How I Built ChefMate — An AI Recipe App for Hostel & PG Students

Most recipe apps assume you already have a full kitchen.

But during college and hostel life, the reality is usually:
onion + potato + maggi + random masalas 😭

That simple problem became the idea behind ChefMate.

I wanted to build something where users could simply select the ingredients they already had available and instantly generate quick Indian-style recipes instead of endlessly searching YouTube or recipe blogs.


🚀 What is ChefMate?

ChefMate is a full-stack AI-powered recipe and meal planning platform built using the MERN stack.

Users can:

  • generate recipes using available ingredients
  • use a guided Cook Mode
  • save recipes
  • create meal plans
  • share recipes using public links
  • browse additional recipes using TheMealDB API

The focus was making the experience simple and practical for students, hostel residents, and bachelors living alone.


🛠️ Tech Stack

Frontend

  • React
  • Vite
  • Tailwind CSS
  • React Router
  • Axios
  • React Hot Toast
  • React GA4

Backend

  • Node.js
  • Express
  • MongoDB
  • Mongoose
  • JWT Authentication
  • Express Rate Limit
  • Zod Validation

AI & APIs

  • OpenRouter API
  • Gemini / Llama / Mistral models
  • TheMealDB API

✨ Features I Added

🤖 AI Recipe Generator

Users select ingredients and preferences like:

  • vegetarian/vegan
  • cooking time
  • dietary preferences

The app then generates structured recipes with:

  • ingredients
  • cooking steps
  • health benefits
  • estimated cooking time

🍳 Cook Mode

One feature I personally liked building was Cook Mode.

Instead of showing a giant recipe paragraph, the app guides users step-by-step while cooking.

I also added:

  • progress tracking
  • timers
  • step navigation

to make the cooking experience smoother.


📅 AI Meal Planner

Users can generate meal plans for multiple days based on:

  • calorie goals
  • diet preferences
  • number of days

🔗 Shareable Recipes

Users can generate public recipe links and share them directly through WhatsApp or browser sharing APIs.

Shared recipes can be opened without login.


⚡ Biggest Challenges

1. Making AI responses consistent

LLM outputs are unpredictable.

Sometimes responses came as:

  • JSON
  • markdown
  • incomplete text
  • broken formatting

So I had to build normalization and validation logic to structure responses properly.


2. UI/UX Problems

One thing I learned quickly:
good functionality alone is not enough.

Early feedback made me realize:

  • the UI felt too “AI-generated”
  • layouts were inconsistent
  • some flows were confusing

I spent a lot of time refining:

  • spacing
  • typography
  • visual hierarchy
  • loading states
  • mobile responsiveness

3. Public Feedback & Distribution

I recently started sharing the project publicly and learned that distribution is honestly harder than coding sometimes 😭

Posting on communities taught me:

  • how people perceive AI products
  • how important positioning is
  • how to communicate projects naturally instead of sounding overly promotional

That was a surprisingly valuable learning experience.


🔒 Security Improvements

One important issue I discovered after feedback:
the AI endpoints initially had no proper rate limiting.

Since LLM APIs cost credits, users could theoretically spam requests.

I fixed this using Express Rate Limit to protect expensive endpoints.


📈 What I Learned

Building ChefMate taught me much more than just coding:

  • shipping real products
  • handling user feedback
  • improving UX
  • API security
  • analytics integration
  • authentication flows
  • real-world deployment

It also made me realize:
building something usable is much harder than just making something functional.


🔮 Future Plans

Some things I’d like to improve:

  • recipe images/videos
  • grocery list generation
  • better onboarding
  • stronger personalization
  • social/community features

Would genuinely love feedback from other developers/builders on:

  • UI/UX
  • product direction
  • architecture
  • ideas for improvement 🙌
