What does FirstEdit actually do to my document?

FirstEdit runs a first-pass edit for you. It makes changes for you just as if you sent your document to a quality control team. In practice, that means it:

1. Checks every word and phrase against your house style rules.
2. Makes high-confidence corrections directly
3. Flags uncertain cases as comments rather than making a guess — these are handed to your human reviewer to decide.
4. Leaves everything else alone. Tone, argument, structure, and any judgment call that requires context all remain untouched.

How you approve or reject changes depends on how you access FirstEdit:

• If you use FirstEdit on a Word document then its edits will appear as tracked changes in the returned document so you can review and accept them. 
• If you use FirstEdit in the browser then there is a review screen where you can approve or reject each change.
• If you use FirstEdit on plain text, it supplies an audit log so you can see everything it has done.
