A set usually takes less than a minute. All the AI tools share one daily limit on AI generations - you can see how many you have left under the text box.
Language models make mistakes and can state something false with complete confidence - these are called hallucinations. Our two checks catch some of these errors, but not all of them: a quote can be genuine while the answer on the card still gets it wrong. The AI also works only from your text, so if your notes contain a mistake, it will end up on the cards too. That’s why it’s worth going through the set with your text at hand - the quote next to each answer makes this quick.
When you recall an answer - on a flashcard or in a quiz - you remember it better than when you read the same text again. This is called the testing effect, and studying this way is called retrieval practice. Rereading, on the other hand, can make you feel you know the material simply because the text looks familiar.
Cards you mark “Not yet” go to the back of the deck and keep coming back until you know them all. You’ll get the most out of a set, though, by reviewing it over several days rather than in one sitting, with gaps you can gradually lengthen. Our guide to spaced repetition shows how to plan this.
