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.

Screenshot a question inside Canvas, Blackboard, Moodle or any web page and get an inline answer with the reasoning laid out, without leaving the tab.
Generates decks automatically from your notes, slides or PDFs and schedules reviews so cards you keep missing resurface sooner; imports existing Anki and Quizlet decks.
Turns any material or topic into a practice quiz, grades each answer immediately and explains why it was right or wrong, then leans the next quiz into your weak spots.
Converts a topic or a long reading into an editable, interactive map of branches and relationships, useful for getting the shape of a subject before memorising details.

提供巨大的上下文窗口与深度的 Google 生态系整合,但对于纯推理任务感觉较不够专精。
