Bellek vs Anki: Which Vocabulary Tool Is Right for You?

The Short Answer

Anki is the gold standard for spaced repetition flashcards. It's incredibly powerful, infinitely customizable, and free. If you already have vocabulary lists and want maximum control over your review schedule, Anki is hard to beat.

Bellek is built for people who want to learn vocabulary from what they actually read — without the manual work of creating flashcards. It captures words with context while you browse, translates into 20 languages, and includes spaced repetition, quizzes, and smart review built in.

The best approach for many learners? Use both. Bellek for discovering and saving new words effortlessly while reading. Anki for deep, long-term drilling of your most important vocabulary. They complement each other perfectly — and Bellek supports CSV import and export so moving words between them is easy.

Use Both Together — The Best of Both Worlds

Many serious learners use Bellek and Anki as a combined workflow. Here's how:

1

Discover with Bellek. Browse the web normally. When you encounter a new word, highlight it, see the definition and translation, and save it with one click. Context and source are captured automatically.

2

Export to Anki. Once you've collected words, export your Bellek collection as a CSV file. The export includes the word, definition, context sentence, translation, and difficulty level.

3

Drill in Anki. Import the CSV into Anki and use its powerful spaced repetition system for long-term retention. Customize card templates, set review schedules, and add audio or images.

This way, Bellek handles the discovery and context capture (the hardest part), and Anki handles the deep drilling (what it does best). You can also import Anki decks back into Bellek via CSV if you want to review on the go via mobile sync.

Where Anki Wins

We're honest about this. Anki is better than Bellek at several things:

Algorithm depth. Anki's spaced repetition system (especially with the FSRS scheduler) is more sophisticated and configurable than Bellek's.
Customization. Card templates, deck options, scheduling parameters, add-ons — Anki lets you control everything.
Ecosystem. Thousands of shared decks, community add-ons, and 15+ years of community knowledge.
Scope. Anki handles any subject — medicine, law, music theory, languages. Bellek is focused on vocabulary.
Native mobile apps. Anki has full-featured iOS and Android apps. Bellek uses a mobile-optimized web app via QR code sync.
Mature and battle-tested. Anki has been around since 2006. It's not pretty, but it's rock-solid and trusted by millions of medical students, language learners, and power users worldwide.

Where Bellek Wins

And here's where Bellek has the edge:

Modern, clean interface. Bellek is designed to feel intuitive from the first click — a polished popup, a visual dashboard with streaks and mastery tracking, and study modes that just work. Anki's interface is functional but dated, and customizing it requires editing HTML/CSS card templates.
Zero-friction word capture. Highlight → definition → save. Under 2 seconds. No manual card creation.
Context is automatic. Every word is saved with the sentence where you found it, the source URL, and difficulty level.
Built-in definitions and translations. No need to look up words separately — definitions with synonyms and examples appear instantly, plus translations in 20 languages.
Works on mixed-language pages. Reading an English article with Japanese or Arabic words? Bellek handles it automatically.
Instant setup. Install the Chrome extension and start learning in 30 seconds. No deck configuration, no add-on hunting.
Multiple study modes built in. Flashcards with spaced repetition (free), Multiple Choice Quiz, and Smart Review — no add-ons needed.
