## Additional feature information

With the revision history feature, you can:

* Create a named historical version – a revision – of the content by bundling changes together in a save cycle.
* View the chronological history of revisions of your content.
* Restore an earlier revision of your document to reverse any changes.
* Compare selected revisions to each other and view changes between.
* Mark revisions and changes that involved AI, so reviewers can tell them apart from manual edits.

You can also read a dedicated blog post that [compares revision history with the track changes feature](https://ckeditor.com/blog/ckeditor-5-comparing-revision-history-with-track-changes/) and points out similarities and differences between these two features.

## Marking AI changes

When you use CKEditor AI together with revision history, you can mark the revisions and changes that involved AI. To learn how to turn the markers on, refer to the [Marking AI-generated suggestions](../../ai/ckeditor-ai-generated-suggestions.md#marking-ai-changes-in-revision-history) guide.

## Use as a standalone plugin

Revision history does not require real-time collaboration to work. You can add it to CKEditor 5 just like any other plugin.

To learn how to integrate revision history as a standalone plugin, refer to the [Integrating revision history with your application](revision-history-integration.md) guide.

## Use with real-time collaboration

If you are using the real-time collaboration feature, refer to the [Real-time collaboration features integration](../real-time-collaboration/real-time-collaboration-integration.md) guide.
