argos-translate

Offline neural machine translation

TLDR

Translate text between languages

$ argos-translate --from-lang [en] --to-lang [es] "[Hello, world]"

Pipe input for translation

$ echo "[Text]" | argos-translate --from-lang [en] --to-lang [de]

Translate from a file

$ argos-translate --from-lang [en] --to-lang [fr] < [input.txt]

Install a language package (via argospm)

$ argospm install translate-[en]_[es]

List installed language packages

$ argospm list

Update the package index and search available packages

$ argospm update && argospm search --from-lang [en]

SYNOPSIS

argos-translate --from-lang code --to-lang code [text]argospm subcommand [options]

argos-translate is an open-source, offline translation tool based on OpenNMT neural machine translation models. It runs entirely on the local machine, providing privacy-preserving translation without sending data to cloud services.Languages are provided as downloadable packages named translate-_from_\__to_ (e.g. `translate-en_es`). Packages are managed with the companion argospm command, which supports update, search, install, list, and remove subcommands.

PARAMETERS

-f code, --from-lang code

ISO 639-1 source language code (e.g. `en`, `es`, `fr`).

-t code, --to-lang code

ISO 639-1 target language code.

-h, --help

Show help and exit.

CAVEATS

Language packages must be installed via argospm before translation works. Translation quality varies by language pair and may not match commercial services. First-run translations are slower due to model loading; subsequent calls in the same process are faster. Large documents are memory- and CPU-intensive.

HISTORY

Argos Translate was created by Argos Open Tech as an open-source, privacy-respecting alternative to cloud translation services, using CTranslate2 and OpenNMT models. It also powers the self-hosted LibreTranslate web API.
