What it does
An OpenNMT-based translation library that runs with no network at all, installing language pairs as self-contained model packages, usable as a Python library, a CLI or a GUI — and widely embedded elsewhere, including as the engine behind LibreTranslate. Quality trails the big commercial services, particularly on distant language pairs like English–Japanese, which is the trade for never sending the text anywhere. MIT.
