Anki and Quizlet are the 2 names every student hears first. They're both flashcard apps, and that's roughly where the similarity ends. One is free, powerful and looks like it was designed in 2006 (it was). The other is polished, social, and charges you for the modes that actually help.
Here's an honest comparison, plus what to do if neither fits.
The short version
| Anki | Quizlet | |
|---|---|---|
| Price | Free on desktop and Android; $24.99 once on iOS | Free tier with ads and limits; Quizlet Plus is a subscription |
| Spaced repetition | Yes, the whole app is built on it | No true long-term scheduling |
| Ease of use | Steep learning curve | Easy, you'll have a set in minutes |
| Pre-made decks | Huge shared library, quality varies | Millions of user sets, quality varies |
| Card creation | Manual (plus add-ons) | Manual, plus AI generation on paid plans |
| Best for | Med, law, languages, anything with thousands of facts over months | High school, quick cramming, group study |
What Anki does well
Spaced repetition that works. Anki schedules each card based on how well you knew it last time. Easy cards drift out to weeks and months. Hard cards come back tomorrow. This is the feature that matters, and Anki's implementation (including the newer FSRS algorithm) is the best in the category.

The evidence is decent. A 2023 cohort study of medical students (Lu et al., published in Cureus) found Anki users scored around 6 to 13 percent higher across preclinical exams and a national standardised exam than non-users. Correlation, not proof, but consistent with decades of spacing research.
It's free. Desktop and Android cost nothing. The iOS app is a one-off $24.99 that funds the whole project. No subscription, no locked modes.
It's customisable to a fault. Cloze deletions, image occlusion, custom card templates, hundreds of add-ons. If you want it, someone has built it.
Where Anki hurts
Making cards is the whole job. Anki gives you an empty deck and a text box. For a 60-page lecture set, that's an evening of typing before you've reviewed anything. Most people who quit Anki quit here.
The learning curve is real. Deck options, ease factors, interval modifiers, learning steps. The defaults are fine, but the settings screen looks like a cockpit and it scares people off.
It looks dated. This is cosmetic, but it affects whether you open the app every day, and daily use is the whole point.
What Quizlet does well
Speed. You can build a set, share it with your class, and start studying in 5 minutes. Nothing to configure.
Modes. Learn, Test, Match, and (on paid plans) AI-generated practice tests and study guides. Variety keeps you going when plain flip-cards get boring.
Pre-made content. If you're studying a standard course, someone has probably already made the set. Quality varies a lot, so check before you trust.
Where Quizlet hurts
No real spaced repetition. Learn mode repeats what you got wrong in the same session. It doesn't model forgetting over weeks. If your exam is in 6 weeks, Quizlet will let you feel confident on day 1 and forget by day 30.
The good modes cost money. The free tier has ads and caps on Learn and Test. Quizlet Plus is a recurring subscription, and the AI features live behind it.
You still type every card. AI generation exists on paid plans, but the free experience is the same manual entry as Anki with a nicer font.
So which one?
Pick Anki if you have thousands of facts to retain for months, you're willing to spend a weekend learning it, and you're going to review daily. Medical students, law students, language learners.

Pick Quizlet if you need something quick and social for a test next week, you like variety in study modes, and long-term retention is a lower priority than getting through this unit.
Pick neither if the thing stopping you is making the cards. That's the shared weakness, and it's the one most students actually hit.
A third option: generate the deck, then review it with spaced repetition
The card-creation problem is why AI flashcard tools exist. Upload the lecture slides or the PDF, get a deck back, edit the cards that are wrong, and start reviewing. The typing evening disappears.
StudyFox does this and keeps the part of Anki that matters: spaced repetition runs on every deck, including the free plan. It also imports Anki .apkg files directly, so if you've already built decks in Anki (or downloaded shared ones) you don't lose them. Deck hierarchies and cloze cards come across as-is.
The same upload also produces quizzes, mind maps and notes, which is handy when flip-cards alone stop working for a topic.
If you're deciding whether to move, we've written separate guides on switching from Anki and switching from Quizlet, including how to export your existing sets.
What we'd actually recommend
Honestly? Anki's scheduling is excellent and it's free. If you can push through the setup and you enjoy tinkering, use it.
If you've tried Anki and bounced off, or you're paying for Quizlet Plus mainly for the AI generation, a tool that generates cards from your material and schedules them properly gets you most of Anki's benefit with none of the evening spent typing.
Whichever you choose, the app matters less than the habit. 15 minutes of review every day beats the perfect app used twice a month.
