OmegaT is a free translation memory application written in Java. It is a tool intended for professional translators. It does not translate for you! (Software that does this is called "machine translation", and you will have to look elsewhere for it.)

To install OmegaT, run the following command from the command line or from PowerShell:

C:\> choco install omegat

To upgrade OmegaT, run the following command from the command line or from PowerShell:

C:\> choco upgrade omegat

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
