AI assistant built into Word, Excel, PowerPoint, Outlook, and Teams that drafts, summarizes, and answers questions grounded in your Microsoft 365 data.

by Microsoft

What it does

Microsoft 365 Copilot embeds an AI assistant across the Microsoft 365 apps. In Word it drafts and rewrites documents, in Outlook it summarizes threads and drafts replies, in Excel it helps analyze data, in PowerPoint it generates slides from existing content, and in Teams it produces meeting recaps and action items.

Its core differentiator is grounding. Copilot draws on your organization’s emails, files, chats, and calendar through Microsoft Graph, and it respects the permissions users already have, so answers come from content each person is allowed to see. Microsoft also provides admin tooling and extensibility for connecting additional data sources and building custom agents.

Because it requires a qualifying Microsoft 365 subscription and is priced as a per user add-on, it makes the most sense for organizations already committed to the Microsoft stack. Rollouts typically involve IT-led permissions reviews before broad deployment.
