Overview
Anki's algorithm is the gold standard, but making cards is miserable. Here are 7 Anki alternatives ranked by who they're for, from free AI card generators to the original SuperMemo.
Anki is the gold standard of spaced repetition. The FSRS algorithm is genuinely excellent, it's free on desktop, and power users swear by it for good reason. But there's a reason "Anki alternatives" gets searched so much: the interface is from another era, the learning curve is a cliff, and — the real killer — making the cards is miserable. You spend more time formatting cards than reviewing them, and the deck you never finished building is the deck you never studied.
If you love the science of spaced repetition but hate the card-making chore, this list is for you. Seven alternatives, honest about who each one is for. Pricing changes constantly, so every number here is approximate — check current pricing before you commit.
First, what are you actually trying to escape?
People leave Anki for one of three reasons. Knowing yours makes this list shorter:
- The card-making grind. You want cards generated from your notes/PDFs automatically. (Most of this list.)
- The interface. You want the FSRS algorithm but a modern, friendly UI.
- The mobile cost. AnkiMobile is a one-time ~$24.99 on iOS (verify current pricing) and you'd rather not.
If you only hate the UI but love everything else, honestly, just install a nicer Anki theme and learn the keyboard shortcuts — nothing matches Anki's algorithm maturity. For everyone else, read on. And if spaced repetition itself is new to you, start with our primer on how spaced repetition works so you know what you're protecting.
1. QuerySpark — for people who hate making cards
Disclosure: QuerySpark is our tool. We built it specifically for the "I love spaced repetition but won't sit there typing cards" problem. Upload a PDF, lecture notes, or a video and it generates flashcards and exam-style questions automatically, with spaced repetition built in. The pitch isn't "better algorithm than Anki" — it's "you'll actually have a deck because you didn't have to build it by hand."
- Best for: students with lots of source material and no time to hand-make cards.
- Watch out: auto-generated cards still deserve a quick review for quality. And if you're a tweak-every-interval power user, Anki gives more manual control.
- Try it: AI flashcard generator or generate a full quiz with PDF to questions.
2. Knowt — generous free tier, AI from video
Knowt is the popular free flashcard app that auto-generates cards from notes, PDFs, and videos. Its free tier is unusually generous, which makes it a natural Anki escape hatch for people who mostly hate the cost-and-friction combo.
- Best for: students who want free AI card generation with a modern UI.
- Watch out: the scheduling isn't as battle-tested as Anki's FSRS for hardcore long-term retention.
3. Quizlet — the familiar default
Quizlet won't replace Anki for serious spaced repetition, but its Learn mode does light scheduling and its enormous library means you often don't have to make cards at all. Quizlet Plus runs roughly ~$7.99/month (verify) and the free tier has ads.
- Best for: common courses and standardized tests where a great set already exists.
- Watch out: not a true SRS — fine for vocab, weak for long-term retention of large decks. See our full QuerySpark vs Quizlet breakdown.
4. RemNote — notes and SRS in one
RemNote merges note-taking with spaced repetition: you write notes and turn phrases into flashcards inline, so cards are a byproduct of studying rather than a separate chore. It's a favorite among med students.
- Best for: people who want their notes and cards to live in the same app.
- Watch out: the all-in-one model has its own learning curve, and deeper features sit behind a paid tier (verify pricing).
5. Memrise — for language learners
Memrise leans hard into languages, with spaced repetition plus native-speaker video clips and a gamified feel. If your "deck" is vocabulary in another language, it's more engaging than raw Anki.
- Best for: language vocabulary and phrases.
- Watch out: not built for general academic content; less flexible than Anki for custom material.
6. Brainscape — confidence-based repetition
Brainscape uses a confidence-rating system (you rate 1-5 how well you knew each card) to drive scheduling. The UI is clean and there's a large library of pre-made decks.
- Best for: people who want a polished, simple SRS without Anki's complexity.
- Watch out: the algorithm is simpler than FSRS; much of the good stuff is behind a subscription (verify).
7. SuperMemo — the original (for purists)
SuperMemo invented the spaced-repetition algorithms everything else descends from, including the incremental-reading workflow that turns articles into cards as you read. It is powerful and famously idiosyncratic.
- Best for: algorithm purists and incremental-reading devotees.
- Watch out: the interface and learning curve make Anki look friendly. Not for the faint of heart.
Quick comparison
| Tool | Auto-makes cards? | SRS strength | Best for |
|---|---|---|---|
| QuerySpark | Yes (notes/PDF/video) | Built-in | Hating the card grind |
| Knowt | Yes, free | Good | Free AI cards |
| Quizlet | Partial | Light | Pre-made sets |
| RemNote | Inline from notes | Strong | Notes + cards together |
| Memrise | For languages | Good | Language vocab |
| Brainscape | No | Medium | Simple, polished SRS |
| SuperMemo | Incremental reading | Strongest/oldest | Algorithm purists |
How to choose without overthinking it
- Hate making cards above all? Pick a generator — QuerySpark or Knowt — so a deck actually exists. An empty Anki is worse than an auto-made deck you'll review.
- Love Anki's algorithm but not its UI? Honestly, stay on Anki and learn the shortcuts. Nothing fully matches FSRS maturity.
- Studying languages? Memrise.
- Want notes and cards unified? RemNote.
Whatever you choose, the algorithm only helps if you show up daily. Pair it with active recall — always try to answer before flipping the card — and let proper spaced repetition software handle the scheduling so you stop guessing when to review.
Frequently asked questions
Is anything actually better than Anki's algorithm?
Honestly, no — Anki's FSRS is the most mature, best-tested spaced-repetition scheduler available, and SuperMemo's algorithms are its only real intellectual rival. The alternatives on this list win on convenience (auto-made cards, nicer UI, free tiers), not on raw scheduling science. If algorithm quality is your only criterion, stay on Anki.
Are there truly free Anki alternatives?
Yes. Anki itself is free on desktop and Android (AnkiMobile on iOS is a one-time ~$24.99 — verify current pricing). Among alternatives, Knowt's free tier is the most generous for AI-generated cards. Most others have a usable free tier with paid upgrades; check current pricing on each, as it changes often.
Which alternative is best if I just hate making cards?
A generator that builds cards from your source material — upload a PDF or notes and get a deck back. That removes the single biggest reason people abandon spaced repetition: the deck they never finished building.
Can I import my Anki decks into these tools?
It varies by tool and is worth checking before you switch, since rebuilding a large deck from scratch is painful. Some apps support Anki imports; others expect you to generate fresh cards from your materials. If you have a deck you love, confirm import support first.
The bottom line
Anki is still the most powerful spaced-repetition engine on the planet, and if you can stomach the card-making, you won't beat it. But the best SRS is the one you actually use, and a half-built Anki deck teaches you nothing. If the card grind is what's stopping you, switch to something that builds the deck for you. Try generating a flashcard set from your own notes with the AI flashcard generator and see how much faster you get to the part that matters — reviewing. Curious how these stack up beyond just cards?
