Best for: free AI flashcards from your own notes and slides
Knowt's AI flashcard maker turns uploaded notes, PDFs, images, PowerPoints, videos and audio into flashcards, and Knowt says making flashcards with it is free. You can edit and rearrange every card, then study with free modes like Learn mode and practice tests. The paid Ultra plan ($24.99/month, or $95.99 billed annually) adds ad-free studying plus AI summaries of PDFs, videos and lecture recordings.
Why students use it:
Best for: a familiar app with a huge shared library
Quizlet is the flashcard app many students already know, with study modes like Learn, Test and Match and a large library of sets made by other users. Its AI tools can help turn your notes into study sets, but the free plan shows ads and limits some study modes, and most AI features require a paid Quizlet Plus subscription. Quizlet Plus is listed at $19.99 per year on Quizlet's upgrade page.
Why students use it:
Choose Knowt if you want to turn your own notes, slides and recordings into flashcards and practice tests for free. Choose Quizlet if you like its study modes and shared library and don't mind paying for Quizlet Plus to unlock its AI features. Either way, check AI-generated and shared cards against your course materials.
Making flashcards for your own studying is generally fine, but don't upload or publicly share exams, quizzes or restricted course materials. Shared sets can contain errors, so check them against your notes.
