OmegaT

OmegaT is a free and open-source Java-based application that aims to help professional users translate documents fast and easy. It integrates numerous options that might take a while to figure out.

Installation is not necessary, as long as Java is installed on the computer. You can drop the app directory in any location on the hard disk and just click the JAR file to run. Another possibility is to save OmegaT to a USB flash disk or similar storage unit, in order to run it on any PC easily.

The GUI consists of a seemingly outdated window that shows instructions on how to get started, divided into multiple panes like instant start, fuzzy matches and glossary.

To create a new project it is necessary to specify the saving directory (an empty one) and configure settings pertaining to the languages of the source and translated files, sentence-level segmenting, tags removal, and file locations (e.g. glossary, dictionary, translation memory).

Source files can be easily imported from the disk, while URLs can be added from MediaWiki webpages. It is possible to create glossary entries by adding comments, source and target terms, build alternative translations, insert or replace words with matches, change the text case, insert source tags, jump to specific segments, validate tags, and more.

As far as app settings are concerned, you can select the translation service (e.g. Microsoft, Google), change the font, view and edit file filters, enable an automatic spellchecker, use proxies if necessary, as well as to modify the default name/ID that marks your team name for translations.

OmegaT is low-demanding when it comes to CPU and RAM, so it does not hog system resources. It has a good response time and did not hang, crash or pop up error messages in our testing. On the other hand, its interface and options are not intuitive at all, making it quite difficult to work with. Users have more luck resorting to friendlier apps for executing professional translations between multiple languages.
