Version History

Voiceblox keeps up to 50 snapshots of your flow in memory. Each significant change (node addition, deletion, parameter edit, edge change) creates a new snapshot.

Version snapshots

When the AI generator applies operations to your flow, it creates a named snapshot with the description of the change (e.g., “Added billing branch”). You can view and restore named snapshots from the Version History panel in the toolbar.
