Explore UI drafts, then rebuild your favorite.

What it does

Generate and refine UI drafts, then retrieve a design spec to rebuild the chosen draft in your project's stack.

When to use it

Use when the user wants to sketch new UI, iterate on a generated draft, or retrieve a draft's code.

How to use it

Give it a UI description or a change to an existing draft; it generates or refines variants and brings the chosen design into the project.
