What it is

Matecat is a free, open-source online computer-assisted translation tool for translators, language service providers, companies, and enterprise teams. It uses translation memories and machine-translation matches to reduce the text translators need to translate, and offers adaptive machine translation from ModernMT in more than 200 languages. The tool supports document and website translation, glossary tools, and real-time teamwork: teams can assign jobs, discuss work in comments, and divide projects among translators. Matecat states that it supports 80 file formats, while the hosted service works with XLIFF out of the box and other formats may require Matecat Filters. REST APIs let users create projects and check their status; API credentials require contacting support with a use description. Its open-source server can be self-hosted. For hosted use, Matecat says browser-to-server communications use SSL, originals and translations are stored long term, and public segments may provide matches to others. It runs in a desktop browser, not on mobile devices. The listed plan is free, with unlimited features, users, and projects.
