Offline neural translation library and app you install and run locally
Argos Translate is an open-source neural translation tool that runs on your own machine. You install it as a Python package or desktop application, download model packages for the pairs you need, and translate text, files or folders without sending anything to a server. It is built on an open translation stack and is one of the engines behind LibreTranslate, the self-hosted translation API that lets organisations add translation to internal systems while keeping documents on their own network. Model quality is below the largest commercial engines, and every pair must be downloaded, but the offline and self-hosted properties are the point.

Yes, once the language model packages have been downloaded. That is the point of the project and the reason it turns up in environments where documents cannot be sent to a cloud service at all.
Understandable but not polished. For internal reading and getting the gist they are usually adequate; for published or customer-facing text a larger commercial engine or a human reviewer remains the safer choice.
LibreTranslate is a self-hosted translation API that uses Argos Translate as one of its engines. Teams wanting an HTTP service rather than a Python library often deploy it that way.
