Microsoft 365 Copilot Review (2026)

Microsoft 365 Copilot in 2026 is the assistant for organizations standardized on Outlook, Teams, Word, Excel, PowerPoint, and SharePoint. Copilot spans the productivity apps (drafting in Word, modeling in Excel, summarizing Teams calls, triaging Outlook), Copilot Pages (collaborative AI canvas), and Copilot Studio (low-code platform for building custom agents). The Microsoft Graph integration is the moat — Copilot reads your real org data with respect to permissions. As a raw assistant it trails ChatGPT and Claude, but in Microsoft-heavy enterprises it's the right choice.
