Knowt vs Quizlet: Free Tiers, Limits and Fit
By Mark Fulton · 2026-10-01 · 11 min read
Knowt is better than Quizlet if your problem is the paywall on study modes: it advertises unlimited Learn mode and unlimited practice tests on its free plan, and it puts its paid line around AI tools and exam prep instead. Quizlet is better if you want the biggest library of sets other people already wrote and you are happy to study within a free tier that has monthly limits. As of October 2026, Knowt's free plan is Basic at $0, and its paid Ultra plan is $149.99 billed up front for the year or $24.99 month to month. Neither one lets you skip the signup entirely if you want to save your own cards. If you only want to drill a deck right now, a no-account player beats both.
That is the short answer. The rest is the part comparison pages tend to skip: what "free" means on each side, what sits behind the paid plans, whether your old Quizlet sets come across, and which one fits a class set versus solo revision. Where I could read a vendor's own page this month I quote it. Where I could not, I say so instead of repeating a number I have not seen.
What does Knowt do that Quizlet doesn't?
Knowt's pitch is stated plainly on its homepage: create, share and study for free with unlimited Learn mode. It also says that Quizlet limits access to test mode while Knowt lets students take as many AI-generated practice tests as they want. That is a marketing claim from a competitor, so treat it as Knowt's position rather than a measurement, but it points at the real difference between the two tools.
The difference is where each one draws the line between free and paid.
- Knowt keeps the study loop open on the free plan (flashcards, Learn mode, practice tests) and charges for the heavier AI tools: summarizers for PDFs, video, images and slides, a lecture recording summarizer, a podcast generator, a voice tutor, and full access to AP, SAT and ACT prep.
- Quizlet built its name on the study loop itself, and over the last couple of years the adaptive modes, Learn and Test, moved toward being subscriber features, with a limited taste on the free account. Our separate breakdown of what Quizlet Plus costs and what the free plan still does has the details I checked in September.
Two other differences matter in practice. Knowt lists a library of millions of public resources that you can browse, and Quizlet's public library is also very large, so on raw content they are closer than either would like you to think. And Knowt leans toward turning your own notes, slides and files into cards, while Quizlet leans toward finding a set someone already made. If your material lives in lecture slides, the first approach saves time. If your teacher already shared a set, the second does.
Is Knowt actually free?
Yes, with a boundary you should know before you build a semester on it.
Knowt's plans page shows Basic at no cost, described as unlimited file creation, live collaboration and storage, plus browsing millions of resources. The same page marks the things Basic does not include: the AI features, the ad-free experience and the exam prep access. Ultra adds those, at two prices as of October 2026:
| Knowt plan | Price | Billing |
|---|---|---|
| Basic | $0 | None |
| Ultra, annual | $149.99 | Billed up front for the year |
| Ultra, monthly | $24.99 | Charged monthly |
I am quoting the billed amounts because Knowt's own page shows a per-month figure for the annual plan that is easy to misread as the price you pay today. The annual plan is a single $149.99 charge. Third-party roundups of this exact question quote Knowt's paid plan at figures anywhere from about $10 to $25 a month, which is a good reason to open the plans page yourself before paying anyone.
What I could not confirm from the plans page is whether the free plan requires an account. The page shows signup options but does not say. In an earlier check, public Knowt sets were readable without signing in, while creating and saving your own material is tied to an account, since saved sets live in your library. So "free" and "no signup" are different promises here, and Knowt only makes the first.
Free on Knowt also comes with ads. The paid plans list an ad-free experience, which tells you the free plan has them.
What does each one lock behind a paid plan?
Here is the comparison laid out side by side, with QuestionCard included because it is ours and you should see it held to the same standard. Quizlet blocks automated reads of its pricing and help pages, so the Quizlet column reflects the figures from my September check and Quizlet's own published structure, not a fresh read this month. Re-check the upgrade page before you buy anything.
| Knowt | Quizlet | QuestionCard (ours) | |
|---|---|---|---|
| Account required to study | Public sets can be read signed out. Saving your own needs an account | Account needed to save and use study modes beyond public viewing | No account, ever, for any free deck |
| Free study modes | Flashcards, Learn mode and practice tests advertised as unlimited | Flashcards and Match stay free. Learn and Test are limited on free | Every free deck plays in full, card by card |
| Import options | Quizlet import described on its homepage | Exports its own sets | Our own JSON export only. No Quizlet, CSV or Anki import |
| Where the paywall sits | AI tools and exam prep | Adaptive study modes and monthly usage caps | Three premium decks (5 cards free, then an upgrade panel), builder past 1 deck and 20 cards |
| Cheapest paid tier | Ultra monthly $24.99, or $149.99 for the year (as of October 2026) | A paid Plus plan (check Quizlet's own pricing page for the current figure) | Plus $3 a month, billed $18 every 6 months, or $59 once |
Read that table for the shape, not the exact cells. Knowt's paywall protects its AI features. Quizlet's paywall protects its study modes and caps how often you use the premium ones. QuestionCard's paywall is three decks and builder size, and nothing else. None of these is wrong. They just charge for different things, and the right pick depends on which thing you were going to use.
One honest cost note on our side: QuestionCard has no AI generation, no sync between devices and no teacher dashboard. Builder decks live in your browser only. If you need any of those, a tool with accounts is the correct choice.
Can you bring your Quizlet sets across to Knowt?
Knowt says yes. Its homepage says it is easy to bring your existing Quizlets over and study them free, and Knowt is the tool most often named for this move. How the import works has varied across the write-ups I read: some describe pasting a link to a public set, others describe an export-and-paste route, and one mentions a browser extension. That spread usually means the interface has changed over time, so follow the import screen inside Knowt instead of a tutorial.
Whatever route you take, four habits save you from losing work:
- Import ten cards first. Open them and check the formatting, accents, images and any sets with audio before you move a whole library.
- Expect your history to stay behind. Review schedules and progress rarely transfer between tools. Your cards move, your record of what you know does not.
- Check set titles afterward. Some import routes bring in the cards but not the set's name, so a batch of ten sets can land as ten untitled ones.
- Keep an export of your own. Before you leave a tool, find its export button. A destination without one is a landlord, not a tool.
To be exact about our own scope: QuestionCard's builder imports only the JSON file its own export produces. It cannot read a Quizlet export, so it is a place to build fresh decks, not a destination for a bulk move. Our guide to free Quizlet alternatives maps which tools take imports and which do not.
Which one suits a class set versus solo revision?
A class set a teacher hands out. This is where accounts earn their place, because sharing, rosters and progress all need an identity. Quizlet has the larger habit among teachers, so the set your class uses is often already there. Knowt covers the sharing case on its free plan with live collaboration, which is genuinely useful for a study group building a set together.
Solo revision from your own notes. Knowt has the advantage if your source is slides, a PDF or a recording, because that is where its AI tools sit, with the caveat that the heavier ones are on the paid plan. Quizlet works well if someone has already made the set you need.
A fixed exam date with limited time. The scheduler matters less than how fast you can get material into cards and how many passes you can make. The mechanic that makes any of these tools work is retrieval: recalling an answer before you look at it. Carnegie Mellon's Eberly Center summarizes why that beats rereading, and a card that asks, waits and then shows the answer is doing it no matter whose logo is on it. Spacing your passes helps too. A review of the spacing effect and long-term retention in Cureus reports that spaced study outperforms massed study for durable memory. If you want to plan the passes yourself, our spaced repetition schedule post builds one backwards from your test date.
Ten minutes before a quiz. Setup cost dominates. Anything that asks you to create an account before the first card flips is slower than the useful part of the session.
When do you not need an account at all?
More often than the comparison pages suggest. If the deck already exists and you only want to drill it, you do not need a library, a login or a plan. You need a card, a flip and an answer.
That is the case QuestionCard is built for. Open a deck from the flashcard hub and the cards flip with no signup and no email. Missed cards re-queue so you keep seeing the ones you got wrong. US state capitals, the periodic table and multiplication facts are all free and play start to finish with nothing held back.
If you do want your own cards, the builder is free for 1 deck of up to 20 cards, stored in your browser. That is enough for a single quiz or a short vocabulary list, and it is small on purpose. Past that, a tool with accounts and sync is the better fit. I would rather say that than pretend a 20-card cap suits a semester of biology.
A practical way to decide: try the no-account route for the next study session. If you end up wanting sync, shared sets or AI-made cards from your slides, you will know exactly which of those you missed, and that tells you which paid plan, if any, is worth the money. A study habit that never needs the plan is the cheapest outcome on the table.
Short bursts also beat long sessions for most people. UNC's Learning Center recommends spreading flashcard review through the day rather than one marathon, and that habit change costs nothing in any of these apps.
Frequently asked questions
Is Knowt better than Quizlet?
It depends on what you need. Knowt is better if you want unlimited study modes on a free plan and plan to turn your own notes or slides into cards. Quizlet is better if the set your class uses already lives there. Knowt's own homepage says its free plan has unlimited Learn mode and unlimited practice tests, while Quizlet limits how often you can use its premium modes on free. Compare them on the one feature you will actually use, not on the full feature list.
Is Knowt completely free?
No. As of October 2026, Knowt's Basic plan costs nothing and includes unlimited file creation, live collaboration and storage, plus browsing millions of resources. AI summarizers, the podcast generator, the voice tutor, the ad-free experience and AP, SAT and ACT prep are on Ultra, which is $149.99 billed up front for the year or $24.99 month to month. Check the plans page before paying, since third-party roundups quote it inconsistently.
Can you import Quizlet into Knowt?
Knowt says so on its homepage, and it is the most commonly recommended destination for a Quizlet move. The exact steps have been described several ways (pasting a public set's link, pasting an export, or an extension), so follow the import screen in the app. Import ten cards first, check formatting and set titles, and expect your review history to stay behind. QuestionCard's builder does not import from Quizlet. It reads only its own JSON export.
Does Knowt have a learn mode like Quizlet?
Yes. Knowt's homepage advertises a free Learn mode with unlimited rounds and customizable question types, including multiple choice, true or false and fill in the blank. Quizlet's Learn mode is the one that moved toward being a subscriber feature, with a limited amount on free accounts. For a practice-first student, that single difference is the reason many people search for the comparison at all.
Want to see what a free study session feels like before deciding? Open a flash card deck with no account and no email, or build one of your own for free, 1 deck of up to 20 cards. If you outgrow it, Plus is $18 every 6 months or $59 once, and the price is on the page.
