CAT Tools for Translators

As businesses continue to expand their global reach and individuals connect across cultures, the demand for high-quality translation services has never been greater. In this pursuit of linguistic excellence, Computer-Assisted Translation (CAT) tools have emerged as invaluable allies for translators, streamlining their workflow, enhancing productivity, and ensuring the utmost accuracy in their work.

In this article, we will take a look at the best CAT tools for translators, and break down their best (and worst) features so that freelance translators can make the most informed choice.

What Are CAT Tools?


CAT Tools for Translators

CAT tools, or Computer-Assisted Translation tools, are specialized software applications designed to aid translators in their work by facilitating the translation process, improving efficiency, and ensuring consistency in the output. CAT tools are not automatic machine translation systems like Google Translate; instead, they provide human translators with a set of powerful features to work more effectively with the texts they are translating.

Key features of CAT tools include:

  • Translation Memory (TM): CAT tools utilize a translation memory database that stores previously translated segments (sentences or phrases) along with their corresponding source texts.
  • Terminology Management: CAT tools enable translators to manage terminology databases, ensuring the consistent use of specific terms across different documents or projects. This feature is especially crucial for maintaining brand identity and industry-specific jargon.
  • Real-Time Editing: CAT tools display the source and target texts side by side, allowing translators to make adjustments on-the-fly as they work through the content.
  • Translation Collaboration: CAT tools often support collaboration features, enabling multiple translators to work on the same project simultaneously. 
  • Quality Assurance: CAT tools include built-in quality assurance checks to identify potential errors, inconsistencies, or formatting issues in the translated content. This ensures that the final output meets high-quality standards.
  • File Format Support: CAT tools are designed to handle a wide range of file formats, including Word documents, Excel sheets, PowerPoint presentations, HTML files, and various other formats commonly used for translation projects.
