Computer Vision
Object detection that runs live, right there on the page. Point it at things to detect them, estimate calories, check how busy a cafe is, or follow a padel match. Nothing you see ever leaves your device.
Open Computer VisionApps, experiments,
and ideas.
Made to be used.
Here is what you will find: machine learning apps you can open and use straight away, native iOS apps for the iPhone, and a pile of small apps, quizzes and games we built for the fun of it, and to see how far the ideas go.
Experiments
A web page can do more than you think.
Two live models you can open right now. Nothing to install and no account to make. Just your camera, or your cursor.
Draw AI
Sketch anything and watch a model trained on 95 categories try to name it while you are still drawing. A test of your drawing, and of its eyesight.
Open Draw AI
iOS apps
Focused apps for iPhone.
Native SwiftUI, private by default, happy offline. Each one started as an experiment on this site.

Free, and free of ads. We build the things we find useful ourselves. If there is an app you wish existed, tell us and we will be glad to make it and give it away.

Play
Quick to open. Easy to put down.
Small things for a short break: a quiz, a game, a piano, a quiet room. Nothing to install.
Quizzes
Flags, capitals, populations and the Arab world. Play solo against the clock, or open a room and race your friends live.
Open quizzesGames
Two flavours of Snake, XO against an AI you will not beat, a tank defence, and a team picker for when nobody wants to choose.
Open gamesVirtuoso Piano
A real piano that just opens. Free play, a practice mode that waits for the right key, guided lessons, and about thirty tracks to learn.

Mix rain, fire and ocean into your own soundscape with Sukoon, then breathe with Tanaffus. One calm corner of the internet.

Partnerships
Joint projects, pilots and collaborations that last. We like working alongside people and teams on something where an app or a tool would genuinely help.
AI and machine learning
Models that actually ship. Ours run on a phone or on a web page, in front of a real person, rather than sitting in a notebook.
Computer science
Cybersecurity, programming in Python and C/C++, algorithms, and data analysis and visualisation. The engineering underneath, and the part that has to hold up once other people depend on it.

In development
Real products are on the way.
Leave your email and you'll get one message when something ships. No spam, just the good stuff.
You're on the list.
Thanks for signing up. We'll be in touch at when we launch.
