Is it a good idea to use Microsoft’s genAI free tool Copilot when you write documents in Word?

write. Anyone can get writing help from Microsoft’s Copilot genAI tool via the free Copilot web or mobile app. But Copilot becomes especially useful when it’s integrated with various Microsoft 365 apps.”  The December 16, 2025 article entitled " Microsoft Copilot can boost your writing in Word, Outlook, and OneNote — here’s how” (https://www.computerworld.com/article/3479705/how-to-use-microsoft-copilot-for-writing-in-microsoft-365-word-outlook-onenote.html) included these comments “Who can use Copilot in Microsoft 365 apps”:

If you have a Microsoft 365 Personal, Family, or Premium subscription, Copilot access in Word, OneNote, Outlook, and other Microsoft 365 apps is built into your plan. But Microsoft 365 business and enterprise subscriptions do not include Copilot integration in the apps. Your company has to purchase an additional Microsoft 365 Copilot plan, which costs $30 per user per month when paid annually. (Microsoft does offer plans that bundle the M365 apps and M365 Copilot, but the costs are the same.)

This guide goes over how to use Copilot in Word, Outlook, and OneNote to help you compose, revise, and summarize text. I’ll demonstrate using Copilot with an individual Microsoft 365 Premium account, but most of the steps and user interfaces are similar under a Microsoft 365 business plan. I’ll also note additional features that are available only under the business versions of Copilot and Microsoft 365.

Note: Microsoft 365 apps aren’t completely consistent on different platforms, so you might see a somewhat different interface for a feature than is shown here. What’s more, some features are available in the web apps but not the desktop apps, and vice versa — and if you have a work or school Microsoft 365 account, your administrator may allow some Copilot tools but not others.
