The Vocabulary Builder for ESL Learners
Learning English as a Second Language (ESL)? You already read English every day — articles, emails, social media, work documents. Bellek turns that reading into real vocabulary growth. Highlight any word on any webpage, get instant English definitions with translations into your native language, save with one click, and master with smart flashcards. Stop forgetting the words you look up.
Most ESL learners encounter unfamiliar English words every day — in articles, emails, social media, and work documents. The typical response? Open a new tab, Google the word, read the definition, and forget it by tomorrow.
If you want to actually remember, you'd need to copy the word into a flashcard app, add the definition, paste the context, and pick a deck. That's a 30-second interruption for every single word. So most people don't bother.
Bellek collapses that entire workflow into a single click. Select the word, see the definition and translation, click save. Done. Under 2 seconds. Your reading never stops. And unlike basic dictionary extensions, Bellek works on mixed-language pages too — English articles with Japanese, Arabic, or Spanish words are handled automatically.
Select any word on any website. The popup appears instantly with the English definition, synonyms, and examples.
See it translated into your preferred language — right in the popup, alongside the English definition. 20 languages supported.
Save it with one click. The word is captured with the full sentence context, source URL, difficulty level, and translation — in under 2 seconds.
Add your own notes — a memory cue, a usage note, or your own definition in your language.
Translations in 20 Languages: Set your preferred language in Settings (change anytime). Every English word you look up gets translated automatically — Turkish, Spanish, French, German, Arabic, Japanese, Korean, and 13 more. Translations are saved with the word for review. Free: 3 translations/day. Premium: unlimited.
Instead of studying disconnected word lists, Bellek lets you build vocabulary from the content you already read:
Every word you save carries the exact sentence where you found it. When you review a word later, you see how it was actually used — not just an abstract definition.
