According to @claudeai on X, Claude for Word is now available to Pro and Max subscribers and works alongside Opus 4.7, enabling in-document drafting, revising, and analysis within Microsoft Word (source: Claude on X, Apr 17, 2026; product page: claude.com/claude-for-word). According to Anthropic’s product page, the integration streamlines tasks like structured editing, citation insertion, and long-form summarization directly in Word, which can reduce manual editing time for legal, consulting, and marketing teams. As reported by Claude’s announcement, pairing with Opus 4.7 brings stronger reasoning and longer-context handling to enterprise document workflows, creating opportunities for firms to standardize proposal creation, policy updates, and RFP responses inside existing Microsoft 365 environments.
