How to choose

Choose based on your inputs and workflow: if most of your content lives in PDFs, pick a tool that ingests PDFs and generates flashcards/quizzes automatically. If you already have decks, pure SRS tools can suffice.

Also look at export, privacy, and collaboration. Test quiz quality and whether the tool supports spaced repetition. AI helpers should reduce manual copy-paste.
