From prompt to live site in about two minutes

Tell B12 what you want. The AI builds the first draft. You refine it by chatting with the AI Agent or by clicking around the visual editor, then publish when you're ready.

Launch in three steps

1

Describe

A few sentences works: "an online plant store," "a portfolio for my photography," "a habit tracker app," "a website for my accounting practice." But the more specific you are, the more unique the result.
2

Generate

Two minutes later, you have a complete first draft: pages, copy, layout, images, navigation, and built-in features like commerce, forms, and email marketing where they fit.
3

Edit and publish

Chat with the AI Agent to update copy, swap images, add pages, or change the brand feel. Or open the visual editor and click any element to update it. Publish when it’s ready, on a B12 subdomain or your own domain.

All by just briefly prompting AI.

Two ways to edit, side by side

  1. Chat with the AI Agent for the big stuff: "add a testimonials section," "rewrite the about page in a friendlier tone," "make this look more like a fashion brand and less like a corporate site."

  2. Click directly on elements for the small stuff: a heading, an image, formatting, a button color, or margins and spacing.

Most people end up using both.
