B12.io (b12.io) is an AI-powered website builder and client engagement platform founded in 2015 and headquartered in New York. Unlike general-purpose website builders, B12 is specifically designed for professional service businesses — lawyers, accountants, consultants, therapists, coaches, and agencies — that need not just a website but a full online business presence including client scheduling, online payments, contract signing, email marketing, and intake forms. B12's AI generates a complete, professionally designed website from a business description in seconds, then provides the surrounding business tools as an integrated suite.
B12's AI drafts website copy, selects relevant imagery, organises service pages, and applies a visual brand — creating a working website draft that professionals can refine rather than build from scratch. The platform is also notable for offering optional human expert review: B12's in-house designers and copywriters can review and refine AI-generated websites for an additional service fee, combining AI speed with professional quality assurance for businesses that want both.
How B12.io Works
Users enter their business name, industry, and a brief description. B12's AI generates a complete multi-page website draft within seconds — including homepage, services page, about page, contact page, and any industry-specific pages (e.g. practice areas for law firms, specialisations for consultants). Users review and edit the draft in B12's visual editor, customising text, images, and layout. Business tools — scheduling calendar, payment processor, intake forms, email marketing — are configured and added from the B12 dashboard. The site is published on a custom domain (on paid plans) with automatic SSL and hosting included.

Who Should Use B12.io?
B12.io is best suited to solo professionals, small professional service firms, and consultants who need a complete online business presence — not just a website but also scheduling, payments, and client communication tools — without managing multiple separate software subscriptions. It is particularly strong for lawyers, accountants, therapists, coaches, and freelance consultants who want an all-in-one solution that looks professional from day one. The optional human expert review is a meaningful differentiator for professionals who want AI speed but are not confident editing their own website copy. B12 is less suited to e-commerce businesses, content-heavy sites, large agencies, or users who need deep design customisation beyond its professional service templates.
Frequently Asked Questions
Is B12.io free to use?
Yes. B12.io offers a permanently free plan that includes AI website generation, basic site editing, and limited access to client tools on a B12 subdomain. No credit card is required to sign up and generate the AI website draft. The free plan is suitable for evaluating the AI generation quality and the platform interface before upgrading to a paid plan for custom domain, full client tools, and professional features.
What types of businesses is B12.io designed for?
B12.io is specifically designed for professional service businesses — lawyers, accountants, consultants, therapists, coaches, financial advisors, marketing agencies, and similar knowledge-based service providers. Its templates, AI-generated copy, and built-in client tools (scheduling, payments, intake forms, contracts) are all optimised for service business workflows rather than product retail or content publishing.
How much does B12.io cost?
B12.io's Basic plan costs $49/month ($42/month billed annually) and the Professional plan costs $78/month ($67/month annually). Annual billing saves approximately 14–15%. A permanently free plan is available with no credit card required. The Professional plan's email marketing, contracts, and contact manager make it the most complete option for service businesses replacing multiple separate tools with a single subscription.
Does B12.io include client scheduling and payments?
Yes. B12.io includes a built-in appointment scheduling calendar that allows clients to book consultations and meetings directly from the website, and an online payment feature for accepting fees and sending invoices. Both are included in the Basic paid plan. This makes B12 an all-in-one solution for service professionals who would otherwise need to subscribe separately to tools like Calendly for scheduling and Stripe for payments.
What is B12's human expert review service?
B12.io offers an optional human expert review service where the company's in-house designers and copywriters review and refine the AI-generated website — improving the copy quality, adjusting visual design, and ensuring the site accurately represents the business. This is available as an additional service on top of the subscription and is particularly useful for professionals who are not comfortable editing website copy themselves or who want a higher level of professional polish than they can achieve through self-editing alone.
