ChatGPT arrives in Word: free for all plans, enterprises get two weeks of GPT-5.6 Sol at no charge

OpenAI launched an official ChatGPT plugin for Word: a sidebar that rewrites selections, compresses drafts, fixes formatting, unifies terminology, and edits in track-changes mode — free across all plans worldwide via Microsoft Marketplace. Paid tiers can pull in Outlook/SharePoint/Google Workspace context and save reusable Skills. Catches: free users get the fast GPT-5.6 Luna (not Sol); Business/Enterprise get a Sept 17-30 free Sol preview; Word bills by token on API rates and shares quota with Codex. Default-on for workspaces arrives Oct 1, 2026. With Excel (May) and PowerPoint (July), OpenAI completes the Office trio 5 months after Anthropic — and one Word window now hosts three competing AIs: Copilot, Claude, and ChatGPT.
