Best for: serious long-term memorization with spaced repetition
Anki is a free, open-source spaced-repetition flashcard app for desktop, with a free Android version (AnkiDroid) and a paid iPhone app (AnkiMobile). Recent versions include the FSRS scheduling algorithm. Anki has no built-in AI card generator, but many students ask a chatbot to draft question-and-answer pairs from their notes and import them as a text file.
Why students use it:
Best for: easy studying with shared sets and multiple modes
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 Quizlet if you want something simple to start with, like its study modes and shared sets, and don't need heavy customization. Choose Anki if you're memorizing a lot of material over months — for example in medicine, nursing, law or languages — and want powerful free spaced repetition. Many students make cards with AI help, check them, then study in Anki.
Flashcards for your own studying are generally fine, but don't upload or share real exams or restricted course materials, and check shared or AI-made cards against your course materials.
