Maia

Maia maps your level in every area with an assessment that adapts to your answers, finds the most important gaps and guides you to close them with methods research backs: the Feynman technique, retrieval practice, spaced repetition. What you learn ends up in a personal wiki you can browse.

It is the third time I circle the same idea. Cosmoscope started from a question, Upstream from interests; Maia starts from what you know and what you do not, and it is the one that got furthest. The taxonomy covers 19 areas, every screen talks to the real backend and a panel keeps track of model spend.

I first built the whole frontend on fake data, then the backend replaced it one slice at a time, with tests checking the full loop.
