Software shaped for humans.

A studio building AI-native apps with a privacy-first, offline-first philosophy. Sometimes one of us, sometimes a few of us. Always intentional.

What we believe

Built for the user, not the dashboard

We design for the person actually using the app at midnight, not the analytics meeting next Tuesday.

Private by default

Your data stays on your device unless you opt in. No 'we anonymize it' fine print.

Slow software is broken software

If the app makes you wait, the app is the bug. Native, fast, offline-first.
