# DeepL

> DeepL is an AI-powered translation service that consistently outperforms competitors in natural language quality. Used by professionals, translators, and businesses for accurate, nuanced translation in 31 languages.

DeepL is widely recognized as the highest-quality AI translation service available — consistently beating Google Translate, Microsoft Translator, and other competitors in blind human evaluations for naturalness and accuracy. DeepL's neural translation engine was trained on a massive curated corpus of professionally translated documents, giving it a deep understanding of linguistic nuance, idiomatic expressions, and domain-specific terminology that makes its output feel like it was written by a native speaker rather than translated. DeepL Translator supports 31 languages and is available as a web app, desktop app (Windows and Mac), mobile app, and browser extension. Documents (DOCX, PPTX, PDF) can be uploaded and translated with original formatting preserved. DeepL Pro adds features for professional and business use: unlimited text translation, document translation, the DeepL API for developer integration, a CAT tool plugin for professional translators (SDL Trados, MemoQ), and glossary management for enforcing consistent terminology translations. DeepL Write is a separate product for native language improvement — an AI writing assistant that rewrites sentences in the same language to improve clarity, tone, and naturalness. It functions like Grammarly but with a stronger focus on rephrasing. Used by major law firms, multinational corporations, and professional translators, DeepL has established itself as the professional standard for AI translation, particularly for European languages where it has the deepest training data.
