Who Knowt is best for
Students recording lectures
The AI lecture summarizer records a class and produces notes, flashcards, tests and games, so one recording can become several study formats. The summarizer is described as part of Ultra's AI tools.
Test-prep students
Ultra includes full AP, SAT and ACT prep, which gives a high school student a structured track alongside their own cards.
Learners who like talking through material
The Kai voice tutor quizzes you aloud on uploaded files, which suits people who revise on a commute or while walking.

What Knowt does
- AI lecture summarizer
- Records a lecture and creates notes, flashcards, tests and games from it, which suits students who would rather capture a class than type notes during it, and who then want cards made from the transcript.
- Kai voice tutor
- A spoken tutor that quizzes you on the files you upload, included on Ultra for all files, which suits learners who revise aloud. The vendor pages do not give languages or session limits.
- Document summarizers
- AI tools for PDFs, video, images and PowerPoint produce summaries and study material from course files on the Ultra plan, so a student can drop in a slide deck or a textbook chapter and get a summary plus study material.
- Exam predictor and study plan
- Knowt describes an exam predictor and a study plan built from class files, aimed at planning review time before a test, so a student can see what to study first from files already uploaded.
- Apps and Chrome extension
- Mobile apps on the App Store and Google Play and a Chrome extension let you study and capture material away from the web app, for example while clipping material from a page or reviewing on a phone between classes.
How Knowt handles your data
Knowt's privacy policy says it keeps data as long as needed to provide the services and then as the policy describes. It says Google user data is not used to train generalized AI models. For Knowt's own AI features, the pages we read do not state whether uploaded material trains models. It says data may be stored and processed in the user's country or other countries where Knowt or its group companies operate, with no specific region and no certification named. Payments run through Stripe, per the policy.
Where Knowt falls short in practice
- Annual billing carries the price. The $7.99 figure only applies if you pay $95.99 upfront; month to month costs $24.99, so a one-semester user pays far more per month, and the upfront charge is the cost to compare with other apps.
- AI sits behind Ultra. The voice tutor, AI summarizers and AP, SAT and ACT prep are on Ultra, so the free tier is flashcards and learn mode with ads.
- Training position for uploads is open. The privacy policy addresses Google user data but not Knowt's own AI, so a school with a strict policy has to ask the vendor directly.

How much is Knowt Ultra?
As of November 2026, Ultra Annual is $7.99 a month, billed upfront as $95.99. Ultra Monthly is $24.99 a month. Both include the AI summarizers, the voice tutor and full AP, SAT and ACT prep. Teachers and schools have separate plans with bulk pricing that the plans page does not list.
Is Knowt free?
Partly. The free plan includes flashcards and unlimited learn mode and is supported by ads. Ultra removes the ads and adds the AI summarizers and voice tutor. The plans page does not give a limit on how many free flashcards you can create, so check the app when you sign up.
What does the Kai voice tutor do?
Kai is a voice tutor that quizzes you on your uploaded study materials, and it is included on Ultra for all files. The vendor pages describe it as a spoken quiz companion, but they do not give details on languages or session length. Try it in the free trial of the app if one is offered.
Can Knowt make flashcards from a lecture recording?
Yes, according to the vendor. The AI lecture summarizer records a lecture and creates notes, flashcards, tests and games from it. The plans page places AI summarizers for PDFs, video, images and PowerPoint on Ultra, so check which plan covers lecture recording before you rely on it in class.
Does Knowt use my files to train AI?
The privacy policy states that Google user data is not used to train generalized AI models. For files you upload to Knowt's own AI features, the pages we read do not state a position. Ask the vendor in writing if your institution requires a no-training guarantee before uploading coursework.
