Microsoft Copilot is Microsoft's AI assistant. Its big draw is where it lives: inside Windows and the Microsoft 365 apps you may already use, Word, Excel, Outlook, Teams. It can act on your documents and emails in place.
Like the others it is a generative AI tool. For businesses on Microsoft 365 it is often a paid add-on per user. The Academy focuses on Claude, but Copilot is the natural fit for deep Microsoft shops.
