Source-grounded everything
Drop in PDFs, DOCX, YouTube videos, photos, or pasted notes. Lumen reads them and grounds every answer, quiz, and explanation in your actual material — not made up.
Adaptive Smart Quiz
20 questions in 6 batches, difficulty climbing as your XP rises. Partial-credit short answers. Time limits if you want them. Magic-lumen loaders between batches.
Leaderboards · Streams · Forum
Pick a stream — Knight, Doctor, Merchant, Magician, Scientist, Governor — and level up. School-scoped leaderboard + WhatsApp-style forum where bubble colour = your stream level.

Why does this exist?
Most study apps are designed for students. Lumen is designed byone. I tried almost every paid study tool — they're all great at something, none of them perfect. So I built the one I actually wanted: the best parts combined, gamified properly, and tuned for how students really study.
