Enterprise-grade neural machine translation, AI writing refinement, and real-time voice translation across thirty-plus global languages.
Translates whole PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), and HTML files up to 30 MB (Individual/Team) or 100 MB (Business/Enterprise) while keeping original fonts, tables, slides, and visual formatting intact.
Ensures consistent brand and technical terminology across language pairs using CSV-importable shared glossaries, automated glossary generation, shared style rule lists, and translation memory.
Enhances original drafts and translated copy with real-time sentence rewrites, word alternatives, and one-click tone adjustments (e.g., Business, Academic, Casual, Diplomatic) via browser, desktop, and Microsoft 365/Google Workspace add-ins.
Provides real-time spoken language translation and live multilingual captions for video conferences and mobile in-person dialogues, with 30 minutes per user per month included in paid DeepL Pro plans.

Deep-learning auto-correction for 40+ languages, deployable on-premise
The engine goes beyond flagging mistakes: it rewrites typos, phonetic errors, fused or split words, elisions, and non-native mistakes automatically.
Neural models cover languages from French, English, and Spanish to Arabic, Hindi, Turkish, Ukrainian, and many more, with varying corpus sizes per language.
Deploy NeuroSpell within your own infrastructure so that no data is sent outside your intranet.
The engine detects and protects named entities such as people, places, and acronyms so they are not wrongly altered.
