What is Microsoft 365 Copilot?
It’s understandable to feel confused by the term “Copilot” — Microsoft uses it in several contexts. From Copilot+ PCs to web-based Copilot experiences and integrated tools within Microsoft apps, the name can refer to different things depending on the setting.
Microsoft 365 Copilot specifically refers to the AI-powered assistant embedded within Microsoft 365 apps like Word, Excel, PowerPoint, Outlook, and Teams. Designed to streamline productivity, it helps users draft documents, analyze data, create presentations, summarize meetings, and manage emails.
This version of Copilot also integrates with Microsoft Graph and Copilot Chat, enabling a more personalized and context-aware experience across Microsoft 365 services.
