Anthropic has launched Claude for Word, a public beta add-in that embeds Claude directly inside Microsoft Word as a sidebar, with all AI-suggested edits appearing as native tracked changes. Available to Claude Team ($25/seat/month) and Enterprise subscribers, it targets legal professionals with features like contract review, clause flagging, redlining, and comment resolution. The tool integrates with Claude for Excel and PowerPoint for cross-document workflows. The launch follows Anthropic's February 2026 legal plugin for its Claude Cowork platform, which triggered a $285 billion single-session market cap wipeout across legal tech companies including Thomson Reuters, RELX, and Wolters Kluwer. Key open questions include professional liability risks — highlighted by a hallucinated citation submitted by Anthropic's own counsel in a 2025 court case — and competitive implications for legal AI specialists like Harvey, which uses Claude as an underlying model but has no plans to incorporate the Word add-in.
