What is B12

B12 is an AI powered website builder that turns a short text prompt into a complete website in a few minutes. You describe your business or idea, and the AI creates the pages, layout, copy, images, and structure for you.

Once the first draft is ready, you can keep improving it by chatting with the AI Agent, clicking and editing parts of the page directly, or working with the code if you want more control.

B12 also comes with built in business tools such as online payments, invoicing, email marketing, contact management, and appointment scheduling, so you can run your business from the same place your website lives.

If you would rather not build it yourself, B12 also offers expert designed plans where real people help set up and manage your site.
