What it does: - Paste any recipe URL or text → AI extracts structured recipe data - Automatically detects timers in instructions ("bake for 25 minutes" → countdown button) - Scale servings up/down with automatic ingredient recalculation - Track your progress with checkable ingredients and steps
Tech stack: - Frontend: Expo (React Native) with TypeScript for iOS/web - Backend: Supabase (PostgreSQL with JSONB for flexible schema) - AI: OpenAI GPT-4o-mini for parsing - Deployed on Vercel
The interesting technical bit: I went with a "dumb scraper, smart parser" approach. Instead of trying to handle every recipe site's HTML structure, I just fetch the raw HTML and let GPT-4o-mini extract the recipe. It handles weird formats, handwritten recipes, even recipes pasted from emails surprisingly well.

iOS version coming soon (currently in TestFlight)
Would love feedback on the UX and what features you'd want in a recipe app!
