Drop a PDF of your notes and an LLM turns it into a Duolingo-style game you play in the browser. I built the whole thing — parsing, AI pipeline, game, and cost controls.

Drop a PDF and an LLM builds a full quest — units, crowns, streaks, XP. This one's generated from a real course PDF, not a canned demo.

Every question has a second step that teaches the reasoning — active recall that actually sticks, not just memorising.
