Turn a plain-language idea into a working website or web app
Start from a description, upload images or a brief, menu, or catalog, or paste a Google Maps business link to get an editable site built from existing business details.
Click any section to update copy, layout, spacing, images, or components and see the change immediately without writing code.
Attach payments to purchases, bookings, memberships, and other key flows so a generated site can accept revenue.
Manage pages, products, services, orders, and customer records in one place without editing the website itself.
