What OmegaT is
OmegaT is a free, open-source translation memory application for professional translation work. It provides fuzzy matching, match propagation, team translation features, autocomplete, and simultaneous processing for multi-file projects. User glossaries recognize inflected forms, and multiple translation memories can be used at once. The application supports more than 30 formats, including LibreOffice and Microsoft Office documents, XHTML, HTML, PO files, and plain text. TMX and XLIFF support helps exchange work with other translation memory tools, while interfaces connect to machine translation services. Additional tools include Unicode, regular-expression searches, custom tags, right-to-left language support, and language-dependent spelling and grammar checks. OmegaT runs on Windows, macOS, and Linux, and other systems capable of Java 11. It requires Java Runtime Environment 11 or later. The project says it does not collect information or store it online without consent; configured external services may receive shared data. GPL v3 permits use, modification, and redistribution.
