Knowt
Knowt is a study app for the web, iPhone and Android, with flashcards, AI notes and exam prep. It offers the same kind of study modes as Quizlet, including spaced repetition, free on your own sets. It can also import Quizlet sets.
Which platforms does Knowt run on?
Knowt runs in a browser and on iPhone, iPad and Android. Your sets and notes sync between the website and the apps. There is no desktop app, but a Chrome extension imports Quizlet sets and makes notes from PDFs and YouTube videos. Offline use is not documented.

| Web | Works in Chrome, Firefox, Safari and Edge. A Chrome extension imports Quizlet sets. |

Does Knowt use spaced repetition?
Yes, as one of several study modes, on the website and in the apps. In Spaced Repetition mode, you rate each card Again, Hard, Good or Easy. Cards you find hard come back sooner, and new cards are added each day. You can set the number of new cards and adjust each button’s interval. Knowt does not say which algorithm it uses.
What cards can you make in Knowt?
A Knowt card has a term and a definition. Each card can have an image, audio, custom multiple-choice options and hints. AI can make cards from a prompt, PDFs, slides, videos or lecture recordings. Cloze cards and maths formatting are not documented. You can import Quizlet sets, or paste cards exported from Anki or a spreadsheet.

Our review
Knowt is a study app in the style of Quizlet that gives more away for free. All its study modes, spaced repetition included, are free on your own sets, and Quizlet sets can be imported in a few clicks.
Spaced repetition is one mode among many rather than the centre of the app. Knowt does not explain its algorithm, the free plan shows ads, and much of its AI and exam prep needs a subscription.
It suits students who want varied practice before a test. For long-term memorisation over months, an app built around spaced repetition gives more control over your reviews.
