The Stack / Chat Assistants
Microsoft Copilot
02 DecisionsYes if your operation runs on Microsoft 365 — Copilot working inside your actual mail, spreadsheets, and meetings does what no external assistant can reach. If you're not a 365 shop, there's no reason to enter this ecosystem for the AI alone; the assistant seat market is stronger outside it.
The job in the stack
The Microsoft-side seat: AI woven through the 365 suite, for operations that live in Outlook, Excel, and Teams.

Questions operators ask
?Copilot Pro or M365 Copilot Business?
Pro is for individuals — Copilot inside Office apps on a personal plan. Business ($18–21/user) grounds the AI in your company tenant: shared mail, files, and meetings. If a team relies on it, tenant grounding is the whole point — buy Business.
