Knowt
AI flashcards, notes and quizzes built from your own study material
About Knowt
Knowt is a study app that takes the material you already have - a lecture PDF, a slide deck, a recording of a class - and turns it into the things you actually revise from: flashcards, study guides, practice quizzes and a voice tutor that asks you questions out loud. The problem it solves is the gap between having notes and being ready for an exam. Most students lose hours retyping a reading into flashcards before any revision begins, and Knowt removes that step by generating the deck from the source document.
It is worth being clear about what Knowt is. The company markets it as a free Quizlet alternative, and the free tier is exactly that: a complete flashcard and notes app, with spaced repetition, practice tests and matching games, that does not ask for a card. The AI layer sits on top and mostly sits in the paid tier. Knowt states 8.7 million users on its own homepage and a 4.8 rating across more than 6,200 reviews, which makes it the most widely used product in this part of the directory. It covers school, college and standardised test preparation rather than professional training.
You start by adding a source: upload a PDF or slide deck, paste a link, import an existing Quizlet set, or record a lecture in the app. Knowt reads it and produces a set of flashcards and a summarised study guide from the content, which you can edit before studying. From there you choose how to revise. Spaced repetition schedules the cards you keep getting wrong, practice tests generate exam-style questions from the same material, and matching and learn modes give you a different angle on the same deck. The voice tutor turns the deck into a spoken back-and-forth, asking questions and responding to what you say, which is closer to being quizzed by a friend than to reading a screen. Teachers can create classes, assign sets and see how a class is performing on each topic.
- •Generation From Your Own Material - Flashcards, study guides and quizzes built from a PDF, a slide deck, a link or a recorded lecture rather than typed by hand
- •Spaced Repetition and Practice Tests - Scheduling that prioritises the cards you get wrong, plus exam-style question sets generated from the same source
- •Voice Tutor - A spoken tutor that asks you questions and reacts to your answers, for revision away from a keyboard
- •Lecture Capture - Record a class in the app and get a summary and a deck from the recording
- •Quizlet Import - Bring existing sets across instead of rebuilding them
- •Teacher Classes - Assign sets to a class and see per-topic performance across students
School and university students who revise from their own lecture material and want the mechanical part of making flashcards done for them, and teachers who want to assign and track practice sets. It fits standardised test preparation well, since the question generation works from a syllabus document as readily as from lecture notes. It is not a developer tool and makes no claim to be. If you want the generative features - the lecture summariser, the podcast output, the voice tutor - you are looking at $24.99 a month, which is dear next to most of this category, and the honest summary is that the free tier is a very good flashcard app while the AI is the thing you pay for.
