Building Goka AI — turning photos into videos
Notes on shipping an AI video app with Expo, Supabase and a credit system that refunds failed creations automatically.
Goka AI started with a simple question: how few taps can it take to turn a single photo into a video people actually want to share?
Templates first
Prompts are powerful, but most people don’t want to write them. So Goka leads with trending templates — pick one, add a photo, done. Prompting is still there for anyone who wants full control.
A fair credit system
Every creation shows its price up front, and if a generation fails the credits are returned automatically. It sounds small, but it’s the difference between a tool you trust and one you don’t.
The stack
- Expo + React Native with expo-router
- Supabase for auth, storage and edge functions
- RevenueCat for subscriptions and credit packs
