Four ways to look at it
Simple markup shows a clean page with a line in the margin where something changed. All markup shows every insertion and deletion. No markup shows the document as it would be with all changes accepted, and Original as it was before them.
Saved as Word saves it
Tracked changes are written into the DOCX the way Word writes them, and comments with their replies and resolved state go into the file's comments parts. So the changes you make here show up as tracked changes in common word processors, under your name.
Printing
With Print markup and comments turned on, printing the document includes its changes and a list of its comments. Your browser's print dialog can also save that as a PDF.
Private by design
A contract under review is exactly the kind of file you would rather not upload. It is read and written inside your browser tab and kept in this browser on your device.
Limits to know
- Formatting changes, such as making text bold, are not tracked.
- There is no live co-editing: reviewers exchange the file.
