Overview
- Anthropic launched Claude for Word in beta Saturday, with access limited to Team and Enterprise customers.
- The add-in lives in a Word sidebar and preserves styles and numbering while offering tracked changes, comment-driven edits, and answers with clickable citations.
- Users can switch between Anthropic’s Sonnet 4.6 and Opus 4.6 models and share context across Claude for Excel and Claude for PowerPoint to avoid copy‑paste hops.
- Anthropic warned that documents can hide prompt‑injection instructions and advised human review, saying the tool should not finalize client deliverables, litigation filings, or audit‑critical papers.
- Coverage highlights an intentional play for lawyers and finance teams and frames the move as a challenge to Microsoft’s Office stronghold and to legal‑tech vendors built around contract drafting and review.
