Studify: AI Study Companion
A full-stack MERN app where students upload their notes and slides, then chat with them, get instant summaries, generate quizzes, and track progress, all grounded in their own material.
The solution
Studify centralizes uploaded course material and grounds every AI feature (chat, summaries, and quizzes) in a custom retrieval-augmented generation (RAG) pipeline, so answers cite the exact source notes instead of guessing.
Key features
- AI chat that answers from your notes, with source citations under every reply
- One-click document summaries, exportable as PDF or CSV
- Auto-generated multiple-choice quizzes with instant scoring and explanations
- Study analytics and an AI study coach that reads your activity and streak
- Secure accounts with email OTP sign-up, JWT auth, and password reset
Technology
- React
- Node.js
- Express
- MongoDB
- Groq
- Transformers.js
Results
- Custom RAG pipeline with local neural embeddings, no external vector database or embeddings API
- Every AI answer, summary, and quiz is grounded in and cited from the user’s own uploaded material
- Shipped and deployed end-to-end across Vercel, Railway, and MongoDB Atlas
