Microsoft 365 Copilot Chat is an AI-powered chat application built to work within your Microsoft 365 environment. It’s designed to help your teams ask questions, get answers, and move work forward using natural language. Because it’s part of Microsoft 365, it fits into your existing business tools and workflows rather than sitting off to the side as a separate system. You can think of it as an AI assistant that helps you reimagine how everyday tasks get done across your organization.

Microsoft 365 Copilot Chat is described as a secure AI application that is grounded in the web and built for business use. In practice, this means it’s designed to align with the security and compliance standards you already expect from Microsoft 365. Because it runs within your Microsoft 365 subscription, it benefits from the same enterprise-grade security framework you rely on for email, documents, and collaboration. This allows you to rethink how you use AI at work while staying within a familiar, governed environment.

Microsoft 365 Copilot Chat is included with your existing Microsoft 365 business subscription at no extra charge. There is no separate line item or add-on fee required to start using it. This makes it easier to experiment, pilot, and gradually reshape how your teams work with AI, without having to justify a new standalone budget or negotiate a separate contract.
