Hey Product Hunt! 👋
I built StudyIndex because I was spending more time organising my study material than actually studying it. Making flashcards from a 400-page textbook should not take 3 hours.
The core insight: the hardest part of studying is not the studying itself — it's knowing WHAT to study, WHEN to review it, and whether you actually understand it. StudyIndex solves all three.
A few things I'm especially proud of:
- The PDF extraction drills down to specific, atomic sub-topics (3–6 per chapter) — not just chapter names
- Practice exams in 3 real formats: MCQ for recall, Short Answer for understanding, Long Essay for synthesis
- Ambient sounds (wind, rain, ocean) generated in-browser via Web Audio API — no YouTube rabbit holes
Built with Gemini 2.5 Flash, Firebase, React + Vite, and a Workbox service worker for offline support. Free to use, no account needed to try it.
Would love feedback from students or anyone who has survived an exam week. What would make this 10x more useful for you? 🙏
