Microsoft has changed its AI strategy, renaming Bing Chat to Copilot to better compete with ChatGPT. Originally launched as part of Bing, the AI interface was integrated directly into search results. However, less than a year later, Microsoft abandoned the Bing Chat brand in favor of Copilot, which was used in Bing, Microsoft Edge, and Windows 11.

The rebranding to Copilot came shortly after OpenAI reported that ChatGPT has 100 million weekly users. Despite Microsoft’s multi-billion dollar partnership with OpenAI, both companies are competing for the same AI assistant market. Microsoft’s Copilot is now positioned as a direct competitor for both consumer and business applications.

Colette Stolbaumer, general manager of Microsoft 365, explained that Bing Chat and Bing Chat Enterprise will now be called simply Copilot. This change follows the previous decision to use the Copilot brand for the chatbot in Windows 11. The rebranding also means a move to a more offline experience, with Copilot now available through a dedicated domain, similar to ChatGPT.

Business users will have access to Copilot with an Entra ID, while consumers will need a Microsoft account. Microsoft Copilot is officially supported in Microsoft Edge or Chrome browsers, as well as on Windows or macOS platforms.
