Microsoft 365 Copilot ends where the suite ends.

Copilot is on the invoice, inside Word, Excel, Outlook and Teams, grounded in Microsoft Graph, from public product information, not a controlled test.

The short answer

Copilot is the incumbent in Microsoft 365, drafting in Word, summarizing in Teams, and reasoning over mail and calendar through Graph. The Brain instead holds one memory across Microsoft and the systems beside it, and waits for a person before it changes anything.

FAQ

Questions buyers ask

Is Microsoft 365 Copilot or WorkElate Chief better for a 500-person company?

If the work stays inside Microsoft 365, Copilot, and it is probably already in your agreement. If the work starts in Teams and lands in a CRM, a ticketing tool or a finance system, the Brain, because it holds one memory across all of them. A 500-person company usually has both kinds of work; count which one leaks.

Can I use Microsoft 365 Copilot and the Brain together?

Yes, where Microsoft 365 records something the Brain can read. The Brain reads what a connected system emits, and mail, calendar and Teams are such systems; connecting it is engagement work in the Sprint, not a switch in a settings page.

What does Microsoft 365 Copilot cost?

Microsoft publishes $18 per user per month for the Business add-on, billed yearly, as a promotional price to 31 December 2026; the list price is $21. It is an add-on to a Microsoft 365 plan you already pay for.

What does the Brain cost?

A two-week Diagnostic Sprint first, then a fixed build of $30K to $100K on your stack. The Sprint fee is not published; it is scoped on the first call, and the build price is fixed before it starts.
