ChefGPT

An AI-powered recipe generator built with the MERN stack and Groq (Llama 3.3).

Describe what you want to eat, what ingredients you have, or any cuisine — ChefGPT generates a complete recipe with ingredients, step-by-step instructions, prep/cook times, and more. Every recipe is saved to MongoDB so you can build your own cookbook over time.

Stack

• Frontend — React 18, Vite, React Router, Axios
• Backend — Node.js, Express (ESM)
• Database — MongoDB Atlas, Mongoose
• AI — Groq API (Llama 3.3 70B)
