Version history for every document.
Documents keep their versions as you work. Compare any two, read a short summary of what changed, and restore an earlier one without losing anything in between.
How versions are kept
- A document saves itself as you type, and keeps a version every few minutes while you work.
- Ctrl S (⌘ S on a Mac) or Save now keeps a version straight away.
- Restoring an old version makes a new version, and loading someone else's newer changes keeps yours as a version first.
Each version records who saved it and when. Changes made by an agent or a connected AI tool are recorded under that agent or tool, not under you.
Open the history
Choose Version history from the document's More menu. Versions are listed newest first, with the current one marked.
Compare two versions
Press Compare and pick any two versions; they need not be next to each other. The comparison shows the changes side by side or in one column, with buttons to step from one change to the next and to expand the unchanged parts. A short AI summary at the top says what changed, in plain words.
Restore an earlier version
Choose Restore this version. Stable Baseline makes a new version with the old content, so nothing in between is lost and you can always go forward again.
Collaboration mode
When two people save
If someone else saves a newer version while you are editing, a note says who, and offers to load their version: keeping yours as a version first, or setting yours aside. If two saves clash, you can save yours as a copy, reload the latest version, or dismiss the warning. Nothing is overwritten without your say.
Whiteboards
Whiteboards keep versions too: save the current board as a version when you choose, and restore an earlier one from Version history in the canvas actions.
Plans and work items
Plans, tasks and work items keep an activity log of every change and comment instead of versions. See Plans and tasks and the work register. Database rows keep their own history; see Databases.
