About B12

Overview

B12 is an AI website builder that turns a short prompt into a complete website, web app, or online store. The page says more than 4M websites have been created with its builder.

Users can start for free, preview or remix AI-generated projects, and update their site by chatting with AI before they go live.

Key Benefits

  • Generate a complete website, app, or store from a short prompt.
  • Update design, content, and features by chatting with AI.
  • Start from remixable AI-generated templates such as portfolios, online stores, and apps.
  • Reach out to the B12 team for extra help with edits, as customers on the page describe.
  • Start for free, with a limited-time $1 trial for 7 days advertised.

How It Works

Describe your idea with a short prompt about what you want to build. B12 generates a complete website, app, or store around that idea, and you then update the design, content, and features by chatting with AI before you go live.

  • Jewelry sellers launch an online store.
