Microsoft 365 Copilot
Founder, Automation Squad
Situational
Ranked #4 of 10 AI assistants & chat
$21
Copilot is not a standalone product — that's the single most important thing to understand before you budget for it. It's a $21/user/month add-on (promotional pricing through September 30, 2026 for orgs under 300 seats; standard price $30/user/month for Enterprise) sitting on top of a Microsoft 365 E3, E5, Business Standard or Business Premium license you're already paying for. Real all-in cost per seat is usually $60-90/month once you add the base plan.
Standout feature: Deepest hooks into Outlook, Word, Excel and Teams of any assistant here — if your company already runs Microsoft 365, it shows up where you already work.
The verdict
Microsoft 365 Copilot earns a SquadScore of 64.8/100 (situational), ranking #4 of 10 AI assistants & chat we’ve scored at $21. Deepest hooks into Outlook, Word, Excel and Teams of any assistant here — if your company already runs Microsoft 365, it shows up where you already work.
Scored by the published SquadScore v1.0.0 methodology from vendor-published specs, August 2026.
Pros
- Prompts are not used to train Microsoft's foundation models — a strong default for regulated industries
- Governed access inherits your existing Microsoft 365 permissions, so IT doesn't rebuild access control from scratch
- Deepest native integration into Word, Excel, Outlook and Teams of anything on this list
Cons
- Cannot be bought on its own — you need a qualifying M365 base license first, which most vendor comparisons conveniently leave out of the headline price
- $21/seat promotional pricing is time-limited (through Sept 30, 2026); standard price is $30/seat for Enterprise
- Feature rollout is genuinely uneven across apps — Excel Copilot still lags Word and Outlook

microsoft.com's own Copilot page didn't surface a clean pricing table on fetch; the $21/$30 figures come from Microsoft's Business plans-and-pricing page as reported across multiple July 2026 sources, with the $21 explicitly flagged as promotional (standard $21 vs a further-discounted period ending Dec 31 2026 per some sources — treat the exact promo mechanics as needing a live-quote confirmation). Context window left null: Microsoft doesn't publish a single token figure for Copilot on its marketing or pricing pages, since the underlying model varies by task and app. Rewired to the categories.ts eight-spec schema: securityTier is 'SOC 2 + SSO + audit' — Copilot runs under Microsoft's SOC 2 Type II program, inherits Entra ID SSO from the underlying M365 tenant, and Purview-based audit logging covers Copilot interactions; we found no evidence of a signable BAA/HIPAA commitment automatically bundled at this tier, so we stopped one rung short of 'enterprise + HIPAA'. connectorSupport is 'MCP + agent actions' — Microsoft has GA'd MCP support directly inside Word/Excel/PowerPoint/Outlook and Teams-channel agents, which already take actions (e.g. scheduling a meeting from Jira/GitHub/Asana context pulled via MCP), not just reading. integrations is 100 — Microsoft's own connectors-gallery page (learn.microsoft.com/microsoft-365/copilot/connectors/connectors-gallery) states 'more than 100 prebuilt connectors' across Microsoft- and partner-built galleries; recorded at 100 since the spec tops out there. appCoverage is 'web + desktop + mobile' — Microsoft ships the Copilot app for Windows, Mac, iOS and Android. setupEffort ('IT ticket', editorial) reflects that Copilot can't be bought standalone and Microsoft's own rollout guidance typically calls for an IT-led Purview/oversharing review before turning it on.
Corrected Aug 16, 2026no change, deliberately. microsoft.com lists the Copilot Business add-on at $18.00/user/mo annual, but that is a promotion running 2026-07-01 to 2026-09-30 and applying to the first year only; the standard rate is $21 and that is what a buyer pays ongoing. Recording the promo would understate real cost and would expire inside this row's own re-check window.
