Microsoft gives your Word documents an AI co-author you didn’t ask for

Microsoft has released agentic Copilot capabilities across Word, Excel, and PowerPoint, enabling the AI assistant to directly edit documents and spreadsheets rather than just suggest changes. The feature defaults to on but requires explicit user activation. The rollout continues Microsoft's strategy of embedding Copilot throughout its products, though it faces criticism for forced integration and concerns about autonomous AI actions in user documents.
