Review AI changes

AI changes can be reviewed as a before-and-after comparison:

  • Red highlights - Removed text
  • Side-by-side view - Compare original and enhanced versions
  • Accept or reject - Choose whether to use it

Suggested edits from AI Chat

For changes that depend on a conversation rather than one selected passage, use the Edits control in AI Chat. Enable Suggest edits, describe the result you want, and review each proposed document change before it is applied.

This is useful for requests such as tightening an opening, correcting repeated terminology, or revising several separate passages while preserving your control over the final text.
