How it works
Accepted customizations are saved per-hostname and re-applied automatically on future visits. You can view, edit, and delete rules from the extension's settings page.
Click the Folded toolbar button on any page.
Describe the change you want (e.g. "hide the sidebar", "make the font larger", "remove ads").
Folded sends a snapshot of the page's DOM structure to Claude, which returns the CSS and/or JavaScript needed.
Preview the change, then accept or discard it.
