Pricing Model
FreemiumQuizlet is freemium. The official site confirms a free tier and a paid Quizlet Plus plan that adds practice tests, study guides, Learn mode and expert solutions with monthly usage limits, available annually or monthly with auto-renewal. Its pages in the content we could read did not show dollar amounts. A comparison blog published July 2026 by a competing study app reports Quizlet Plus at $7.99 per month or $35.99 per year (about $2.99 per month), and Plus Unlimited at $44.99 per year with no daily caps. Treat these as unofficial and confirm on quizlet.com/upgrade before buying. On the free tier, the same source says Learn and test modes are capped at a limited number of rounds per day that reset every 24 hours, while flashcard creation, browsing public sets, Match and Quizlet Live remain free. The free version shows ads, which Plus removes.
FreemiumCaktus AI offers a free tier with limited access. To unlock unlimited access to all 25+ AI tools, longer outputs, and premium features like real academic citations and document uploads, a subscription is required. Flexible subscription plans are available.
