Should I Use Microsoft 365 - Sign into Copilot?
Microsoft 365 includes Word, Excel, PowerPoint, Outlook, Teams, and OneDrive, with Microsoft Copilot built in to help you create, communicate, and summarize information. Formerly Office 365.
Depends
DependsBuy it if your team already lives in Outlook, Teams, and Office files — Copilot adds real drafting and summarizing on familiar ground.
The default office suite, now with built-in AI. Worth it if you live in Office/Teams; overkill for occasional doc editing.
