Microsoft Copilot
Microsoft Copilot is Microsoft's AI assistant brand spanning consumer, prosumer, and enterprise use cases. At the consumer end it's a free web and Windows AI chat. At the enterprise end it's deeply embedded in every Microsoft 365 app — Word, Excel, PowerPoint, Teams, Outlook — with agentic capabilities that can take multi-step actions on your behalf. Copilot Studio lets businesses build custom agents on top of the same platform.
