What is Language Translator?
Translate text between 20 languages without sending a single word to a server. This translator uses your browser’s built-in on-device language models, so documents, emails and private messages are translated locally — something no cloud translation service can offer.
How to use Language Translator
- Choose the language you are translating from, or leave it on “Detect automatically”.
- Pick the language you want to translate into.
- Type or paste your text into the left box.
- Click “Translate”. The first use of a language pair downloads its model, which takes a moment; after that it is near-instant.
- Copy the translation, or use ⇄ to swap the languages and translate back.
Why use this tool?
Your text stays private
Cloud translators receive everything you paste. Because this runs on your own device, confidential emails, contracts and personal messages never leave your computer.
Works offline once downloaded
After a language pair’s model is cached, translation keeps working without an internet connection.
No usage limits
There is no character cap, daily quota or paid tier, because translation costs nothing to run on your own hardware.
Frequently asked questions
Which browsers support this?
On-device translation needs Chrome or Edge version 138 or newer on desktop. In other browsers the tool explains this rather than silently falling back to a cloud service that would upload your text.
Why is the first translation slow?
Each language pair downloads a model the first time you use it. Your browser caches it, so later translations in that pair start immediately.
Is it as accurate as Google Translate?
On-device models are smaller than the huge server-side ones, so long or highly technical passages may read less naturally. For everyday text the quality is good — and it is the only option that keeps your content private.
Is my text sent anywhere?
No. Only the language model is downloaded to your device; your text is never transmitted. You can verify this in your browser’s DevTools Network tab.
