💡 Pro tip: Most tools offer free trials or free tiers. Test 2-3 options side-by-side to see which fits your workflow best.
Yes. The AI Rewriter is part of Microsoft 365 Copilot, which is a paid add-on on top of a base Microsoft 365 subscription. For businesses, Copilot for Microsoft 365 costs $30 per user per month (annual commitment), while individual consumers can access Copilot Pro for $20 per month. Without a Copilot license, the rewriter and other generative features are not available in Word, though basic Editor suggestions (grammar and clarity) remain free.
Grammarly focuses primarily on grammar, spelling, and style corrections with limited generative rewriting, while QuillBot is a dedicated paraphrasing engine. Word's AI Rewriter is powered by GPT-4 class models and lives natively in the document, so it understands the full context of what you are writing — including headings, comments, and surrounding paragraphs. It is more powerful for long-form generative rewriting but typically pricier than Grammarly Premium ($12/month) or QuillBot Premium (~$9.95/month).
No, not for commercial Microsoft 365 customers. Microsoft's enterprise data protection commitments state that prompts, responses, and organizational data processed by Copilot are not used to train foundation models. For consumer Copilot Pro users, different terms apply, so you should review the Microsoft Services Agreement. This enterprise data boundary is one of the primary reasons regulated industries choose Copilot over general-purpose alternatives.
Copilot in Word supports more than 20 languages, including English, Spanish, French, German, Italian, Portuguese, Japanese, Simplified Chinese, and Korean, with Microsoft expanding language coverage on a rolling basis. Rewriting quality is strongest in English but remains competitive in major European and Asian languages. Some advanced features may roll out to English first before other languages catch up.
No. The AI Rewriter requires an active internet connection because the rewriting is performed by Microsoft's cloud-hosted Azure OpenAI models, not locally on your device. It works in Word for the Web, Word for Windows, Word for Mac, and the Word mobile apps, but each request round-trips to Microsoft's servers. Offline Word documents can be edited normally, but the AI features stay disabled until connectivity is restored.
