What translate5 is
translate5 is an open-source translation management system for coordinating translation projects and collaborative workflows. It includes translation memory, terminology management, quality checks, and alignment tools. translate5 AI supports translation, post-editing, review, pre-translation, and automated quality estimation with cloud or on-premises language models. translate5 Visual adds live layout previews, comments, annotations, and print approval workflows; TermPortal provides centralized glossary management with images, cross-references, TBX import and export, and proposal and approval workflows.
The system integrates with DeepL, Google and Microsoft machine translation, several LLMs, CAT formats, Plunet, GroupShare, and WorldServer. Its user-interface functions are available through a REST API, and it supports plug-ins, external services, and standalone components. Deployment options include shared or private cloud, on-premises, hybrid, and multicloud.

The downloadable version is free but excludes several plug-ins, including AI, Visual, InstantTranslate, TermPortal, and the DeepL Connector.
