How it works

You talk. It builds. You check.

You come in three times. The AI does the rest.

  1. 1You

    Describe it

    In your own words. It asks before it builds.

  2. 2AI

    It plans, builds and checks

    You pick from pictures. It builds and proves it.

  3. 3You

    Check the result

    Try the real thing. Nothing goes live without your go.

Included free

What you'd worry about. Handled.

  • No leaked keys

    Secrets stay out of your code.

  • Tested like a real user

    It taps through your app and fixes what breaks.

  • Accessibility first

    Clear order, readable text, one obvious action.

  • Remembers decisions

    New asks are checked against old decisions.

  • Ships reliably

    You say ship. It checks the live app still works.

  • Knows how your app works

    One change, made everywhere it's mentioned.

Free and Pro

Free to start. Pro to go further.

Pro is years of shipping real apps, written down for your AI.

Who's behind it

Viktor Stojanov. A real person, building real apps.

A head of engineering with 15+ years of building apps and the teams that make them. In Berlin, I run Stojanov Ventures, a small lab that builds its own apps: Rather, Runde and Activities Matter.

Solid Vibes is how I build them now, written down so you can build the same way.
