Our verdict on B12
B12 is a web-based AI builder for websites, online stores, portfolios, blogs and web apps. You describe what you need, B12 drafts a complete first version in about two minutes, and you keep editing by chatting with its AI agent, to update copy, swap images, add pages or rework the design, or by clicking any element in the visual editor. B12 says more than 4 million sites have been built with it.
Beyond the builder, B12 adds lead-capture and client intake forms, a contact manager, email marketing and automation, commerce, contracts with eSignatures and a client portal. Sites are structured for search from day one, with clean metadata and fast-loading pages, and built-in analytics show what is working. B12 also offers vetted designers, copywriters and SEO specialists through its Expert Marketplace, and its Customer Success team answers by live chat, email or a scheduled call.
The Free plan publishes on a b12sites.com subdomain and includes a mobile-responsive site, store, portfolio, blog or app, five daily AI credits (up to 30 a month), the visual editor with AI chat and team invitations. Website costs $24 a month and adds a custom domain (free for the first year), 100 AI credits a month, up to 10 launched projects, ad removal, commerce, backends, integrations and traffic analytics, with email and chat support. Website + Client Engagement costs $78 a month and adds 300 AI credits, up to 30 launched projects, a custom email address, client intake, email marketing, a contact manager, contracts with eSignature and file uploads. New users pay $1 for the first 7 days.
B12 suits small businesses that want a site, store or simple web app drafted by AI and refined without code, with lead capture and client tools in the same account. Teams that need a dedicated booking system or fine control over pages and code should check those details with B12 first, as its pricing page does not list them.
