The Forgetting Curve

Cognitive science is unambiguous: without spaced review, you forget most of what you learn within days. Flashcards with spaced repetition are the countermeasure - but building cards by hand is slow, and most students give up before the system pays off. AI generators remove the bottleneck: paste your notes, get well-formed cards, and let the scheduler handle when to review them.

1. Anki (free, open source, 29.8k GitHub stars)

The gold standard for spaced repetition. Not AI - the scheduler is the science. Pair it with any AI card generator: Anki handles when you review, AI handles what is on the cards. Free on desktop; the official iOS app is paid, Android is free.

2. ChatGPT (free tier)

The most flexible generator: paste your notes or textbook section and ask for cloze-deletion cards, Q&A cards or concept-definition pairs in Anki's format. You can even have it generate cards from a photo of handwritten notes.

3. Knowt (free tier, paid plans)

Purpose-built: upload notes or lecture slides, and it generates flashcards plus practice quizzes. The free tier is generous, and the import-from-notes workflow is the smoothest on this list.

4. Quizlet (free tier, Plus around $3-8/mo)

The familiar choice: AI-generated cards from your notes, plus the study modes (learn, test, match) students already know. Free tier is usable; Plus adds the AI generation limits lifted.

5. RemNote (free tier, paid plans)

Notes and flashcards in one: highlight a phrase while taking notes and it becomes a card automatically. Built for the medical students and polyglots who live in their notes.

6. Claude (free tier)

Excellent at turning dense material - lecture transcripts, textbook chapters - into well-worded cards with precise definitions. Often produces better card wording than ChatGPT for technical subjects.

Bottom Line

Anki for the scheduler, ChatGPT or Knowt for the card generation. The study rule from the research: review cards the day you make them, then at increasing intervals - and active recall beats re-reading every time. AI makes the cards; only you can do the recalling.
