How Sofnet builds tools
No sign-up, right away
The first screen is the tool. You should be able to try it in this browser before creating an account or installing anything.
Your data stays on your device
Face photos and documents are never sent to a server. Computation finishes in your browser or on your phone; you share only the result, only when you choose.
One tool for one moment
Instead of one super-app with everything, we build a small tool for each concrete moment — a magic trick, a daily puzzle, a focus-play session with your baby.
