Overview
Claude for Word is Anthropic's native sidebar plugin for Microsoft Word, currently in beta for Team and Enterprise subscribers. It brings Claude's advanced reasoning directly into Word documents, letting users draft, edit, and analyze content without leaving their workflow. In the growing landscape of AI writing assistants, it takes a distinctly document-centric approach.
What sets it apart from generic AI assistants is how it handles edits. Every change Claude makes appears through Word's built-in Track Changes system, so users review and accept modifications one by one rather than losing control of their document. For professionals who work with contracts, regulatory filings, or multi-author reports, this alone solves a major trust problem with AI editing tools.
Key Features
Track Changes editing — All AI-generated edits appear as tracked revisions in Word, letting you accept or reject each change individually without overwriting your original text.
Comment-aware responses — Claude reads inline comments and discussion threads in your document, then generates targeted edits that address each piece of feedback directly.
Format-preserving drafting — Maintains heading hierarchies, numbered lists, defined terms, and cross-references when generating or restructuring content, avoiding the reformatting cleanup most AI document generator tools typically require.
Reusable Skills — Save common workflows like contract review checklists or status report templates as standardized team processes that any member can run with one click.
Cross-app context — Can share context with Claude for Excel and Claude for PowerPoint across open files in a single conversation, after cross-app support is enabled.
Citation pinpointing — When answering questions about your document, Claude provides clickable section citations that point to the relevant location in the document.
How to Get Started
Check your plan — Claude for Word requires a Claude Team plan starting at $20 per seat/month billed annually ($25 billed monthly, five-seat minimum) or an Enterprise plan. Free, Pro, and Max plans do not include Word integration.
Install the add-in — Open Word, go to Insert > Get Add-ins, search for "Claude by Anthropic for Word" in Microsoft AppSource, or open the Claude for Word Marketplace listing directly, then install the add-in.
Sign in — The Claude sidebar appears on the right. Sign in with your Anthropic account credentials tied to your Team or Enterprise workspace.
Start working — Highlight text or type a prompt in the sidebar. Claude reads your full document context and delivers edits through Track Changes. Accept, reject, or modify each suggestion as you normally would.
Note: Claude for Word supports .docx and .docm files only. Legacy .doc and .rtf formats must be converted first. Available on both Mac and Windows.

How It Compares
| Feature | Claude for Word | Microsoft Copilot | ChatGPT |
|---|---|---|---|
| Word integration | Sidebar plugin with Track Changes | Native, deepest integration | No native Word support |
| Price | Team: $20/user/month billed annually or $25 monthly (5-seat minimum); Enterprise self-serve: $20/seat + usage | Varies by Microsoft 365 Copilot SKU, prerequisite license, and billing option | $20/month for ChatGPT Plus (no native Word add-in) |
| Editing approach | Track Changes for every edit | Inline generation and rewriting | Copy-paste workflow |
| Document understanding | Strong at legal numbering, cross-refs | Pulls context from emails, meetings | General-purpose, no Word context |
| Best for | Contract review, regulatory docs | Daily office work across M365 | Cross-platform AI assistance |
Claude for Word targets a different niche than Copilot. Claude for Word is a document-centric add-in focused on tracked edits inside Word. Verify current Microsoft 365 Copilot app coverage, licensing requirements, and Graph-grounding behavior separately before making a direct comparison. Teams in specialized fields like AI contract review will find Claude's Track Changes approach more aligned with their existing workflows than Copilot's inline generation.
Best For
- Legal teams reviewing contracts, NDAs, and regulatory filings who need Track Changes for audit trails
- Financial analysts working with 10-K reports, earnings summaries, and multi-section compliance documents
- Research teams collaborating on long-form papers that require consistent formatting and cross-references
- Enterprise departments standardizing document workflows across team members using reusable Skills
- Developers already using Claude Code who want the same AI quality extended to their documentation workflows
- Organizations already using Claude Team or Enterprise who want AI assistance without switching tools
