What it does
The visual editor puts the running web app, the codebase, and a set of direct manipulation tools in one window. You drag rendered elements around the DOM tree to reorder buttons, rotate sections, or try a different grid, then tell the agent to apply it and the agent finds the components and updates the source.
For React applications the sidebar surfaces component props, so you can flip a component between its variants and see each state without writing a story or a test harness. Style controls cover the rest: sliders, live colour pickers wired to your own tokens and design system, and precise controls for grid, flexbox and typography.
Point-and-prompt still works alongside the controls. Click one element and say make this bigger, click another and say turn this red, click a third and ask to swap their order. Those agents run in parallel rather than queueing.
Worth knowing
- Prop inspection depends on a React fiber tree being present, so the sidebar is richest on React apps and thinner elsewhere.
- Changes are previewed live but only become code when the agent applies them, which means an unapplied experiment costs nothing and leaves no diff.
