🧠 I built an AI Exam Prep PWA (React + Groq LLaMA 3.3) — 100% Free

Hey everyone! I’m a student developer from Mumbai, and I just launched ExamBrain.

I got tired of the manual grind of turning massive lecture notes into actual study material, so I built an AI-powered tool to completely automate it in seconds.

Just paste your notes, and it instantly generates a custom study toolkit:

◦ Smart Quizzes: 10 MCQs with Easy/Medium/Hard difficulty tracking.
◦ AI-Graded Short Answers: Get instant feedback on your written answers.
◦ Interactive Study: 3D flashcards featuring Text-to-Speech (TTS).
◦ Deep Analytics: Score reports with topic breakdowns and weak-area alerts.
◦ Smart Retries: Focus your energy by retrying only the questions you missed.
◦ Zero Friction: Installs on your phone as a PWA, works offline, and requires no signup or credit card to try.

Tech Stack:

◦ Frontend: React + Vite + Tailwind CSS.
◦ Backend: Serverless Architecture.
◦ AI Engine: Groq (LLaMA 3.3 70B).
◦ Database: Supabase.
◦ Hosting: Vercel.

I’d love for you to test it with your notes! There’s a Reviews tab built right into the app, or you can drop feedback, feature ideas, or bug reports in the comments.
