User Reviews

  • good

  • Free CAT - excellent experience

  • Great job.

  • Great update.

  • I'd say OmegaT is the best CAT tool I've ever used. Yes, Trados is packed with features but even the basic operations are just too clumsy. OmegaT is very simple and straight forward. Editing the glossary (or making one from Excel) can't get any easier. With Trados it takes complex steps using different applications, loading data into containers... etc.. too clumsy. I have wasted too much time trying to get Trados to work properly. It gives you errors everytime you try to generate an output file. Hours and hours of precious time wasted looking for workarounds. With OmegaT, I can get things DONE very quickly, period. I highly recommend OmegaT to freelance translators who want to start getting productive.
