# Version

Version lets you save, restore, and compare the analysis state of a notebook. Select **Version** from the menu on the right side of [the header](../../guide/screen-layout) in the notebook screen to show it in the right sidebar.

Parameter values and run results within a version are specific to each user and aren't synced to other users. Parameter changes can also be synced to the URL (see [Specifying values from a URL](./parameter/url)).

## Kinds of versions {#kinds}

| Kind {.nowrap} | Description |
| --- | --- |
| **Manual** | Created manually by a user. Never overwritten automatically. |
| **Automatic** | Created automatically when changes are made. Not created more often than roughly once per hour. Older automatic versions are deleted. |
| **Published** | Created when publishing a report, signed embed, or similar. |
| **AI edit** | Created automatically before edits made by, for example, Agent mode in the [AI agent](../ai-agent/overview#operation-modes) (used for rollback). |

## Operations {#operations}
