What it does
DeepL Translator turns text from one language into another, detecting the source language for you. The site lists more than 100 languages and says it runs on a language model trained on proprietary data by language experts. You can also drag in PDF, Word (.docx) and PowerPoint (.pptx) files for translation that keeps the original formatting and layout. Speech translation comes through DeepL Voice, for real-time conversations in virtual meetings or in person. Business features include glossaries, rules and a feature called Clarify, plus enterprise security and customization pages. DeepL Write, a separate product, adjusts style and tone in writing. The service is offered in many places: desktop apps for Windows and Mac, apps for iPhone, iPad and Android, extensions for Chrome, Firefox and Edge, add-ins for Word, PowerPoint, Outlook and Google Workspace, and an API with developer documentation and a free API key. A headline on the page says DeepL is now available inside Microsoft Copilot, ChatGPT and Claude through MCP. The page says over 200,000 businesses use DeepL and features customer stories from companies such as Merck KGaA and Hitachi Industrial Equipment Systems. It offers a free translator, a free Windows app download and a free trial, but does not state plan prices.
