Review & Undo

Before it writes anything, MuRu AI saves the page's current content, CSS and metadata to SP Page Builder's own Version History. The snapshot is named “Before AI generation”.

To undo a generation: open SP Page Builder's Version History and restore that snapshot — exactly as you would with any other page change. Any outdated cached styling for the page is also cleared automatically so the new layout displays correctly right away.

If the model's response genuinely cannot be turned into a usable page, nothing is written at all and the window shows why — you never get a half-finished page.
