The Brain / Compare / Microsoft 365 Copilot alternatives
2026Updated 15 September 2026
The 10 best Microsoft 365 Copilot alternatives for a mid-sized company.
Microsoft 365 Copilot is the suite's own copilot: drafting in Word, summarizing in Teams, reasoning over mail and calendar through Microsoft Graph, at $18 per user per month. This list is based on public product information, not a controlled test.

The short answer
Stay with Copilot when the work stays inside Microsoft 365 and the price on the invoice is the whole decision. Look elsewhere when the record that matters lives beside the suite, in the CRM, the tickets or the billing system, and nothing watches across them.

Which one, and when
When to stay with Microsoft 365 Copilot
Your estate is Microsoft 365
The work starts and ends inside Word, Excel, Outlook and Teams.
The price is on the invoice
$18 per user per month on the Business add-on, list $21, is a known number.
You will build in Copilot Studio
Agents on Graph are your team's to build and own.
When to switch
The record lives beside the suite
The deal is in the CRM, the ticket in the desk, the invoice elsewhere.
Nobody watches across systems
Copilot Chat waits for a question; the stalled work never asks one.
You want a person in front of writes
A documented yes before anything sends, on every system, not one.
Microsoft 365 Copilot alternatives, asked plainly
What is the closest Microsoft 365 Copilot alternative for a mid-sized company?
Gemini for Google Workspace is the closest like-for-like: a suite copilot, included in the suite's Business plans. Notion AI is the closest at a published per-seat price outside a suite. The Brain is the alternative when the work spans Microsoft 365 and the systems beside it, and someone must be told before they ask.
Is there a cheaper Microsoft 365 Copilot alternative?
Copilot publishes $18 per user per month on the Business add-on, promotional to 31 December 2026, list $21. Gemini for Google Workspace is included from Business Starter, which is cheaper only if you already run Workspace. Notion AI is $20 per member per month and Dust starts at 24 euro per month. The Brain is a two-week Sprint, then $30K to $100K fixed, not a per-seat price.
Can the Brain replace Microsoft 365 Copilot?
No. The Brain does not replace a suite or the copilot inside it; it does not draft in Word or summarize a Teams call. It sits on Microsoft 365 and the systems beside it, reads what changed, and asks a person before it writes. Keep Copilot for the work inside the apps.
