DeepL Translate is the most accurate translation tool compared to human translators. It's accuracy is due to its ability to understand the context of phrases and words, and its ability to imitate the workings of the human brain. It's also quick and nuanced, making it a good balance between efficiency and accuracy. While machine translation can be efficient, human translation is still necessary for accurate and nuanced translations. The accuracy of machine translation depends on the language pair being translated, with frequently used language pairs having a higher accuracy rate. However, even with advanced machine translation algorithms, the accuracy of machine translation is still doubted. Human translators are still needed for their ability to pick up on the intricacies of linguistics and implement their own experiences and gut feelings to do a job well. Human translation is still the goto choice for accurate and nuanced translations, but AI-assisted human translation can be a good balance depending on the project.
