In the Office apps, in pounds. Check the data boundary.
Microsoft Copilot sits inside Word, Excel, PowerPoint, Outlook and Teams, drafting, summarising and analysing against the documents and mail your organisation already holds, with Copilot Studio for building custom agents on top. The consumer Copilot Pro subscription has been retired from sale and folded into a broader consumer bundle, with existing subscribers supported only until August 2026, so the business add-on is the relevant product now. It bills in pounds. On agents, Copilot is a host rather than a server: Microsoft publishes separate MCP servers for various services, but Copilot itself consumes them rather than exposing one, and the newer workload connectivity is licence and administrator gated.
The argument is proximity rather than capability: Copilot is not the strongest assistant available but it is the one that can see your actual documents, spreadsheets and mail without anyone pasting anything, and for a large organisation that usually beats a better model you have to copy into. Pound pricing and existing enterprise agreements make procurement straightforward. Two things worth knowing, and the second is the important one. Copilot is an MCP client rather than a server, so despite its AI positioning it is not something other agents can call, which is easy to miscategorise. And on data: Flex Routing can now run inference outside the EU Data Boundary at times of peak demand, and it is on by default, while models supplied by third parties are excluded from that boundary entirely. If your organisation relies on the data boundary for compliance, that needs checking and potentially turning off rather than assuming.
Best for: Organisations already standardised on Microsoft 365 where the documents and mail are the context that matters.
