## Summary

The USMLE Vault tutor is an AI tutor built on Google's Gemini Pro that floats on every screen of the app, including Anki. It knows which First Aid page, system or screen the student is on, and answers every study question in 3 fixed parts: what it is in plain words, how it happens step by step, and how the USMLE tests it (vignette clue, buzzwords, commonest trap, one line to memorise). It also knows the app itself and answers 'where is X / how do I do Y' questions with exact screens and buttons, and points to the free guides. 30 questions a day.
