MateCat is a free, web-based computer-assisted translation tool with machine translation, translation memory and open-source heritage.
MateCat gives professional translators a full CAT environment in the browser at no cost: machine translation pre-translation, translation memory that learns from your work, terminology management and quality checks. It handles large files and many formats, supports real-time collaboration across translators, and integrates with the MyMemory database for matches. Built by the team behind translated.net, it remains free for professionals, monetized through translation services.
MateCat is completely free for translators and agencies; the business model runs through paid human translation services.
