Overview

• Word, Excel, PowerPoint, Outlook and OneNote now include an in-app sidebar that answers questions, drafts content and analyzes tables.
• Microsoft says the integrated chat uses GPT-5 with its enterprise safety controls.
• The global rollout targets Microsoft 365 business customers who previously lacked an integrated Office chatbot at no extra charge.
• A separate Microsoft 365 Copilot license still offers cross-organization reasoning, file uploads, image generation, priority access and faster responses.
• Consumers saw an earlier Copilot launch with roughly a 30% price increase, and Microsoft maintains a classic non‑AI subscription for those who opt out.
