Native Windows assistant with Vision and Actions that act across apps in realtime.
Microsoft Copilot is the most widely distributed product in this space by install base. Through Copilot Vision and Copilot Actions, the assistant can see what is on screen and carry out tasks across Windows applications and Microsoft 365.
The product is Windows-native and integrates deeply with the operating system. Email triage, document editing, spreadsheet manipulation, and meeting scheduling are all handled through natural language descriptions rather than direct manipulation. The Microsoft 365 integration means the agent can pull context across Word, Excel, Outlook, and Teams in a single task.
The Vision and Actions surface, shipped through 2025 and 2026, made Copilot a full desktop agent rather than a chat sidebar. For many Windows users, Copilot is the first agent they encounter on their own machine.
