StudyFox AI is a study workspace that converts your own course material — PDFs, lecture slides, screenshots and rough notes — into flashcards, practice quizzes, structured notes and interactive mind maps. A Chrome/Edge extension solves questions directly inside Canvas, Blackboard or Moodle and shows step-by-step reasoning, while spaced repetition keeps the material you keep missing coming back.
