Version History
Snapshots and version history in the Dock Editor. Review earlier versions, restore a previous draft, and see whether a change came from you or from an AI agent.
Version history keeps earlier states of your document so a draft is never a one-way street. You can look back at how the document read at an earlier point, compare it with now, and restore it if you want to go back.
As you work, Dock captures snapshots of the document. A snapshot is the document at a moment in time, a checkpoint you can return to. Together they form a timeline of how the draft evolved, so a major rewrite is recoverable rather than lost.
Open version history to browse the snapshots. Select one to see how the document read at that point. This is useful when you have cut a section you now want back, or when you want to compare a rewritten passage against the version it replaced.
When you find a version you want, restore it to bring the document back to that state. Restoring is itself a change in the timeline, so going back does not erase the versions in between; you can move forward again if you change your mind.
Version history records where a change came from, so a snapshot tells you whether the writing at that point was yours or was produced by an AI agent working on the document. That distinction matters when you are reviewing a draft that both you and the API have touched. For how the document API makes changes, see the agent API docs.
Track Changes is about reviewing individual edits before they commit. Version history is about the document as a whole over time. Use track changes to approve edits as you write, and version history to step back to an earlier full draft.
