B12

What B12 builds

B12 is an AI website builder for creating websites, online stores and web apps from a plain-language description. You explain the business or product, receive an initial structure and content, then refine the result through AI chat or a visual editor.

The current product goes beyond a brochure website: B12 describes apps with logins and databases, as well as commerce and client engagement tools. It suits small businesses, consultants and founders who want a public site and related customer workflows in one service. A portfolio, service business site, store and simple business tool require different inputs, even when they begin in the same builder.

Editing pages and adding business functions

The builder overview describes generating page layouts, copy and images, then changing them through conversation or by selecting elements visually. Screenshot guidance can communicate the look you want. The AI Agent can revise text, adjust styling and add pages as the brief becomes more specific.

B12's backend product covers accounts, databases, file storage, payments and booking flows. The vendor identifies Supabase as underlying infrastructure. These features make a member dashboard or data-backed tracker a different project from a static landing page, with access rules and saved information that need attention.

Client engagement tools include intake forms, contact management, email marketing, contracts and electronic signatures. Their purpose is to carry a visitor from an initial inquiry into an ongoing client relationship. Availability varies by plan, so identify the actual business process before choosing a subscription.

Example: launching a consulting website

A consultant could begin with a prompt describing their services, intended clients, brand tone and required pages. They might ask for a home page, service details, an about page and an inquiry form. After generation, they replace invented examples with real credentials, review the copy and adjust page hierarchy in the editor.

Next, they can add the appropriate intake or booking workflow and check that an inquiry reaches the right person. If a client portal is part of the project, they should define what clients can see and what remains private. Testing with a separate client account is more informative than reviewing only the administrator's preview.

Before publishing, inspect mobile layouts, form confirmations and links. After launch, edit the site as services change rather than relying on the first AI draft to remain accurate. These are practical review steps, not a guarantee that a generated site is ready without further work.

Limits, support and pricing access

AI-generated design and text still need editorial and functional review. A convincing page does not establish correct payment behavior, appropriate data access or accurate business claims. Integrations can require separate accounts and configuration; check the specific service you intend to connect.

B12 offers on-page SEO tools, but publishing a site or filling metadata does not guarantee search rankings. For a complex application, establish requirements, test account roles and decide who will maintain the result.

The pricing page lists free access on a B12 subdomain with limited AI usage and paid options for additional features. Custom domains, backend and client engagement needs affect the choice. Optional expert setup and marketplace work should be evaluated separately from self-service access. The help center provides setup guidance.
