DeepL is a translation service made by DeepL SE, a company based in Cologne, Germany. It launched its translator in 2017. It grew out of Linguee, an online dictionary run by the same team. Many users choose it because its translations read naturally.
DeepL translates text and whole documents such as Word files, PowerPoint files and PDFs while keeping the layout. It covers dozens of languages. DeepL Write helps people improve grammar and style in their own text. DeepL Voice translates speech in meetings and conversations. It runs on the company's own models. Glossaries let companies keep names and terms consistent across documents.
The free version has limits on text length and document uploads. DeepL Pro plans raise those limits and promise that texts are not stored or used for training. Businesses can connect it to their own software through the DeepL API. Law firms, publishers and global companies are among its users.
