Translation that doesn’t spy on you
Every time you paste text into Google Translate, that text is sent to Google’s servers. For a holiday phrase, who cares. For a contract clause, a medical letter, a private message, or anything covered by an NDA, it’s a real problem — you’ve just handed confidential text to a third party.
This translator is different. It uses the on-device AI translation model built into your browser (Chrome and Edge, version 138 and up). Your text is translated locally, on your own machine, and is never sent to any server— not ours, not Google’s. After the language pack downloads once, it even works with the internet switched off.
How on-device translation works
Modern Chromium browsers ship a small, efficient translation model that runs directly on your device. The first time you translate a given language pair, the browser downloads that pair’s model (typically a few tens of megabytes) and caches it. Every translation after that is instant and offline.
What to do if your browser isn’t supported
Safari and Firefox don’t yet expose the on-device translation API. If you’re on one of those, the tool shows a one-click link that opens Google Translate with your text pre-filled — handy, but be aware that path does send your text to Google. For the private, on-device experience, open this page in Chrome or Edge.
When to use a private translator
- Translating legal, medical, or financial documents
- Anything under an NDA or confidentiality agreement
- Personal messages you’d rather not log to a third party
- Working offline — on a plane, in a dead-zone, on a locked-down network
