Lexi — Translate & Save While You Read

Double-click any word to translate it into your language and save it to a personal vocabulary deck.

Just double-click any word and Lexi instantly shows the translation in your language — right where you're reading, with no tab-switching and no copy-paste. See a word worth remembering? Click Save. Lexi builds a personal vocabulary deck from the words you actually encounter, complete with the sentence each word came from, so you learn in context. Review your saved words any time as simple flashcards from the toolbar. ■ WHY LEXI • Instant inline translation — double-click a word or select a phrase, get the meaning on the spot. • Learn in context — every saved word keeps the real sentence it appeared in. • Built-in flashcard review — turn the words you meet into words you know. • 100% private — translation runs on your device using Chrome's built-in AI.

Pick your native language once. 2. Double-click any word on a web page. 3. See the translation instantly, and click Save to add it to your deck. 4. Open the toolbar popup to review your saved words as flashcards. ■ PRIVACY FIRST Lexi uses Chrome's on-device translation, so the text you translate is never sent to any server — not ours, not anyone's. Your saved vocabulary is stored only in your own browser. No tracking, no analytics, no ads. Note: Lexi runs on regular websites (http/https). Like all extensions, it cannot run on Chrome's internal pages (chrome://) or the Chrome Web Store. Requires desktop Chrome 138 or newer.
