What is B12?

B12 is an AI website builder that turns a written description into a working website, online store or small web app. You explain what you need in plain language, the B12 AI agent produces a first draft in roughly two minutes, and you keep refining it through chat or a visual editor until it is ready to publish.

The platform is aimed at small businesses, freelancers, consultants and service providers who want a professional online presence without hiring a developer. Beyond the site itself, B12 bundles business tools such as payments, client intake, contracts and email marketing, so a solo professional can run much of their client workflow from one account.

Key Features of B12

Prompt-to-site generation

You can start from a short sentence or a detailed brief, and B12 generates layout, copy and structure around it. A prompt gallery offers ready examples, such as portfolios, interior design studios or subscription box shops, that you can remix.

AI agent editing

After the first draft, you ask the agent to add a hero section, rewrite text, add pages or change the design. B12 says you can also upload a screenshot of a layout you like as a reference.

Logins, payments and bookings on request

Functionality such as user logins, online payments and appointment bookings can be added by describing it in chat, and paid plans include backends and commerce for stores and simple web apps.

Skills and scheduled tasks

Once a site is live, you can set up recurring tasks and skills for the agent, so the site keeps getting updates rather than sitting untouched after launch.

Client engagement tools

The higher tier adds client intake forms, a contact manager, email marketing, contracts with eSignature and file uploads, which suits service businesses that sell through their website.

Human help when needed

Customer success support is available by chat, email or scheduled call, and B12 runs a marketplace where you can hire vetted designers, copywriters and SEO specialists. Separate done-for-you packages are also offered for businesses that prefer not to build themselves.

B12 Pricing

B12 has a free tier on a B12 subdomain and two self-serve paid plans. New users can currently try the Website plan for $1 for the first seven days, a promotion shown across the site. Monthly and yearly billing options are offered, and AI usage is metered with credits.

The custom domain is free for the first year only. B12 also lists expert-built "do it for you" plans (Professional and Advanced) with extra support; their prices were not shown in the self-serve plan cards.

Prices checked on October 27, 2026; check the official pricing page for current plans.

Who Should Use B12?

B12 fits people who need a credible website quickly and would rather describe it than design it:

Consultants, coaches and agencies that need a site plus intake forms, contracts and invoicing.
Local service businesses, such as cleaners, contractors or studios, that want bookings and payments.
Small shops testing an online store before moving to a heavier e-commerce platform.
Founders who want a simple web app or landing page to validate an idea.

Is B12 Worth It?

B12 is a sensible option if speed and simplicity matter more than pixel-level control. Generating a usable draft from a prompt and editing it by chat removes much of the effort of traditional builders, and the client engagement tools add real value for service businesses that would otherwise pay for separate CRM, email and eSignature apps.

The trade-offs are the credit limits and pricing. The free plan allows only 5 AI credits per day and keeps you on a b12sites.com subdomain with B12 ads, so it works best as a trial. The $24 Website plan is fair for a single business, but the $78 tier is a noticeable step up, and the free domain only covers the first year. If you need complex custom functionality or full design freedom, a developer-oriented tool may suit you better. For small businesses that want a professional site live in an afternoon, the $1 seven-day trial is a low-risk way to find out. You can start at the official B12 website.
