Microsoft 365 Copilot review

Microsoft 365 Copilot ranks third because, for a Microsoft shop, it puts AI where employees already write, calculate and meet. The Copilot Business add-on is listed at $18 per user per month billed annually, down from $21, and adds Copilot inside Word, Excel, PowerPoint, Outlook and Teams, chat grounded in work data with a choice of language models, and the Researcher and Analyst agents. It also opens Cowork, Autopilot and advanced AI features in apps such as SharePoint, and gives admins analytics on adoption and impact under Enterprise Data Protection. Companies that also need the Office apps can buy Business Standard with Copilot at $23.50 or Business Premium with Copilot at $32. Even without a license, Copilot Chat is included with eligible Microsoft 365 plans. The trade-offs are lock-in to the Microsoft stack, a promotional headline price, and usage-based billing for some advanced AI features.

Who it is for

Companies that already run on Microsoft 365 and want the assistant inside the apps staff use every day.
