What is DeepL Translator?
DeepL Translator is a machine translation product from DeepL that converts typed text, uploaded files and images between more than 100 languages. It runs on a language model that the company says was trained on proprietary data with input from language experts. Documents in common formats such as PDF, Word, PowerPoint and Excel can be dropped into the translator and come back with their layout kept. Professional features include glossaries, rules and a Clarify function for controlling terminology and tone. The translator is reachable in a browser, through desktop programs for Windows and Mac, mobile apps for iPhone, iPad and Android, browser extensions, and add-ins for Microsoft 365 and Google Workspace. It sits alongside related DeepL products for writing, real-time voice translation and a developer API, and it can be called from AI assistants over MCP.
