Le matin, le marché du quartier s’anime avant même l’ouverture des boutiques. Les maraîchers installent leurs étals, et l’odeur du pain chaud flotte déjà dans la rue. On y vient pour faire ses courses, mais surtout pour prendre des nouvelles des voisins.

English translation: In the morning, the neighbourhood market comes to life before the shops have even opened. Growers set up their stalls, and the smell of warm bread already drifts down the street. People come to do their shopping, but mostly to catch up with their neighbours.

One sentence, both sides

Point at a sentence and its counterpart lights up in the other language.

A word, in this sentence

Hold the key over a word. With Precise translation, you get its meaning in this sentence, not a dictionary list.

The same French article with the reveal key held over the word “attrait”: a small card reads “attrait · In this sentence”, “appeal, draw”, “here: what makes it attractive”, and that paragraph’s English translation sits in the margin — A sample page; the note was written for this image.

Where your data goes

By default, translation runs on Chrome’s built-in on-device model, so page text stays on your computer.
Precise translation sends paragraphs straight to your chosen provider, only when you ask; your key stays in the extension’s IndexedDB.
It runs only on sites where you turn it on, or on every site once you turn on “Available on every site”.
No account, no analytics, no data collection. In Incognito windows it saves no translations, terminology or per-site layouts.

FAQ

What do I need to run it?

Desktop Chrome 138 or later. Turning on a language pair downloads Chrome’s language pack once; after that the pair works on every site, because translation runs in the extension’s own hidden document. Local files work too, once you turn on “Allow access to file URLs” for it in chrome://extensions .

Which key do I hold?

⌥ on Mac, Shift on other systems. You can also assign a shortcut for switching modes at chrome://extensions/shortcuts .

Is it free?

Yes. On-device translation is free, with no account or subscription. Precise translation uses your own API key, so the provider bills you for it.
