Argos Translate vs DeepL Translator

Argos Translate is a free, open-source Python translation library designed for offline use. It uses OpenNMT and can run as a Python library, command-line tool or GUI application. Language models are installed as .argosmodel archives, and the requested language pair must be installed before translation. Listed languages include Arabic, Chinese, English, French, Hindi, Japanese and Spanish, among others. When a direct pair is unavailable, Argos can route translation through an installed intermediate language, though this may reduce translation quality. Users can train and package custom language models. The maker describes LibreTranslate as an API and web application built on Argos Translate. A linked tool translates .txt, .odt, .odp, .docx, .pptx, .epub and .html files. The project is dual licensed under MIT or Creative Commons CC0. Argos Translate provides API access, supports Linux self-hosting and is associated with a community forum and machine-translation support or consulting services.

DeepL Translator translates text, documents, and websites, and includes translation memory, glossary tools, and API access. It supports 100 languages. Chrome, Firefox, and Edge extensions provide translation and writing improvements while browsing; listed integrations include Microsoft Word, Google Workspace, Microsoft 365, and AI agents. The Free version costs nothing and includes 50,000 characters per user each month, one file translation per month for files up to 5 MB, and one glossary with five entries per language pair. Individual costs €7.49 a month billed annually and includes a 30-day free period; it allows 300,000 characters monthly and three file translations. Team costs €24.99 a month billed annually, while Business costs €49.99 a month billed annually. Enterprise pricing is custom. DeepL lists TLS encryption and ISO 27001 and SOC 2 Type II certified processes and infrastructure. For Pro subscribers, content and results are temporarily stored only as technically needed and then deleted. Team administration is included in Team and available for Business and Enterprise users; single sign-on is available for those tiers. The maker was founded in 2017 and is headquartered in Cologne, Germany.
