Visual Editor: Edit Live Experiments and Attach Images
September 18, 2026
What
The Visual Editor now supports writing changes to a running experiment without stopping it, and attaching images to AI-assisted edits to give the AI visual context when generating element changes.
Why
Users can now update a live experiment's visual changes without stopping and restarting it. Image uploads create much more successful results from the visual editor.
How
Edit live experiments
- Open the Visual Editor on a running experiment. The side panel opens read-only and shows that the experiment is live.
- Choose Edit anyway and confirm. Anything you save goes live immediately to visitors in that variation, with no review step.
Attach images
- In the Visual Editor, click the attachment icon next to the chat input. Attach up to 2 images.
- Type your prompt.
- The image is sent with every step in the tool loop, so the model maintains visual context across multi-step edits.
