Built by AI, shaped by you
The draft you get back is built around what you described. If you said “online store for handmade ceramics,” that’s what shows up: relevant pages, copy, layout, and features. No generic starter site to completely rebuild.
To edit, chat with the AI Agent the way you’d talk to a designer: “make the hero darker,” “add a pricing page,” “write a launch post about our new collection.” Or open the visual editor and click anything you want to change. Most people end up using both.
