DeepL

Overview

DeepL is a German AI language company best known for its high-quality machine translation, widely considered the most natural-sounding translator for European languages. Its product family spans four lines — DeepL Translator (text/document translation), DeepL Write (AI writing assistant), DeepL Voice (real-time speech translation) and the DeepL API for developers. DeepL is trusted by professional translators, global enterprises and e-commerce teams who need accurate, secure multilingual content.

Key Features

• DeepL Translator: neural machine translation with industry-leading accuracy and fluency, supporting document translation (Word, PDF, PPT, Excel), image/text-in-file translation, web, desktop, browser-extension and mobile apps, custom glossaries for consistent terminology, and translation history.
• DeepL Write Pro: AI writing assistant that corrects grammar, optimizes word choice and enhances clarity/style in English, German, French and Spanish — with style and tone controls, and instant support inside Microsoft 365, Google Workspace and across the web.
• DeepL Voice: real-time voice-to-voice translation. Voice for Meetings works inside Microsoft Teams, Zoom Meetings and Google Meet (web, desktop and mobile); Voice for Conversations handles face-to-face speech and is included in the Voice for Meetings Business plan.
• DeepL API: REST API for Translate, Write and Voice (including real-time voice-to-voice and transcription), letting developers build multilingual experiences into products, CAT tools and enterprise workflows.
• Integrations: native add-ins for Microsoft Word/Outlook/PowerPoint, Google Workspace, browser extensions (Chrome, Firefox, Edge), desktop apps (Windows/Mac) and mobile apps (iOS/Android); plus a growing ecosystem of AI-agent and workflow integrations.
• Data security: Pro customer data is never used to train DeepL's models; texts are deleted immediately after translation on applicable plans, with encryption and enterprise-grade compliance standards.
• Team & enterprise features: SSO, team administration, usage controls, saved/favorite translations and Customization Hub for enterprise tailoring.
