Introduction
We’re introducing a new way to stay informed about document changes in Word. The Activity tab in the Copilot summary now provides a dynamic snapshot of recent comments and edits, helping users quickly catch up on what’s changed.
When this will happen
General Availability (Worldwide): We began rolling out in late July 2025 and expect to complete by late August 2025.
How this will affect your organization
When users open a Word document, they’ll see a new Activity tab in the Copilot summary at the top of the document. This tab displays a summary of recent changes and comments. Users can filter activity by time window:
- Since last visit
- Past 3 days
- Past week
- Past 2 weeks

What you need to do to prepare
No action is required. This feature will be on by default. You may wish to inform users about this new capability to help them take full advantage of it.
