DeepL vs Smart Assistant by Mailbutler

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.

Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.

Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.

The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.

Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
