Knowt

Knowt is a student-focused study platform that turns lectures, PDFs, slides, videos and notes into flashcards, quizzes and study guides, with AP, IB, ACT and SAT exam prep, positioned as a free Quizlet alternative.

Knowt is a study platform that combines flashcards, note-taking and AI-generated study material in one account. It positions itself as an alternative to Quizlet, and its homepage claims several million users across schools and universities. The core idea is to take whatever raw material a student already has, such as a recorded lecture, a long PDF, a slide deck, a YouTube video or a pile of messy notes, and turn it into material that supports active recall. In practice, the tool is organized around a few entry points. A lecture notetaker records a class and produces detailed notes along with flashcards, quizzes and games. Separate summarizers handle PDFs, PowerPoint files and videos, converting long readings into study guides or interactive review sessions. A flashcard maker builds decks automatically, and a learn mode is offered without a limit on the free tier according to the site. A voice feature called Kai can quiz a student out loud or produce a podcast from uploaded material. Public libraries of notes and flashcards created by other users give learners something to start from when a topic is already covered. Exam preparation is a distinct area. Pages exist for AP and IB exams, with practice test rooms, free-response practice and a score calculator, and the homepage also mentions ACT and SAT prep with personalized schedules, mock exams and analytics. Apps are available for iOS and Android, and the service also runs in the browser. The audience is mainly high school and college students, with teachers also named among its users. Compared with older flashcard services, the pitch is breadth: instead of only storing cards, it generates them from source material and adds recorded-lecture and exam tools around them. Anyone wanting a narrowly focused spaced-repetition engine with deep scheduling controls may find it more consumer-oriented, while students who want one place for notes, cards and test practice have a fairly complete option here.
