Notes 
TranslateLocally is an open-source desktop application that performs neural machine translation entirely on your computer using Bergamot/Mozilla translation models. No text is ever sent to a server. It supports Windows, macOS, and Linux, and integrates with Firefox and Chrome through a browser extension for in-page translation.

A hardened pick. Worth the effort once you have chosen to shrink your footprint on purpose. Enough for most people. Threat levels
Our take
Running translation models locally is a genuine privacy guarantee rather than a policy promise: if text never leaves your device, it cannot be logged or mined. The Bergamot engine produces quality that holds up well for the languages it covers, particularly European language pairs. The catch is coverage: the model library is narrower than a cloud service, so if you regularly translate between less-resourced languages you may find gaps. It is the right tool for anyone who translates sensitive documents and cannot accept text leaving their machine, and for privacy-conscious developers who want a local translation API.
