8 Best Knowt Alternatives in 2026
Apps like Knowt for AI flashcards and quizzes, ranked on what the free plan gives you, price, AI from your own files and spaced repetition. Plus: is Knowt free, and is it better than Quizlet?
Knowt keeps its study modes free, but its free plan summarizes only one PDF, video, slide deck or lecture recording a month, and Ultra costs $24.99 a month. These 8 apps cover the same ground in different ways — here's what each one gives you for free.
The best Knowt alternative in 2026 is StudyGlen. It turns a PDF, a photo of your notes or a YouTube video into flashcards and a quiz, and schedules every review with FSRS-6 by default. Knowt's free plan summarizes one file a month; StudyGlen generates one AI deck or quiz from your files every day, free, and paid credits never expire.
StudyGlen is the best Knowt alternative if you want the deck made for you: it builds flashcards and a quiz from a PDF, a photo of your notes or a YouTube video, schedules every review with FSRS-6 by default and adds AI images where a visual helps — one AI deck or quiz a day free, and paid credits never expire. Quizlet is the pick if you want the biggest platform and its library of shared sets. Anki is free, open source and the most configurable. Gemini Notebook (formerly NotebookLM) makes free flashcards and quizzes from your sources but does not schedule reviews, and Gizmo turns your Quizlet and Anki decks into a game.

Is Knowt free? What its free plan gives you in 2026
Yes — studying on Knowt is free. A free account gets unlimited flashcard sets and notes, millions of public sets, and every study mode on your own sets: Learn, Practice Test, Spaced Repetition, Match and Knowt Play. Its Spaced Repetition mode uses Again, Hard, Good and Easy ratings with intervals you can adjust; Knowt does not name the algorithm behind it.
The limits are on AI. The free plan includes 1 AI summary a month of a PDF, image, video, PowerPoint or lecture recording, 1 full-length AP, SAT or ACT mock exam and 5 practice-room sessions, and it shows ads. Knowt Ultra removes the ads and the AI limits for $24.99 a month or $149.99 a year, according to Knowt's help center and the US App Store; prices can differ by country, so check before you buy.
So people look for a Knowt alternative for one of three reasons: they want more AI generation from their own files than one summary a month, a published scheduler such as FSRS, or an app built around one job — an AI tutor, a game or years of memorization. The apps above each solve at least one of those.
Knowt vs Quizlet: which one is better?
For free studying, Knowt usually wins. It imports your Quizlet sets, keeps Learn, Practice Test, Match and Spaced Repetition free on your own sets — including unlimited Learn rounds — and has its own library of public sets, notes and AP exam guides. The catch is AI: one free summary a month, and ads.
Quizlet is the bigger platform, with over 60 million learners by its own count. Its AI turns your notes or a lecture recording into a study guide and flashcards, and it adds practice tests, podcasts and spaced repetition. But Learn rounds, practice tests and AI are limited on its free plan. Quizlet Plus costs $9.99 a month or $44.99 a year on the US App Store — less than Knowt Ultra at $24.99 a month or $149.99 a year.
Neither names its spaced-repetition algorithm. If you want the deck made for you every day and scheduled with a published algorithm, StudyGlen generates one AI deck or quiz a day free from a PDF, a photo or a YouTube video, schedules it with FSRS-6, and sells pay-once credits that never expire.

Frequently Asked Questions
What is the best alternative to Knowt?
StudyGlen is the best Knowt alternative for AI flashcards and quizzes. It builds a deck and a quiz from a PDF, a photo of your notes or a YouTube video — half of all decks are ready in about 30 seconds — and schedules reviews with FSRS-6 by default. The free plan gives one AI deck or quiz a day, and paid credit packs start at $4.99 and never expire. Quizlet is the pick for shared sets, and Anki for free long-term memorization.
Is there a free alternative to Knowt?
Yes. Anki is completely free on Windows, Mac, Linux, Android and the web, with FSRS as an option, but it has no built-in AI. Gemini Notebook (formerly NotebookLM) makes free flashcards and quizzes from your PDFs, websites and YouTube videos, though it does not schedule reviews. StudyGlen gives a free account one AI deck or quiz a day from your own files, with FSRS-6 spaced repetition and unlimited review.
Is Knowt free?
Yes. Knowt's free plan includes unlimited sets and notes and every study mode on your own sets, including Learn, Practice Test and Spaced Repetition, with ads. AI is limited: 1 AI summary a month of a PDF, image, video, PowerPoint or recording, 1 free AP, SAT or ACT mock exam and 5 practice-room sessions. Knowt Ultra removes the limits for $24.99 a month or $149.99 a year, according to its help center.
Is Knowt better than Quizlet?
For free studying, usually yes: Knowt imports Quizlet sets and keeps Learn, Practice Test and Spaced Repetition free, including unlimited Learn rounds, while Quizlet limits Learn rounds and practice tests on its free plan. Quizlet is the bigger platform, with over 60 million learners by its own count, and Quizlet Plus ($44.99 a year on the US App Store) costs less than Knowt Ultra ($149.99 a year). Neither names its spaced-repetition algorithm.
Which Knowt alternative has the best spaced repetition?
StudyGlen uses FSRS-6 by default — the scheduler that predicts recall more accurately than SM-2 in the open benchmark of about 727 million Anki reviews. Anki offers FSRS as an option and RemNote as an opt-in beta, with SM-2 as the default in both. Brainscape uses its own confidence-based system. Knowt, Quizlet, Gizmo and StudyFetch do not name their algorithm, and Gemini Notebook does not schedule reviews.
Can I move my Knowt flashcards to another app?
Yes. Knowt's help center describes exporting a set as a PDF, so the simplest route is to copy your terms into a CSV file. StudyGlen imports CSV, TSV and TXT files as well as Anki .apkg and .colpkg decks, and converts Anki review history to FSRS so cards you have already learned don't reset. Importing is free with an account, up to 20 decks a day.
