Anki
Verified working Aug 3, 2026
Spaced-repetition flashcards for everything from facts to huge decks.
Anki is an open-source flashcard app built around spaced repetition, scheduling reviews based on how well you remember each card. It supports rich card content, syncing through AnkiWeb, custom review settings, shared decks, and add-ons for extending the app beyond basic flashcards.
Why it stands out
- Handles very large collections, including decks with 100,000+ cards.
- Open-source desktop app with a long-running community around add-ons, translations, and shared decks.
- Free AnkiWeb sync lets the same collection move across devices without a separate paid subscription.
- Card layout and scheduling behavior can be deeply customized for advanced study systems.
- Supports richer learning material than plain text flashcards, including media and scientific markup.
Good to know
- The official iOS app, AnkiMobile, is paid, while the desktop app and AnkiDroid are free.
- Advanced templates, review settings, and add-ons can introduce a learning curve for new users.
- Current desktop downloads require relatively recent operating systems, such as Windows 10+ or macOS 13+.
Under the radar: Before making a deck from scratch, check Anki’s Shared Decks section and treat a good existing deck as raw material—editing cards to match your own wording usually makes reviews more effective.

Students, language learners, and exam candidates use Anki to retain large volumes of material over months or years. Build a deck for vocabulary, formulas, anatomy, legal rules, or other recall-heavy subjects. Sync cards between desktop and mobile so daily reviews can happen anywhere. Download a shared deck as a starting point, then adapt it to your course or workflow. Use media-rich cards for pronunciation, diagrams, screenshots, or scientific notation.
