What is Microsoft 365 Copilot?
Microsoft 365 Copilot connects enterprise work data and reasoning AI directly inside Word, Excel, PowerPoint, Outlook, and Teams.
Microsoft 365 Copilot embeds generative AI capabilities into daily workplace tools, grounded in enterprise organizational data through Work IQ. Rather than functioning as an isolated chat interface, it operates directly inside desktop, mobile, and web versions of Word, Excel, PowerPoint, Outlook, OneNote, and Teams. The system relies on Work IQ, a workplace intelligence layer that unifies company content, metadata, semantic indexing, line-of-business connectors, and Copilot Memory. This enables users to query business files, synthesize meeting transcripts, generate slide decks, analyze spreadsheets, and draft emails without copying context across disparate tools. In addition to in-app assistants, Microsoft 365 Copilot provides collaborative features like Copilot Cowork for complex multi-step tasks, Copilot Notebooks for organizing and analyzing cross-project assets into podcast-style audio summaries, and ready-to-use agents like Researcher, Analyst, and Facilitator. Custom agents can also be deployed through Agent Builder and Copilot Studio. Security is aligned with Microsoft Purview, Entra ID, and Enterprise Data Protection standards. Prompts, organizational inputs, and outputs inherit existing tenant permissions, sensitivity labels, and retention rules, and are not used to train underlying AI foundation models.
Deep, native integration with Microsoft 365 applications, grounded in tenant-wide documents, emails, and meetings via Work IQ while preserving strict Microsoft Purview enterprise permissions.
