I got tired of making quiz questions by hand.
In 2026, I built an app covering 21 K-12 subjects with 380,000 questions. Users loved it — but the bottleneck was real: every new course meant manually structuring its knowledge tree from scratch.
This scaffolding should work like this: you throw in a textbook, a paper, or a lecture transcript — it automatically breaks down the knowledge points, maps their dependencies, and generates a complete, structured question bank aligned with the Ebbinghaus Forgetting Curve. Not a pile of random questions, but every question precisely placed where it belongs in the knowledge structure.
I call it ChooseWiki. For learners, it's a scientific study tool. For content creators, it's a "content → question bank" production engine. For the world, it's an open marketplace for knowledge quizzes.
