What is Copilot for Microsoft 365 AI?

Copilot for Microsoft 365 is an AI assistant built into your existing Microsoft 365 applications, including Word, Excel, PowerPoint, Outlook, and Teams. It uses large language models to help with writing, analysis, and summarisation tasks without requiring you to switch between tools. The assistant works alongside your actual documents and data, meaning it understands context from files you're already working on. It's designed for organisations that want AI capabilities integrated into their everyday workflow rather than as a separate product.
