About

Stop forgetting the words you look up.

Bellek is a smart vocabulary builder that turns passive reading into active learning in any language. If you've ever looked up a word and forgotten it five minutes later, this vocabulary builder is for you. 

Highlight any word on any webpage to get the definition, synonyms, and the translation into your native language instantly. Save it with one click. Bellek captures the source url and the original sentence as context so you always remember where you found it. 

Whether you're expanding your English vocabulary, studying for IELTS or TOEFL, reading in a foreign language, or collecting words that catch your eye — this vocabulary builder gives you one place to save, organize, study, and actually remember them. 

Bellek is the browser dictionary and vocabulary tracker that replaces scattered word lists, note-taking apps, and translation tools: everything in one place.

🌍 ENGLISH DEFINITIONS + TRANSLATIONS IN 20 LANGUAGES

Highlight any English word to see its definition, synonyms, and translation in your chosen language instantly.

Reading in another language? Bellek detects the page language automatically and translates any word into your chosen native language. Reading a Japanese blog and need it in Turkish? Browsing a Spanish article and want it in German? Set your native language once and Bellek handles the rest.

Supports 20 languages including Turkish, Spanish, French, German, Italian, Portuguese, Russian, Arabic, Japanese, Korean, Hindi, Chinese, Dutch, Polish, Swedish, Thai, Ukrainian, Vietnamese, and Indonesian.

🧠 FLASHCARDS, QUIZZES & SPACED REPETITION

This vocabulary builder doesn't just save words, it helps you actually learn them. Study with flashcards using spaced repetition, test yourself with multiple choice quizzes, or focus on your weak spots with smart review. Track your streak and mastery level for every word. Built for real vocabulary retention, not just word collecting.

📂 ORGANIZE YOUR VOCABULARY
