Inspiration

Rising food costs and lack of nutrition knowledge is a global crisis. 30% of food purchased goes to waste, and households struggle to balance health goals with tight budgets. We asked: What if AI could start with your budget, not recipes?

What it does

Cook Healthy AI is an AI-powered meal planning platform that:

  • 🧠 Generates personalized weekly meal plans based on your budget first
  • 📸 Scans food photos for instant nutrition analysis
  • 💬 Provides a conversational AI wellness coach
  • 🛒 Creates smart shopping lists with cost estimates
  • 📊 Tracks health impact, savings, and cooking streaks

How we built it

  • Frontend: Next.js 16, React 19, TypeScript, Tailwind CSS, Framer Motion

  • Backend: Supabase (PostgreSQL, Auth, Storage)
  • Architecture: Budget-first algorithm that maximizes nutrition while minimizing cost

Challenges we ran into

  • Gemini Vision integration for accurate food photo analysis
  • Building a budget-first AI platform that generates realistic, affordable meal plans
  • Internationalization to make the app work globally with USD pricing
