What is Microsoft 365 Copilot?

Microsoft 365 Copilot adds an AI assistant inside Word, Excel, PowerPoint, Outlook, Teams and the wider Microsoft 365 apps. Because it works through Microsoft Graph, it can reason over your organisation's mail, files, chats and meetings, so requests like summarising a thread or drafting from a shared document use real work context. It is sold as a per-user add-on on top of an existing Microsoft 365 subscription rather than as a standalone product. The differentiator is that grounding: it acts inside the tools and data a company already runs on.

FAQ

Do I need a separate subscription?

Yes. Copilot is sold as a per-user add-on on top of a qualifying Microsoft 365 business or enterprise plan. It is not included with consumer Microsoft 365 subscriptions.

What data does Copilot use?

It works through Microsoft Graph, so it can use your mail, files, chats and meetings, subject to your existing permissions. It cannot see content you do not already have access to.

Where does it help most?

Summarising long threads, drafting documents from existing material, recapping meetings and reasoning over spreadsheets. Value depends heavily on how organised and permissioned your tenant is.
