About Microsoft 365 Copilot

Microsoft 365 Copilot brings AI directly into the apps your company already lives in. It drafts in Word, builds models and charts in Excel, generates entire PowerPoint decks from a brief, summarizes Outlook threads, and recaps Teams meetings — all grounded in your tenant data via the Microsoft Graph. The Work IQ personalization layer learns your communication style and relationships, while pre-built agents like Researcher, Analyst, and Facilitator extend Copilot into specialist work. Add Copilot Studio to build your own no-code agents.
