Microsoft Copilot is a chatbot developed by Microsoft and launched on February 7, 2023. Based on a large language model, it is able to cite sources, create poems, and write songs. It is Microsoft's primary replacement for the discontinued Cortana. The service was introduced under the name Bing Chat, as a built-in feature for Microsoft Bing and Microsoft Edge. Over the course of 2023, Microsoft began to unify the Copilot branding across its various chatbot products, cementing the copilot analogy. At its Build 2023 conference, Microsoft announced its plans to integrate Copilot into Windows 11, allowing users to access it directly through the taskbar. In January 2024, a dedicated Copilot key was announced for Windows keyboards.
