GeniusPal

GeniusPal turns the material a student already has (lecture notes, a textbook PDF, slides) into practice questions, so revision means testing yourself rather than re-reading. Upload a file and it generates a study set of exam-style questions written from that file. Study it as a multiple-choice quiz, as flashcards, or in active-recall mode, and re-sit a set as often as you like. Questions you keep missing come back in a daily review, and a coach names the patterns in your mistakes. The free plan gives every account two study sets with no card. Paid plans start at $7.99 a week.
