Personal Review of OmegaT, its usefulness, advantages and shortcomings

OmegaT is my CAT tool of choice. It is an open source Computer-assisted Translation software tool available in the market since 2002. In addition to the traditional translation memory function, which is the standard function of most CAT tools, OmegaT provides dictionary and terminology building by the translator, and support of multiple files in translation projects, in a streamlined user interface that does not force itself on you or bloat your machine operating system as other famous computer tools of the trade. An elegant and light-weight application that neither deplete machine memory or the hard disk nor mess up user screen with interface components and features you might not want when you start using a CAT tool.

I was lucky that I started using CAT tools by OmegaT before the famous Trados that I still do not use daily. One advantage of OmegaT is interoperability. In most cases, it imports translation memory files that other tools create, lets translator use these, and saves them in their format to assist any colleague translator to continue the project and work and import them in their tool.

I have used OmegaT in several projects including text documents, web sites and pages and also comouter and mobile applications.
