Microsoft Copilot

Microsoft Copilot is really several products sharing one name, and telling them apart is most of the buying decision. Free Copilot at copilot.microsoft.com and in Edge gives AI chat, web search with citations and image generation at no cost. Copilot Chat, included with eligible business Microsoft 365 subscriptions, adds commercial data protection but reads only public web data. Paid tiers are what put Copilot inside Word, Excel, PowerPoint, Outlook and Teams with access to your own files. The most common outdated figure online is Copilot Pro at $20 a month: Microsoft stopped selling it to new customers in October 2025 and folded its features into Microsoft 365 Premium at $19.99, with existing subscriptions ending renewal in August 2026. On the business side, Microsoft 365 Copilot is an add-on requiring a qualifying base licence, so the real cost is the Copilot fee stacked on a subscription you already hold.
