Artificial intelligence, and generative AI (GenAI) in particular and Large <\/span>Language Models (LLMs), have gone beyond the experimental stage of <\/span>2023-2025. In 2026, <\/span>AI has become the driving force behind the changes in the translation<\/a> industry<\/b>.<\/span><\/p>

This transition raises existential questions about the nature of language work, shifting the added value from raw production to strategic validation, risk management, and cultural engineering.<\/span><\/p>

However, despite the rise of LLMs and machine translation, a human touch remains essential<\/a> when it comes to localization. In order to ensure the quality of their work and streamline their processes, many translation professionals <\/span>use computer-assisted translation (CAT) tools<\/b>.\u00a0<\/span><\/p>

When choosing a CAT tool, it can be difficult to make sense of this complex ecosystem. In this article, you will find <\/span>a comparative table of the main CAT tools on the market<\/b>, which will help you make an informed choice.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Difference between CAT tools and Machine Translation (MT)<\/strong><\/h2>

Firstly, a little reminder: unlike machine translation, which requires no human intervention and is based on statistics or a neural model, <\/span>computer-assisted translation is translation that is carried out by a human, but with the help of software<\/b>. <\/span><\/p>

These software programs have a host of features – translation memories, glossaries, quality control tools, etc. – which facilitate the translation process, ensure the terminology is consistent and improve productivity. <\/span><\/p>

So even in the age of AI, CAT tools remain essential for professional localization workflows, particularly in certain regulated and specialist sectors such as medical, technical and legal translation<\/a>.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
