Langmosis

Select a word as you read, translate it on your device, and save it with its sentence and source to your own vocabulary list.

Langmosis turns reading into vocabulary. Select a word on any page — it's translated on your device and saved with the sentence it came from, the page title, and the link. One gesture, no popup to dismiss. Why install it • Learn from what you actually read, not from flashcard decks. • Keep the context — every word remembers the sentence and page you met it on. • On-device and private — no account, no server, nothing leaves your browser. Uninstalling deletes it. Your words, three places • Side panel — your reading list beside the page; review, edit, and see words saved on the current page. • New tab — a quiet home that brings back words due for review, with a translate box and your frequent sites. • In place — saved words stay underlined on the pages where they appear. Requires Chrome 138+ (built-in on-device Translator API).
