OmegaT
The free translation memory tool
OmegaT is a free, open-source translation memory application designed for professional translators. It addresses the need for a cross-platform tool that helps translators maintain consistency and efficiency by reusing previously translated content, without requiring a commercial license or subscription. The software is written in Java and runs on Windows, macOS, and Linux.
Its core capabilities include fuzzy matching, match propagation, and team translation support. Users can work with multiple translation memories and glossaries simultaneously, with recognition of inflected forms. The application supports over 30 file formats, including LibreOffice and Microsoft Office files, XHTML, HTML, PO localization files, and plain text. It offers full Unicode support, regex searches, custom tags, and an integral spelling and grammar checker. OmegaT is compatible with other translation memory tools through TMX and XLIFF formats and provides an interface to machine translation services.
OmegaT is intended for individual translators and translation teams. It is distributed under the GNU General Public License version 3.0, making it free to use, modify, and redistribute. There is no paid edition, free plan, or trial; the software is available for download directly from the project website.
