Knowt grew quickly as a free Quizlet alternative and has since become a broad AI study suite: notes, AI summaries, lecture tools and flashcards with several study modes. Space Repeat does one thing: it schedules the cards you write so you remember them long term. Here's how the two compare.

Knowt is the better fit if you want an all-in-one AI study tool that turns notes and lectures into material for you, and it has a generous free plan. Space Repeat is the better fit if your goal is long-term retention: spaced repetition runs every review rather than being one mode among several, and you build the cards yourself, which is part of what makes them stick.

You want AI to turn your notes and lectures into flashcards and summaries for you, or you rely on a large library of public study sets.
Knowt has a free Basic plan that includes flashcard creation and its study modes. Its Ultra plan adds AI summarizers, lecture recording tools and an AI tutor, and was listed at $149.99 per year or $24.99 per month at the time of writing. Space Repeat is free while it's in beta.
No, on purpose. Writing a card in your own words is the first round of learning the material, and it keeps every card focused on what you actually need to know. We explain the reasoning in our article on AI flashcards versus making your own.
Yes, Knowt offers a spaced repetition mode alongside Learn mode, practice tests and matching games. In Space Repeat, spaced repetition isn't a mode you pick: every review is scheduled by it, so cards come back right before you'd forget them.
Space Repeat imports cards from a CSV file or from pasted text, so any set you can copy out of Knowt as term and definition pairs can come with you as a new deck.

Why Space Repeat Doesn't Use AI to Generate Your Flashcards
Plenty of flashcard apps now let AI scan your notes and generate cards for you automatically. It sounds convenient. It also skips the one step that makes flashcards work in the first place: understanding the material yourself.
