Unified Lending Interface, credit memos built from Account Aggregator and GST data, e-NACH collections and guarantee claims.
This is a working sandbox: the companies are fictional and the government and bank systems are simulated, so no real money moves. The demo page runs 32 journeys for 10 personas on the server and shows what each step returned; the API is documented at /docs. Running it for real needs a TReDS licence or lender partners, and access to each government system.
Features
- GST e-invoices, SAP, Tally and GeM orders matched line by line against the purchase order and goods receipt
- Split approval: the undisputed part of an invoice is funded now and the disputed part held, with a dispute playbook
- Fraud checks before money moves: IRN, e-way bill, FASTag toll trail, GSTIN status, CERSAI and circular trading between related companies
- A shared registry that stops the same invoice being financed at two lenders, without revealing either lender's book
- GST Invoice Management System: the buyer's reject blocks funding, and its accept releases the GST part early
- Funding net of TDS under the Income-tax Act, 2025 and 2% GST TDS for government buyers, with GST held until the buyer's GSTR-2B
- One signed approval for a batch of invoices, standing auto-approval rules, and early payment from the buyer's own cash
- Reverse auction among banks and NBFCs, within each lender's limit on the buyer
- CGTMSE (75%) and NCGTC (60%) guarantee cover priced into bids for small buyers, and the claim after a default
- Key Fact Statement with the all-in APR before any drawdown
- Drawdowns on WhatsApp in Hindi, Hinglish, Gujarati and Tamil, by text or voice note, confirmed with an OTP
- Deep-tier finance: a Tier-1 supplier passes part of its claim on the buyer to its own supplier, backed by that supplier's invoice
- Supplier KYC, credit report and land records through RBI's Unified Lending Interface; a failed KYC blocks financing
- Credit memos in seconds from Account Aggregator bank data and GST returns, with every source listed
- e-NACH collection on the due date, a virtual account per invoice, and alerts for credit notes, IMS rejections and payments to the wrong account
- 43B(h) tax at risk, MSMED interest, MSME Form I and MSME Samadhaan claims
- Export invoices from PEPPOL countries priced in dollars from GIFT City
- Tamper-evident audit log, restart without losing state, and role-scoped API keys
Use cases
- A micro supplier in Gujarat draws ₹3 lakh against an approved invoice by typing in Gujarati on WhatsApp
- A manufacturer's AP team clears verified supplier invoices with one signature and avoids the 43B(h) tax hit
- A supplier whose delivery was partly rejected gets the accepted part funded now instead of waiting for the dispute
- A micro supplier's invoice to another small firm is financed at a lower rate because of CGTMSE cover
- A GeM seller to a public sector company is paid soon after the consignee accepts, funded net of the GST TDS the company will deduct
- A Tier-2 steel supplier is financed at the anchor buyer's rate instead of borrowing informally
- A bank onboards a supplier through ULI without PAN copies or a cancelled cheque, and spots a settlement account in someone else's name
- A lender stops an invoice already financed at another bank, or one whose goods never crossed a toll plaza
- A public sector company's finance team sees which MSME bills it settled outside TReDS

UK Self Assessment Tax Calculator
In testing
· Tax & finance
Estimates a UK Self Assessment tax bill and what to pay by 31 January and 31 July, as GOV.UK-style pages, inside another app, or through an API.
A test site, open to everyone, with dummy HMRC, GOV.UK One Login, Notify, DVLA and Budget Payment Plan services. Use the test customers, not real personal information. The first visit can take about 30 seconds while the site wakes up.
What it does, features and use cases
The calculator works out a UK Self Assessment tax bill for the tax years 2023 to 2024 up to 2026 to 2027. It covers Income Tax in England, Wales, Northern Ireland and Scotland, National Insurance, Capital Gains Tax, student loan repayments, the High Income Child Benefit Charge and pension charges. It then shows what to pay and when, including payments on account. Every rate and allowance comes from GOV.UK or legislation.gov.uk, and the pages follow the GOV.UK Design System.
It can be used in 3 ways. Customers can answer one question per page and see the bill with the working. Another app can put the question pages inside itself. It sends the customer with what it already knows, and gets them back with the tax and what to pay when. Or software can call the API, for the full calculation or one part at a time from the least it has, such as pay alone.
An administrator chooses which of 22 parts of the calculator are used, for example basic Income Tax only. They also choose which ways are open, where answers are read from HMRC records instead of asked, and how much working the result shows. Each organisation using the service has its own settings, managed by the service administrator or its own administrators. Customer accounts keep a forecast up to date during the year, and an optional feature works out Budget Payment Plan amounts.
It is tested in 5 ways: 121 hand-worked customers, 42 end-to-end journeys, 376 threshold checks, 20,000 random customers checked against a separately written calculation, and 97.8% code coverage. In all, 1,039 automated tests pass. The test site uses dummy versions of HMRC, GOV.UK One Login, Notify, DVLA and a partner app, with 14 test customers and 3 example organisations.
Features
- Income Tax for every kind of income on a return: pay, self-employment, partnerships, property, pensions, savings, dividends, foreign income, trusts and life policy gains
- Scottish Income Tax, National Insurance, Capital Gains Tax, student loans, the High Income Child Benefit Charge and pension annual allowance charges
- What to pay by 31 January and 31 July, with payments on account, collecting a balance through a tax code, and late filing and payment penalties
- 22 parts of the calculator that can be switched on and off, or ready-made sets such as Basic Income Tax
- 3 ways to use it: full question pages, question pages inside another app, and API calculations
- Question pages inside another app: the app sends what it knows and gets the customer back with the tax and what to pay when
- API calculations in full or one part at a time from minimal figures, such as pay alone
- Settings for each organisation, with its own web address, administrators and API keys
- Answers read from HMRC records with the customer's permission, chosen separately for each way of use
- Allowances set against income in the way that gives the lowest tax, as the law requires
- Customer accounts with GOV.UK One Login and a forecast kept up to date during the year
- Budget Payment Plan amounts, straight from HMRC account data or through a hand-off from HMRC's service
- Service overview pages with every feature, use case and test result
Use cases
- A sole trader estimates their bill before filing and sees how much to pay in January and July
- An accountancy firm gives its clients the full question pages at its own web address, with answers read from HMRC
- A payroll app puts basic Income Tax questions inside its app and gets each employee's estimate back
- A software company calculates tax through the API from the least it has, such as pay alone
- An organisation's administrator switches parts of the calculator on and off and manages its API keys
- HMRC's Budget Payment Plan service sends a customer to work out a fixed weekly or monthly amount, then gets them back with it
- A customer tracks their tax during the year and gets an email when their forecast changes
- A team shows people how the service works and how it was tested, using the service overview pages
