What the hack is a "Microsoft 365 Copilot Bizchat"?

First, we had Bing Chat Enterprise, which was Microsoft’s free AI offering. Then came Microsoft Copilot, also a free AI solution. After that, Copilot for Microsoft 365 was introduced (now called Microsoft 365 Copilot), which is the paid version of Microsoft’s AI.

When the paid version launched, Microsoft 365 Business subscribers (not Personal users) were able to switch between Work and Web modes at the current URL: https://m365.cloud.microsoft/chat 

The Work mode is still referred to as Business Chat, where queries are grounded in your organization’s data. The Web tab, on the other hand, remains the freely accessible chat experience within Microsoft 365 Copilot.
