Anthropic has introduced a new artificial intelligence-powered tool, Claude for Word, integrating its AI assistant into Microsoft Word to enable users to interact directly with documents, according to reports.
The feature, currently in beta, is available only to Team and Enterprise plan subscribers and is designed to support professional use cases such as legal reviews, financial memos and iterative document editing.
Anthropic stated in its listing on the Microsoft Marketplace that Claude for Word enables users to draft, edit and revise documents directly from a sidebar, while preserving formatting, numbering and styles. The tool is also capable of reading complex multi-section documents, processing comment threads and editing clauses within structured documents.
Among its key features, Claude for Word allows users to ask specific questions about a document, such as summarising commercial terms or locating particular clauses, with responses including clickable citations that navigate directly to relevant sections. The tool also supports semantic navigation, enabling users to identify provisions related to specific themes through natural language prompts.
The feature includes iterative editing capabilities, allowing users to select passages and instruct the AI to refine them, while maintaining surrounding formatting and structure. It also supports tracked changes, where edits appear as revisions within Word’s native review pane, enabling users to accept or reject modifications individually.

Claude for Word can also engage in comment-driven editing by reading and responding to comment threads, making changes to associated text and explaining its edits within the thread. Additionally, the tool offers cross-application functionality, sharing context with add-ins for Excel and PowerPoint, allowing users to pull data into documents or generate presentation summaries without manual transfer.
However, Anthropic has cautioned that the feature remains in beta and is not recommended for final client deliverables, litigation filings or documents containing highly sensitive information without human verification. The company has also highlighted risks related to prompt injection attacks, advising users to rely on trusted documents, as externally sourced files may contain hidden instructions that could manipulate the AI or extract sensitive data.
For individual users, installation requires accessing the Claude for Word listing on Microsoft Marketplace, selecting the installation option, activating the add-in within Microsoft Word and signing in with a Claude account.
For enterprise deployments, administrators are required to roll out the tool organisation-wide through the Microsoft 365 Admin Centre.
