Vocab helps you save, understand, and revisit useful words while you read the web — so vocabulary learning happens naturally, without interrupting what you're doing.
Articles, documentation, newsletters, forums — you meet useful words every single day. You look one up, understand it for a moment, and keep reading.
…and forget it five minutes later. Vocab closes that gap.
The whole learning journey, inside the pages you already read.
Meet an unfamiliar word while reading, on any site.
Get the meaning, translation, pronunciation, and examples — in context.
Save it instantly, together with the sentence it came from.
Vocab recognizes the word again on every page you visit.
Repeated exposure makes the word familiar — then yours.
Real screenshots from the actual extension — the words on this page are the ones Vocab learns from.
Select any word or phrase and the Vocab card appears right where you're reading: the word, its translation, and one-click actions. Save it — with the sentence, the source, and a note — without copy-pasting into a separate vocabulary app.
Right-click, press Ctrl+Shift+S, or use the popup. One keystroke is enough.
Don't just translate a word — understand how it's actually used. Vocab gives you the meaning, translation, IPA pronunciation with audio, part of speech, examples, synonyms, and a simple explanation, all built around the sentence you found it in.
One click generates the full enrichment for the word in front of you.
Once a word is saved, Vocab can recognize it whenever it appears again — on any page you visit — and highlight it for you. Hover a highlight to see the meaning, pronunciation, and the note you left.
Recall happens passively, as a by-product of reading.
As you save and enrich words, Vocab's Radar generates related vocabulary from them — synonyms, opposites, collocations, and word forms — each with a reason it's useful to you.
See a word you want? Save it and it joins your vocabulary. Your Radar grows as you learn.

Vocab removes the steps between encountering a word and actually learning it.
Learning happens where you're already reading — with nothing extra to do.
No study sessions. No stopping reading. No lists to build by hand. Just keep reading — Vocab turns the words you naturally meet into vocabulary you keep.
Vocab works with your preferred AI provider — OpenAI, OpenRouter, Google Gemini, Anthropic, and more — for richer explanations of the words you save. Bring your own key and stay in control. No key? Saving, highlighting, and translation work with none at all.
AI only runs when you ask for it.
Select a sentence and hit X-Ray Reading. Vocab lays the text open — its structure, the grammar that matters, the real meaning in context, and the choices the writer made.
