Knowt

Knowt is an AI study app that turns class notes, PDFs, slides and videos into flashcards, practice tests and study guides for high school and college students. Its pitch is simple: the studying itself stays free. Flashcards, learn mode, spaced repetition and practice tests do not sit behind a paywall, while the paid tier is reserved for heavier AI work like summarizing lectures and long files. That positioning has made it a popular switch for students frustrated with paywalls elsewhere.

What is Knowt used for?

Students use Knowt to build a study set from their own course material in minutes and then drill it until exam day. It also hosts a large library of sets made by other students.

• Uploading PDFs, PowerPoints, images, spreadsheets or YouTube links and getting notes and flashcards back
• Recording a live lecture and turning it into notes, flashcards and practice questions
• Studying with learn mode, spaced repetition, matching and sorting games
• Importing existing Quizlet sets, Kahoot games and Wayground quizzes with the Chrome extension
• Preparing for AP, SAT and ACT exams with practice tests and mock exams
• Asking Kai, the AI study helper, to quiz you by voice or explain a missed question

Who Knowt is best for

Knowt is a strong fit for high school students preparing for AP exams and college admissions tests, and for college students who rely on flashcards and want to stop paying for basic study modes. It also suits anyone with a large Quizlet library they want to move. Teachers and schools have separate plans. Learners who mainly want a conversational tutor for deep explanations may prefer a chat based tool.

Knowt pricing

As of October 2026, Knowt's plans page lists a free Basic plan with unlimited file creation, live collaboration and storage, plus access to a library of 5 million resources. The Ultra plan costs $12.99 per month when billed upfront at $149.99 per year, with a 3-day free trial, or $24.99 per month on monthly billing. Ultra adds an ad-free experience, AI summarizers for PDFs, videos, images and PowerPoints, the AI lecture recording summarizer, an AI podcast generator, the AI voice tutor on all files, and full AP, SAT and ACT prep. Teacher and school pricing is listed on separate pages.

Limitations to keep in mind

• The free plan shows ads, and the strongest AI features need Ultra
• Monthly Ultra billing costs nearly twice the effective annual rate
• AI generated cards should be checked against your class notes, since summaries can miss details your teacher emphasized
• Shared community sets vary in quality

Knowt vs alternatives

Quizlet has the largest library of existing study sets and brand recognition with teachers, so it is the safer choice if your class already shares Quizlet sets. Unstuck AI focuses more on turning course material into guided study help across many file types. Gemini Notebook is better for deep question answering over long documents, though it is not built around flashcard drills. Knowt wins for students who want free spaced repetition and practice tests, an easy Quizlet import, and test prep for AP and admissions exams in one place.

Tips for getting started with Knowt

Install the Chrome extension first and import your existing Quizlet sets so you do not start from scratch. When uploading lecture slides, split long decks by topic so the generated flashcards stay focused. Use spaced repetition for the weeks before an exam and switch to practice tests in the final days to find weak spots.
