Build your vocabulary from everything you read. Bellek turns everyday studying into active learning — save words with one click, study with smart flashcards, and actually remember what you look up.
Strong vocabulary helps you write more clearly, understand reading materials faster, participate confidently in class, and use the right terminology in exams. The problem is most students learn words once and never review them again.
Bellek turns everyday studying into a vocabulary learning system — whether you're discovering words while reading or reviewing your own lists.
When you encounter an unfamiliar word in articles, textbooks, research sources, or learning platforms, select it. Bellek shows the English definition with synonyms and examples instantly. Add your own notes (a memory cue, a professor's explanation, your own phrasing), then save with one click. The word is captured with the full sentence context, source page, and difficulty level.
International Students: Translations in 20 Languages — If English isn't your first language, set your preferred language and see translations alongside every definition. Turkish, Spanish, French, German, Arabic, Japanese, Korean, and 13 more. Change anytime in Settings.
Bellek isn't only for language learning. You can import any list of terms and definitions via CSV and review them as flashcards with spaced repetition. Examples: biology terms, psychology vocabulary, history keywords, economics concepts, literature themes.
Built on proven algorithms that show words right before you'd forget them. Difficult terms appear more often. Easy ones fade back. Moves vocabulary into long-term memory. Free for all users.
