Learning a word once isn't enough. Bellek uses spaced repetition to show you words right before you'd forget them — so vocabulary sticks long-term.
Learning a word once isn't enough. Research consistently shows that reviewing information at increasing intervals — right before you'd forget it — is the most effective way to move knowledge into long-term memory. This is spaced repetition.
The problem? Most people don't have time to manually schedule reviews. That's where Bellek comes in.
Bellek's flashcard system is built on spaced repetition algorithms that work automatically:
Unlike standalone flashcard apps, Bellek combines spaced repetition with a complete vocabulary learning system:
Save words while browsing any website. Every word captured with the sentence where you found it.
Set your preferred language and see translations alongside English definitions. Saved with the word for review.
Add memory cues or custom definitions right in the popup before saving.
Group words by topic, course, or project. Study one collection or all at once.
Multiple choice quizzes test active recall, not just recognition. (Premium)
A focused mode that only shows words you've marked as difficult. (Premium)
Your dashboard shows daily streaks, mastery percentages for each word, weekly goals (choose from light to intensive), session history, and personalized insights. See at a glance which words are mastered and which need more practice.
Already have vocabulary in Anki, Quizlet, or spreadsheets? Import via CSV and Bellek applies spaced repetition to those words too. Combine imported lists with words you save while browsing.
