BitVocab Highlighter

Highlight English words you don't know yet as you read on the web, based on your BitVocab mastered-words list.

BitVocab Highlighter marks unfamiliar English words on any web page, so you can read real content and focus only on the words worth learning. How it works: • Sign in with your BitVocab account (password or Google) • It loads your personal "mastered words" list • Click "Highlight" on any English page — words you don't know are highlighted, words you've already mastered are skipped • Turn on "Phrases" to also underline common English phrases and fixed expressions alongside word highlighting • Hover a highlighted word to mark it as mastered; it syncs back to your BitVocab account Scroll freely — newly shown text is highlighted as you go Export to Word: Turn any highlighted page into a study sheet. Click "Export Word" and choose exactly what to include — the word, phonetic spelling, star rating, and meaning — laid out as a grid with adjustable columns. Or switch to "with examples" mode to get real example sentences for each word, with the target word picked out in the sentence. Extra filters: highlight only IELTS / TOEFL / AWL vocabulary, filter by word frequency level, and exclude proper nouns (people, countries, places). Your mastered-words list is shared across BitVocab on the web, mobile, and this extension. Tip: build your list quickly at bitvocab.com first, then maintain it as you read. Your privacy matters: the text of the pages you read is processed locally in your browser and never sent to our servers. Learn more at bitvocab.com
