Quizlet
Quizlet is a flashcard and study app for the web, iPhone and Android, known for its huge library of shared sets, its study games and its classroom tools. Since 2026 its Flashcards mode on the website offers optional spaced repetition; its other modes quiz you within a session rather than schedule reviews.
Is Quizlet free?
Partly. You can create sets, study with Flashcards and play the games for free, with ads. Learn, Test, Practice Tests and AI study guides are limited on the free plan, and full access needs Quizlet Plus (US$35.99 a year or US$7.99 a month) or Plus Unlimited (US$44.99 a year or US$9.99 a month). Students in a teacher’s class get Learn and Test free for that class’s sets.
Which platforms does Quizlet run on?
Quizlet runs in a web browser and has apps for iPhone, iPad and Android; there is no desktop app for Windows, Mac or Linux. Your sets are stored in your Quizlet account, so they are the same on every device. Studying offline works only in the mobile apps, for Flashcards and Match.

Does Quizlet use spaced repetition?
Yes, since August 2026, but only as an option on the website. In Flashcards, you can choose the spaced repetition method: you rate each card Repeat, Hard, Okay or Easy, and Quizlet decides when to show it again, from a few minutes to several days later. It is not yet in the mobile apps, Quizlet does not say which algorithm it uses, and the other modes, such as Learn and Test, only quiz you within a session. The confusion has a history: Quizlet offered spaced repetition from 2015 with Long-Term Learning, dropped it around 2020 because most students study a set over only a few days, and kept using the term in its marketing in the years without it.
- Grading
- In spaced repetition: four buttons, Repeat, Hard, Okay and Easy. In basic Flashcards, an optional Know / Still learning sort. In Learn and Test, answers are marked right or wrong.
- Settings
- Few settings: the number of new cards per day, switching study method, and a daily reminder at 10 a.m. that can be turned off. No control over intervals or a target retention.
- Statistics
- Progress (subscribers) groups a set’s terms into Not studied, Still learning and Mastered across activities; teachers get Class Progress. No review history or forecast graphs are documented.
What cards can you make in Quizlet?
A Quizlet set is a list of terms and definitions, or questions and answers, and each card has two sides. Cards can include text-to-speech audio and images from a free gallery; your own images and audio recordings, diagram sets and text formatting need Quizlet Plus. AI tools can turn notes, files or recorded lectures into sets and study guides.
- Shared decks
- Sets are public by default and searchable; Quizlet says there are millions. Teachers can share sets with classes.
- Import
- Pasted text, with terms and definitions separated by a comma, tab or dash (on the website only); scanning a document; AI generation from notes and files. No Anki import.
- Export
- Your own sets as plain text you copy (web only, no images), and printing. Sets copied from others can’t be exported.
- Add-ons and integrations
- No public API: Quizlet stopped issuing API keys in December 2018. Official apps in ChatGPT and Claude can create Quizlet sets.

Our review
Quizlet is one of the best-known study apps among students. It is easy to start with: making a set takes minutes, and someone has often already shared a set for your course or textbook. Its range of activities, from Learn and Test to games such as Match and Blast, makes revision varied, and its classes and live games make it a common tool in classrooms.
Quizlet was designed mainly to help students prepare for a test, not to schedule reviews over months. Its adaptive Learn mode chooses questions well within a session, but only the new spaced repetition method in Flashcards spaces reviews across days, and it is web-only, with an algorithm that is not published and few settings. Much of the app now sits behind a subscription with monthly limits, and the free plan shows ads. Shared sets vary in accuracy, so it is worth checking a set before relying on it.
Quizlet suits students who want ready-made sets and engaging practice before an exam, and teachers who run classes. For long-term memorisation, such as a language or medical school, an app built around spaced repetition will give you more control over your reviews.
