Machi.study or Quizlet?

We made Machi.study, so treat this the way you would treat anyone comparing themselves to someone else. What we have tried to do is only say things you can check.

The short answer

Nothing on Machi.study is behind a payment. Every mode, no limits: all five ways to study — flashcards, review, learn, match and a full practice test — are open to everyone. There’s no tier, no round limit and no upgrade screen.

That’s the difference you can check in about a minute, so it goes first.

The second one takes longer to see: Machi.study puts every card on its own schedule and shows it to you when you’re about to forget it. Not the set — each card. Most apps don’t show you their scheduling at all, so you can’t tell what your answer did or when the card comes back.

Where your money goes

Quizlet has a paid tier, and some study features are limited unless you’re on it. Check their current terms yourself — they change, and we’re not going to quote numbers at you that might be out of date by the time you read this.

Machi.study has no paid tier. It’s paid for with advertising, and that’s a genuine trade: you see ads and they don’t. We think that’s the right trade for a school app, because the students who most need a study tool are often the ones least able to expense one. But it is a trade, and you should decide it knowing that.

What we’ve put in writing about those ads: they don’t move, don’t make a sound, don’t cover your work, and there’s nothing you have to close before you can answer. Nothing on a screen with a question on it. If we break that, hold us to it.

What Machi.study does that’s different

• Every card has its own schedule. The three terms you keep mixing up come back tomorrow. The twelve you already know sit quiet for a month. You never decide what to study — the app already knows.
• The scheduler is FSRS, and we will name it. It’s a published memory model that estimates how likely you are to remember each card today, and it is the same algorithm Anki switched to. It isn’t ours and we didn’t invent it. Most study apps either hide what they use or built something in-house and call it spaced repetition; you can read ours in the code.
• You can see the schedule. When you answer in Review, the buttons say what each one costs you: ten minutes, or a minute. Most apps hide their scheduling entirely, so you can’t tell what your answer did.
• Two buttons, not four. Got it, or Not yet. “Was that hard or very hard” is a question nobody answers honestly at eleven at night, and a wrong answer to it makes your schedule worse.
• Nothing is ever taken away. No streak to break, no score to lose. Press Not yet as often as you need to — it costs you nothing and it’s the only way the schedule can help.
• Share a set and it just opens. Whoever you send it to can study it with no account and nothing to fill in.
• Your own colors. Build a theme and Machi.study checks the contrast is actually readable before it lets you keep it.

What Quizlet does better

Being straight with you, because you’ll find this out anyway:

• There are millions of sets already made. If your exact textbook chapter is on there, that’s hours you don’t spend typing. Machi.study is new and small, and mostly you’ll be making your own.
• It has been around for years. It’s on every phone, everyone knows how it works, and your class group chat is probably already full of its links.
• Proper mobile apps. Machi.study runs in a browser. It works well on a phone, but it’s not in an app store.
• It won’t disappear. We intend to be here for a long time, but we’re new, and that’s a fair thing to weigh.

If what you need is a set for tonight that somebody else already typed up, that is a real reason to use the bigger library. We’d rather say so than pretend.

So which one

Use Machi.study if you’re studying something over weeks — a unit test, finals, a language — and you want to actually still know it afterwards. That is what the scheduling is for, and it’s where the difference is largest.

Use Machi.study if you’re paying for a study app and would rather not.

Stick with what you have if you need a ready-made set on a topic tonight and don’t want to type one.

You don’t have to pick, either. Plenty of people make the set where it’s easiest and study it where it works best.

Machi.study isn’t the only other option

Quizlet is the one everybody knows, but it isn’t the only alternative and pretending otherwise would be the kind of thing this page is trying not to do.

Anki is free, open source, and has been the serious answer for twenty years. Medical students live in it. It uses the same FSRS scheduler Machi.study does, and its deck library is enormous. Two honest catches: the iPhone app is a paid one-off, and it is genuinely hard to learn — it is a power tool with settings pages, not something you open the night before a test. If you like tinkering and you study every day for years, Anki is probably better than us and we would rather say so.

Knowt is free, built for American high schoolers, and does AI notes. If what you want is something to turn a lecture recording into cards, it does that and we don’t.

What none of them is: free, scheduled by a published memory model, and built for somebody in high school who has a test on Friday. That gap is the whole reason Machi.study exists.

Bringing your sets over

Copy the terms from wherever they are and paste them into the box. It doesn’t matter which app they came from, and a rough copy is fine — Machi.study reads the gap between the two columns.

Your own sets only. Somebody else’s cards are theirs, and that’s true wherever you found them. Our terms say the same thing and we mean it.

One thing we can’t prove to you here

Spaced repetition feels like it isn’t working while you’re doing it. The gaps feel too long, the sessions feel too short, and there’s no satisfying pile of highlighted notes at the end. Then the test comes and you know it.

That’s the whole method and it’s also the hardest thing to sell. Why cramming feels like it works explains why you can’t judge this from the inside.

How Machi.study works is the longer version of all of this. Or just make an account and bring one set over — it takes about a minute and you’ll know within a week.

When we checked

Everything above about Machi.study is true as we ship it. Everything about any other app is general and deliberately has no numbers in it, because those change and we’d rather be right than specific.
