Select (highlight) any word on any webpage and the definition popup appears automatically. No clicking, no keyboard shortcuts — just select text. For English words, you'll see a full definition with synonyms and examples. For words in other languages, you'll see a translation into your preferred language.
When the popup appears, click "Save Word." The word is saved with the full sentence context from the page, the source URL, difficulty level, and — if translations are enabled — a translation into your preferred language. The entire process takes under 2 seconds.
Yes. You can look up unlimited words without ever saving any. Saving is completely optional — only save the words you actually want to learn.
Yes. Every word has a notes field in the popup where you can type your own definition, memory cue, usage note, or anything else. This is especially useful for rare words that may not have a dictionary entry, or when you want to capture how a term is used in a specific field or context.
For studying flashcards, yes — use the dashboard or scan the QR code to open your mobile study URL. But to look up and save words while browsing, you need the Chrome extension on desktop.
Bellek provides English definitions (powered by Merriam-Webster and Free Dictionary) with synonyms, examples, and part of speech. You can then translate any word and its definition into 20 languages: Turkish, Spanish, French, German, Italian, Portuguese, Russian, Arabic, Japanese, Korean, Hindi, Chinese, Dutch, Polish, Swedish, Thai, Ukrainian, Vietnamese, and Indonesian.
Set your preferred language in Settings (or accept the auto-detected suggestion — you can change it anytime). After that, every word you look up shows a translation into your language right in the popup alongside the English definition. When you save a word, the translation is stored too. Free users get 3 translations per day. Premium users get unlimited.
Yes. If you select a word on a French, Spanish, Turkish, or any other website, Bellek will translate it into your preferred language. You won't get a full English-style definition, but you'll get the translation — often exactly what you need when reading in another language.
Yes, anytime. Go to Settings in the extension and change your preferred language. Bellek auto-detects your browser language on first use, but you're never locked in.
The free version includes everything you need to get started:
Premium removes all limits and adds powerful study modes:
Try it free for 7 days — no credit card required.
All plans include a 7-day free trial. No credit card required to start.
You can continue looking up words (unlimited), but you can't save new ones until you either delete some or upgrade to Premium. You can always export your words, clear your collection, and start fresh.
Yes. Cancel anytime from your dashboard. If you cancel during your free trial, you won't be charged. After that, you'll have access until the end of your billing period. Your words stay accessible within free plan limits, and you can always export everything via CSV.
Bellek's mobile experience is a browser-based web app. From your dashboard on desktop, scan a QR code to generate your unique sync URL. Open that URL on any phone, tablet, or device to study your saved words with flashcards and quizzes. No app download required — works in any mobile browser.
It's simple:
Yes. Create collections to organize words by topic, subject, book, language, or any category. Examples: "IELTS Prep," "Medical Terms," "French Reading." Free users get 3 collections. Premium users get unlimited.
Yes. Export your deck as a CSV file, then import it into Bellek. The importer auto-detects formats from Anki, Quizlet, and generic spreadsheets. Free accounts support up to 30 words. Premium supports unlimited.
Yes. Your data belongs to you. Export your vocabulary as CSV files anytime — use them in other apps, spreadsheets, or as a backup.
Bellek uses spaced repetition algorithms to show words right before you're about to forget them. Words you know well appear less often. Words you struggle with appear more frequently. This optimizes your study time so you focus where it matters.
Free: Flashcards with spaced repetition.
Premium adds: Multiple Choice Quiz mode and Smart Review (focuses only on words you've marked as difficult or keep getting wrong).
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.
When you save a word, Bellek captures the full sentence where you found it. This is how your brain naturally remembers vocabulary — through context and usage, not isolated definitions. When you review a word later, you see exactly how it was used in real content.
Yes. Your vocabulary data stays in your browser's local storage. We don't sell your data, track your browsing, or show ads. Export and delete anytime. Privacy-first by design.
No account required for basic use. Your data is stored locally in your browser. For mobile sync, you'll generate a unique URL via QR code from your dashboard.
