Language Studio™ has the unique ability to focus on very narrow domains that as a result deliver very high quality translations. When customizing an engine, the quality is not just derived from the data that is in the engine, but also the data that is not in the engine. For example, mixing Anti-Virus domain data with Medical domain data will provide mixed output from two different contexts when talking about a virus. As a result, the output will be unpredictable – this is a common complaint from many MT systems. Language Studio™ is able to reduce this issue considerably by using very clean data that is focused on a narrow domain.

The difference in the result can be seen in the following two translations that came from the same Spanish source text, but were translated with two different engines that were customized for the Business domain and the Children's Books domain:
