What is OmegaT?
OmegaT is a robust, free, and open-source translation memory (TM) application designed for professional translators. It functions across Windows, macOS, and Linux operating systems, providing a comprehensive environment for managing and executing translation projects. Unlike machine translation software, OmegaT does not automatically translate text; instead, it leverages translation memories, glossaries, and fuzzy matching to assist human translators in achieving consistency and efficiency.
The tool supports over 30 file formats, including common office documents like Microsoft Office Word, Excel, and PowerPoint, as well as web formats like XHTML and HTML, and open standards like OpenDocument Format. It is ideal for translators who require powerful features such as simultaneous processing of multiple-file projects, multi-TM usage, and integration with machine translation services, all within a customizable and community-driven platform.
Available on: Windows, macOS, Linux

OmegaT FAQ
How does OmegaT handle different linguistic complexities like inflected forms in glossaries?
OmegaT's user glossaries are designed with advanced recognition capabilities, allowing them to identify and suggest terms even when they appear in inflected forms within the source text, significantly improving consistency for languages with rich morphology.
Can OmegaT be used in conjunction with commercial machine translation engines or web services?
Yes, OmegaT includes an interface that allows it to connect with various machine translation and neural machine translation software or web services. This enables translators to leverage MT suggestions alongside their translation memories and glossaries.
What specific exchange formats does OmegaT support for interoperability with other translation memory tools?
OmegaT is highly compatible with other translation memory applications through industry-standard exchange formats such as TMX, TTX, TXML, XLIFF, and SDLXLIFF, facilitating seamless data transfer and collaboration across different CAT tools.
Given its open-source nature, how does OmegaT ensure the quality and currency of its integral spelling checker dictionaries?
OmegaT utilizes Hunspell dictionaries for its integral spelling checker. These are the same widely-used dictionaries found in other major software like LibreOffice and Mozilla Firefox, ensuring a high standard of linguistic accuracy and regular updates through the broader open-source community.
What are the options for users who want to contribute to the OmegaT project but are not programmers?
Non-programmers can contribute significantly to the OmegaT project in several ways, including authoring documentation, localizing the user interface and help texts into new languages, testing weekly builds to identify bugs, and promoting the tool through articles or reviews.
