Quizlet is still the biggest flashcard app, with spaced repetition and over 700 million shared sets, but Quizlet Plus ($7.99 a month or $35.99 a year) caps you at 20 rounds of Learn and 3 practice tests a month, and only Plus Unlimited ($9.99 or $44.99) removes the caps. The best free Quizlet alternatives are Knowt, which has free Learn mode and spaced repetition and imports Quizlet sets, and Anki, which is free on computers and Android. If you study from your own slides, PDFs and YouTube lectures and also want a real chatbot, Zemith Plus ($15.99/mo) makes flashcards, quizzes and podcasts from up to 50 sources per project next to Claude, GPT, Gemini and Grok, though it has no spaced repetition.

“Spaced Repetition helps you review flashcards based on how well you remember them. After reviewing each card, you rate your recall, and Quizlet uses your response to determine when to show the card again.”Quizlet Help Center, Official help article, Checked 14 Nov 2026

For students who study from slides, PDFs and YouTube lectures and also use a chatbot, Zemith Plus ($15.99/month) is the best value: its Library makes flashcards, quizzes, podcasts and mind maps from up to 50 sources per project, and the same plan includes Claude, GPT, Gemini and Grok. If you only want to memorize existing decks, Knowt and Anki are the closest free replacements.
Yes. Knowt's free plan includes unlimited Learn mode, spaced repetition and practice tests, and it imports Quizlet sets in two clicks through its browser extension. Anki is free on Windows, Mac, Linux and Android with free sync; its iPhone app costs $24.99 once. Gemini Notebook makes flashcards from your sources for free within daily limits. Zemith's Free plan is chat only.
Anki is built around it, Knowt includes it for free, and Gizmo lists it on its App Store page. Quizlet itself has spaced repetition on its website. Zemith does not schedule reviews: it tracks which cards you got and which you are still learning within a study session.
Not directly: Zemith has no Quizlet importer. Knowt and Gizmo can import Quizlet sets. On Zemith you make new decks from the source material itself, such as the lecture PDF, slides or YouTube video, with the AI Flashcard Generator or a Library project.
Yes, if flashcards are the only thing you pay for: Quizlet Plus Unlimited is $44.99 a year against $179.88 for Zemith Plus. If you also pay $20 a month for ChatGPT Plus or Claude Pro, the pair costs $284.99 a year, and Zemith Plus covers both for $179.88.
Yes, on Plus and Professional. Chats on that provider's models bill to your provider account and use no Zemith credits; tools and Library outputs such as flashcards and quizzes still use credits. A key also unlocks that provider's top models, such as Claude Opus on Plus.
