The best AI flashcard generators
The best AI flashcard generator depends on where your material comes from. Recall lets Claude or ChatGPT build your decks for you. RemNote and Knowt turn PDFs, slides and lectures into cards, and Quizlet turns class notes into study sets.
In short
- Recall lets an AI assistant create and fix your cards, and AI fills in answers, translations and audio.
- RemNote and Knowt generate cards from documents and lectures; most of that AI needs a subscription.
- Quizlet creates study sets and practice tests from notes; Mochi fills language cards with AI.
- AI saves time, but check generated cards before you study them.

- Reviewed with its own algorithm or FSRS
Limits
- Small AI allowance on the free plan

How should you use AI flashcards?
Use AI to save typing, then check every card before you study it. Generated cards can contain errors, and they can test details that don’t matter to you.
- Keep cards small. One fact per card is easier to remember than a paragraph.
- Ask real questions. Each card should make you answer from memory, which is what makes active recall work.
- Review them with spaced repetition. Making cards is only the start: spaced repetition is what helps you remember them.
How did we choose these apps?
We selected five flashcard apps that use AI to make or fill in cards, each suiting a different source of material. Every fact comes from our app profiles, which are checked against each app’s official website, documentation and store listings.
Which other apps did we consider?
Anki has no built-in AI; some add-ons add it, and you can import cards written by ChatGPT or Claude. SuperMemo’s AI explains text while you read on Windows, and its app offers AI conversations for language courses, but neither generates cards from your material.
Frequently asked questions
Can ChatGPT or Claude make flashcards?
Yes. Either can write questions and answers that you copy into a flashcard app, for example as a list you import into Anki. Recall’s connectors go further: the assistant adds the cards to your decks directly.
Are AI-generated flashcards as good as your own?
Not always. Writing cards yourself makes you process the material, and AI can include errors or cards that test the wrong thing. It is worth checking and editing generated cards before you study them.
Which AI flashcard app is free?
All five have a free plan with a small AI allowance. Recall gives 200 AI Autofill uses a month, Mochi 5,000 AI tokens, and RemNote 5 card generations. Larger amounts need a subscription.
