What our research says

Quizlet

Quizlet is still the default for exam-cramming flashcards because the library is enormous and the free tier covers set creation and the main study modes; the AI additions are convenient rather than essential. Pay for Plus if you hate ads or want the generated practice tests, but if you care about long-term retention, Anki's free spaced repetition remains the stronger tool.

Pros

Largest public library of study sets, searchable by course and textbook
Set creation, Learn, Test and Match modes are free, with ads
Plus is free for verified teachers, and school licences exist
Web, iOS and Android apps with offline study on mobile

Cons

Free tier shows ads and holds back the AI practice tests and explanations
Site and apps have moved features in and out of the paywall repeatedly, so older advice is unreliable
Annual plan auto-renews after the 7-day trial and the monthly plan has no trial
No public API for building on the set library

Seekh.co

Seekh's job is converting existing study material a user already has, such as a PDF, a lecture video, or an article, into practice quizzes and flashcards rather than starting from a blank deck built by hand. Because its own site was hard to read directly during this research, the pricing figures here are approximate and worth double-checking before subscribing.

Pros

Generates quizzes and flashcards directly from a PDF, URL, or YouTube link
Progress tracking flags which topics need more review
Founded in 2020, suggesting more operating history than many newer entrants in this batch
Free tier available to try before paying

Cons

The vendor's own site gave little readable detail during this research, so pricing here is approximate
No mobile app was confirmed, only a web platform
