Microsoft Copilot review: the AI personal assistant for Microsoft 365 users
Answer in brief: If your email, calendar and documents live in Outlook and Office, Microsoft Copilot is the AI personal assistant that is already inside your apps. Every consumer Microsoft 365 plan, from Personal at $9.99/month, includes Copilot in Word, Excel, PowerPoint and Outlook. Premium ($19.99/month) adds the Researcher and Analyst agents and limited use of Cowork, which is in preview. A limited free Copilot app is available too. It ranks #4 overall.
Top pick for Office users: Microsoft 365 Premium. At $19.99/month it pairs advanced Copilot chat with extensive Researcher and Analyst usage, Audio Overviews and image generation, and more Voice and Vision usage.

An assistant where your work already happens
Copilot's advantage is that you don't need a new app. You can draft a reply in Outlook, summarize a long thread, turn notes into a Word document, or build a PowerPoint deck from an outline without switching tools. Microsoft says all four paid plans include extensive usage for Chat, Deep reasoning and Pages, plus priority access. Premium and Pro add agentic help: Researcher for multi-step research and Analyst for working with data.
Who it fits
- People and families already paying for Microsoft 365.

Why it stands out
- Built into Office on every consumer Microsoft 365 plan.

Honest drawbacks
- On Family and higher plans, the AI benefits belong only to the subscription owner and cannot be shared.
- Microsoft describes most limits in qualitative terms such as standard, extensive and highest, and says they may change.
- Cowork is in preview, only available in the US and Canada, and varies by platform and device.
- It adds less value outside the Microsoft ecosystem.
