StudyCards AI

StudyCards AI turns a PDF into a ready-to-study flashcard deck. Upload lecture slides, a textbook chapter, or a study guide, and it generates question-and-answer and cloze-deletion cards, then schedules them with spaced repetition. We analyzed 18,217 real reviews from 667 students to work out what actually helps people learn. Three findings shaped the product: Accuracy on the same card climbs from 69.0% on the first attempt to 97.7% by the fourth repeat. Sessions on decks of 50+ cards get completed only 7.8% of the time, versus 25.0% for decks of 10 cards or fewer. So we keep generated decks small. Students' own easy/medium/hard ratings track real accuracy almost exactly: 95.1%, 72.3%, and 47.4% correct. Free to start. Export to Anki.
