Anki Alternatives — What to Use When You Want SRS Without the Setup
Anki's spaced-repetition algorithm is the gold standard. Its 2010-era desktop UI and manual card-writing are not. Here's what actually replaces it.
Anki has been the standard for spaced-repetition flashcards since Damien Elmes released the first version in 2006. Its algorithm (SM-2, and now the newer FSRS) is genuinely state-of-the-art, its ecosystem includes irreplaceable community decks like AnKing (medical), Refold (languages), and Fluent Forever, and it's free on desktop. If you want the most powerful SRS on the planet and don't mind investing hours in setup, Anki is still the answer.
But the same qualities that make Anki loved by power users make it painful for everyone else. The desktop UI dates to Qt 5 and looks it. AnkiMobile costs $25 one-time on iOS while Android is free — a UX inconsistency that trips up every switching student. Card creation is fully manual: you write every prompt yourself, and image occlusion requires an add-on. Sync between clients works but has been known to fail in ways that produce card duplication.
This page compares the alternatives students actually pick when Anki friction outweighs its power. It covers Ellie, RemNote, Brainscape, and Quizlet's newer Learn mode, with honest notes on what each replaces and what it doesn't.
What people are actually escaping when they leave Anki
Nobody switches away from Anki because the algorithm stops working. The complaints are consistent across Reddit's r/Anki, the medical school subreddits, and language-learning forums:
- Time cost of writing every card by hand — 60–90 minutes per lecture is typical
- Add-on hell — image occlusion, hierarchical tags, and morphman require third-party plugins that break on Anki version bumps
- Sync inconsistencies between AnkiWeb, AnkiMobile, AnkiDroid, and desktop
- $25 iOS app that new students find surprising (Android free, desktop free)
- UI that looks and behaves like a scientific tool, not a study app
- Community deck bloat — AnKing v12 ships with 30k+ cards, most of which you'll never see
Ellie — the AI-generation alternative
Ellie is built around one insight: card writing is the bottleneck, not review. You paste a PDF, notes, or a lecture transcript; Ellie generates atomic Q/A cards, cloze deletions, and MCQs; you edit and start reviewing the same day. Spaced repetition is built in on an SM-2 derivative that produces the same long-term retention curve as Anki for typical study patterns.
What Ellie does not replace: the community-vetted mega-decks (AnKing, Refold). If you want a curated 30k-card deck someone else built and maintained for a decade, keep Anki for that piece. What Ellie does replace: writing your own cards from lectures, textbook chapters, and question banks — which is 80% of what most students actually do in Anki.
RemNote — the note-taking hybrid
RemNote lets you write outline-style notes and mark any bullet as a flashcard inline. Reviews run on an SM-2-derived algorithm. It's the closest thing to 'Notion with SRS' and has a strong following among medical and law students who want their study material and their cards in the same document.
Tradeoffs: the free tier is generous but the paid tier is required for offline mobile and image occlusion. The learning curve for hierarchical note structure is steep — if you don't organize notes carefully, review sessions become chaotic.
Brainscape — the confidence-rating alternative
Brainscape's twist is confidence-based repetition: after every card, you rate your confidence 1–5, and the algorithm schedules the next review based on your rating. This creates more retrieval effort per card than Anki's Again/Hard/Good/Easy split. Their curated deck library is small but professionally reviewed (unlike Quizlet's user-generated pile).
Downsides: no meaningful AI generation, weaker mobile app than Ellie or Quizlet, and the confidence-rating model feels slow if you're reviewing 200+ cards a day.
Quizlet — only if you want breadth over depth
Quizlet is the largest flashcard platform on the internet, with hundreds of millions of user-created decks. If you're memorizing common high school or intro-college content, someone has already built the deck. Quizlet Learn mode adds a basic adaptive review system, and Quizlet Plus adds AI-generated content.
The catch: Quizlet's algorithm is not real spaced repetition. Long-term retention curves are noticeably worse than Anki, Ellie, RemNote, or Brainscape. If your exam is next week, Quizlet is fine. If your exam is in six months, use something else.
How to actually migrate
Export from Anki as .apkg (File → Export → Include scheduling information: off, if you want a clean start; on, if you want to preserve mature intervals). Ellie accepts .apkg directly. RemNote requires converting to CSV first (via Anki's CSV export). Brainscape has a Quizlet importer but no Anki importer — you'll need CSV.
Real talk: keep your Anki database backed up until you've verified the new tool works for at least two full review cycles. Migration regret is more common than migration success.
Frequently asked questions
Is Anki really free forever?
Desktop Anki is free and open-source (BSD-3 license). AnkiWeb sync is free with a 100 MB media limit. AnkiDroid is free. AnkiMobile on iOS is a one-time $24.99 purchase — the only paid piece — and the revenue funds Damien Elmes's continued development of the desktop version. So 'free forever' with an asterisk if you're on iOS.
What's FSRS and is it better than SM-2?
FSRS (Free Spaced Repetition Scheduler) is a newer algorithm added to Anki in late 2023 that tunes scheduling per-user based on your actual review history. Independent studies suggest 20–30% fewer reviews for the same retention rate compared to SM-2. It's now the default in Anki 24.x. Most modern SRS alternatives (Ellie included) use SM-2 derivatives with similar tuning, so retention curves are broadly comparable.
Can I keep AnKing running while trying Ellie?
Yes — most switchers keep AnKing on Anki for the curated content and use Ellie for their own generated cards. You end up with two review queues but the workload is often lower overall because you stop hand-writing new cards. Import AnKing's tag structure into Ellie if you want a unified organizational system.
What about the language-learning use case?
For language learning, Anki with the Refold or Fluent Forever methodology remains extremely strong because those methodologies were designed around Anki. Ellie is faster for vocabulary generation from a text you're reading; Anki is stronger for structured multi-year immersion decks. Many polyglots use both.
Is there a fully-open-source Anki alternative?
Not really. Mnemosyne is the closest — it's open source and uses an SM-2 variant — but development is slow and the UI is even more dated than Anki's. If open source is a hard requirement, stay with Anki and consider contributing to Anki-Web or FSRS improvements.
Which alternative is cheapest?
Ellie has a free tier that covers most personal use. RemNote has a generous free tier. Brainscape is subscription-only above a small free preview. Quizlet is freemium with heavy paywalling of Learn features. If pure cost minimization is the priority, Anki desktop (free) plus AnkiDroid (free) remains the cheapest path — you just pay the time cost of writing every card.
How does Ellie's retention compare to Anki's?
For typical study patterns (250–400 reviews per day), retention curves are comparable at the 3-month and 6-month marks. Anki's edge appears at very high card counts (10k+ mature cards) where its scheduling precision compounds. Ellie's edge appears at the card-writing stage: you're studying cards you generated in minutes, not hours, so total time-to-mastery is often shorter overall.
