Starting on build 23493, Windows 11 introduced the first official preview of the upcoming Windows Copilot experience. "Windows Copilot" or "Copilot" is the new AI chatbot the company is building to replace Cortana on laptops, tablets, and desktop computers.
The chatbot is technically the Bing Chat experience with support for third-party extensions with a deeper integration into Windows 11 that allows the AI to perform additional tasks, including changing system settings. However, the Copilot is not a part of the operating system. Instead, it's a feature of the Microsoft Edge browser that has been modified to appear as if it was a native feature of Windows 11.
