Computer-Assisted Translation (CAT) refers to the use of software tools to aid human translators in the translation process. These tools help improve efficiency and consistency by providing features like translation memory, which stores previously translated segments for future use, and terminology databases that ensure the correct use of specific terms. CAT tools do not replace human translators; instead, they enhance their capabilities. By streamlining repetitive tasks and allowing for better collaboration, CAT helps translators focus on the nuances of language and context, ultimately leading to higher-quality translations. Popular CAT tools include SDL Trados, MemoQ, and Wordfast.
