Copilot in OneDrive can compare up to five selected files, helping reviewers identify differences and similarities without opening each document separately. Potential uses include checking contract versions, comparing vendor quotes, reviewing applications, and examining changes between financial reports.

Compare Shared Document Versions with OneDrive Copilot

On the OneDrive website, select the files and choose the Copilot comparison option. Review the resulting comparison in the context of the original documents before making decisions. The feature described by Microsoft works with files rather than images or videos, which are not supported for this comparison workflow.
