Engilish↔French translation packaged with application with more translation packages available for download.
Argos Translate supports installing model packages which are a zip archive with an ".argosmodel" extension that contain an OpenNMT CTranslate model, a SentencePiece tokenization model, a Stanza tokenizer model for sentence boundary detection, and metadata about the model. Pretrained models can be downloaded here (https://drive.google.com/drive/folders/11wxM3Ze7NCgOk_tdtRjwet10DmtvFu3i). To install a package click "Manage packages" from the toolbar in the GUI and select your package file.
Argos Translate also manages automatically pivoting through intermediate languages to translate between languages that don't have a direct translation between them installed. For example, if you have a es -> en and en -> fr translation installed you are able to translate from es -> fr as if you had that translation installed. This allows for translating between a wide variety of languages at the cost of some loss of translation quality.
