What it does
yunit picks a handful of unfamiliar words on every page you read, sets a small gloss above each, and leaves the rest of the sentence untouched. It works on articles, novels in plain HTML, video transcripts, drafts in another tab, the long Wikipedia paragraph you’ve been meaning to finish.
Select any word or phrase yourself to translate it on the spot. A single click keeps it in your collection.
On keeping what mattered
yunit captures the surrounding sentence, the language pair, and the date, then brings the word back to you when it’s worth revisiting. Your collection grows quietly between sessions: a commonplace book of the vocabulary you have chosen to remember.
