Four steps, one filter
Goes in the box
Every app starts as a small, annoying problem from daily life: a forgotten ferment, an idea lost in the shower.
Built fast with AI
The first version is built together with an AI coding assistant. That's how one person can try many ideas.
Tested for real
The prototype gets used at home for weeks. If it isn't useful every day, it stays in the box.
Comes out
The survivors get polished, translated, tested on real devices, and published on the stores.
Built with AI. Decided by a human.
The code in these apps is written mostly with AI tools. What's not automated: choosing what to build, deciding how it should feel, using it every day, and saying no to features that don't belong.
The typing
Writing code, tests, translation drafts, and a lot of the repetitive work.
The deciding
Ideas, design, priorities, daily testing, and what gets shipped.
Your data stays yours
No account walls, data on your device.
Real support
Every message is read by the person behind the apps.
