Quizlet used to be the default answer for flashcards. Then Learn mode went behind a paywall, practice tests followed, and the free tier filled up with ads. If you've landed here, you're probably looking for Quizlet alternatives that still let you study without pulling out a credit card mid-semester.
Good news: you have options, and most of them are free. This list covers six study apps worth switching to, what each one does well, and where each one falls short. No tool is perfect, so every entry includes the honest downsides too.
Why look for a Quizlet alternative?
Quizlet is still a decent app. The problem is what happened to its free tier.
In 2022, Quizlet moved Learn mode and practice tests into Quizlet Plus, a paid subscription. Learn mode was the feature most students actually relied on: it adapts to what you keep getting wrong and drills you until the material sticks. Losing it turned the free version into little more than a deck viewer with ads.
So when comparing apps like Quizlet, it helps to check three things:
- What's actually free. Some apps advertise a free plan that locks the useful study modes, which is the exact problem you're trying to escape.
- How cards get made. Typing hundreds of cards by hand is the slowest part of flashcard studying. Newer tools generate cards from your notes or readings for you.
- Whether it uses spaced repetition. Spaced repetition schedules reviews right before you'd forget, which is far more efficient than cramming a full deck every night.
With that in mind, here are the best Quizlet alternatives right now.
1. Heuristica: best for turning your own material into study tools
Heuristica takes a different approach from Quizlet. Instead of typing cards one by one, you upload the material you're studying, like a PDF, a lecture video, or an article, and the AI generates flashcards from it directly.
That difference matters more than it sounds. The slowest part of flashcard studying has never been the reviewing, it's the card-making. If your professor posts a 40-page reading every week, hand-typing decks stops being realistic. Generating them from the source and then editing the weak cards is a much better use of your time.
The deck is also just the starting point. Heuristica can convert your flashcards into study notes, quizzes, concept maps that show how the ideas connect, and mind maps. And when a card alone doesn't explain enough, you can chat with your flashcards to get examples or a clearer explanation, something no traditional flashcard app offers. Everything stays linked to the original source, so you can always trace a card back to where it came from.
Where it falls short: if you want to browse millions of premade decks the way you can on Quizlet, Heuristica isn't built for that. It works from your material, not a public library. The free plan is enough to study with, and heavier use needs a subscription.
Best for: students who want strong flashcards plus notes, quizzes, and concept maps in one tool, with the busywork done for them.
2. Knowt: best like-for-like Quizlet replacement
If all you want is Quizlet the way it used to be, Knowt is the closest match. It looks and feels like Quizlet, its learn mode is free, and it can import your existing Quizlet sets in a couple of clicks, so you don't lose the decks you've already built.
Knowt also added AI note and flashcard generation, plus a large library of user-made decks to browse. For a straight swap with the least friction, it's the obvious pick.
Where it falls short: the free tier is ad-supported, and the AI features have monthly limits until you pay. Some users also find the interface busier than Quizlet's.
Best for: students who want free learn mode back and don't want to change how they study.
3. Anki: best free spaced repetition, if you can handle it
Anki is the tool serious memorizers end up with. It's completely free on desktop and Android, open source, and its spaced repetition algorithm is the reason medical students swear by it. Decks made by past students for specific courses and exams, like the med school AnKing deck, are a genuine superpower.
The catch is the experience. Anki looks like software from 2008, card formatting is fiddly, and the settings menu is famously confusing for beginners. There's a real learning curve before it clicks. Also worth knowing: the desktop and Android apps are free, but the official iPhone app costs $24.99 as a one-time purchase.
Where it falls short: dated interface, steep setup, no built-in AI generation, and you make every card yourself unless you find a shared deck. For a deeper look at how it stacks up against Quizlet, see our full Anki vs Quizlet comparison.
Best for: long-haul memorization like med school, law, or language vocabulary, where the time invested in learning the tool pays off over years.
4. Brainscape: best for confidence-based review
Brainscape replaces Quizlet's game modes with one core mechanic: after each card, you rate how well you knew the answer from 1 to 5, and that rating decides when you'll see the card again. This confidence-based repetition is simple and surprisingly effective, and the clean interface stays out of your way.
It also has a certified deck library covering standardized tests and professional certifications, which is useful if you'd rather study a vetted deck than a random user's.
Where it falls short: the free plan is limited, and most of the premade library sits behind a subscription. Card creation is manual and the card format is fairly rigid (no images on the free tier).
Best for: self-paced review where you want a dead-simple system and don't mind paying for premade content.
5. Memrise: best for language learners
Memrise used to be a general flashcard app, but it has fully committed to language learning. That focus is exactly why it earns a spot here: if the reason you used Quizlet was vocabulary drilling, Memrise does that job better. Courses include audio and video clips of native speakers, so you learn how words actually sound in conversation, not just how they're spelled.
Where it falls short: it's no longer a general study tool. You can't use it for biology definitions or history dates, and the classic user-created courses have been phased out. The free tier is limited to a portion of each course.
Best for: vocabulary and phrase practice in a new language.
6. RemNote: best for flashcards inside your notes
RemNote merges note-taking and flashcards into one app. As you write your lecture notes, you mark certain lines as flashcards, and RemNote schedules them with spaced repetition automatically. Your notes and your review queue are the same document, which removes the step of turning notes into decks later.
It also supports PDF annotation and image occlusion (hiding labels on a diagram to quiz yourself), which makes it popular with med students who don't want to run Anki alongside a separate notes app.
Where it falls short: it's a lot of app. If you just want flashcards, the outliner-style note system gets in the way, and the learning curve is closer to Anki than to Quizlet. The free plan covers the basics; PDF features need a paid plan.
Best for: students who take detailed digital notes and want reviews generated from them in the same place.

What is a free alternative to Quizlet?
The short answer: Knowt is the best free like-for-like replacement, with a free learn mode and Quizlet set import. Anki is the best fully free option on desktop if you're willing to learn it. Heuristica is the best free option if you'd rather have AI build the study material from your readings instead of making cards yourself.
And yes, you can usually bring your decks with you. Knowt imports Quizlet sets directly, and Anki can import them via exported text files, so switching doesn't mean starting over.
Which one should you pick?
It comes down to how you study. If you miss old Quizlet, get Knowt. If you're memorizing thousands of facts over several years, invest the setup time in Anki. If you're learning a language, Memrise. If your notes are your study system, RemNote.
And if your studying starts from course material, the PDFs and lectures piling up every week, try Heuristica for free. Upload something you need to learn this week and see what it builds: flashcards, a concept map, and a quiz, before you'd have finished typing your first deck by hand.
