Memo AI (memo.cards) is a polished AI flashcards workspace with spaced-repetition review and several other study tools around it. StudyPDF is built around your whole course: cited answers, one connected concept map, real graded exams, and tracked mastery. The App Store app MemoCards: AI flashcards comes from a different developer and is not covered here.

On this page, MemoCards AI means Memo AI at memo.cards, the AI flashcards and study workspace formerly called PDF2Anki. The App Store app MemoCards: AI flashcards is a separate product from a different developer, and this comparison does not cover it. Check the developer name before you install or sign up.
Yes, if you want a tool built around your whole course rather than one deck at a time, with full graded exams, per-concept mastery tracking, study guides and cheat sheets, and answers cited to the page. Both make AI flashcards from your files, support spaced repetition, and export to Anki (StudyPDF on Pro and up). StudyPDF goes deeper on connecting and tracking your whole course.
It maps your whole course into one connected concept graph, writes full graded practice exams with sections and a pass mark, tracks per-concept mastery so it knows what to study next, builds study guides and cheat sheets, and refuses to answer when something is not in your material instead of guessing.
Memo AI offers a dedicated spaced-repetition review with many card styles, lets you pick the AI model in its chat where a selector is offered, and turns notes into audio podcasts and infographics.
It is free to start, and Free gives you about 4 materials a week. Pro and Ultra add a bigger weekly pool of credits for heavier exam-season use. You only upgrade when you outgrow the free plan.
Upload your course and ask Bo anything. No card required.
