B12 pairs an AI-drafted site with human experts and client tools for professional services. Free, Website $24/mo, Website + Client Engagement $78/mo. Honest September 2026 review and alternatives.
B12 is a good AI website builder for professional service firms that also want client intake, scheduling and payments in one place, with real people available to help. As of September 2026 it has a Free plan, Website at $24 a month, and Website + Client Engagement at $78 a month. If you only need a website, that top tier is expensive, and there are cheaper ways to get an AI-built site.
Start free with a template site; AI builds from one prompt on paid plans from $20/mo. On Starter you can compare B12's draft with a We.Inc one-prompt site.
B12 (b12.io) is a website platform built for professional services: accountants, law firms, consultants, coaches, therapists and similar businesses. You give it information about your firm, its AI generates a draft site, and you can edit it yourself or lean on B12's experts. Around the site it adds client-facing tools: online scheduling, intake forms, payments and invoicing, and email marketing.
The pitch is less "build a site in a minute" and more "run the client side of a service firm with a site attached."

B12 sites include the standard settings: titles, descriptions and mobile layouts, and its page structures suit professional services. As with any AI draft, rankings come from specific, trustworthy pages: one per service, clear credentials, named team members and location details. Service firms that add those details usually do better than firms that publish the draft as it is, whichever builder they use.
B12 is a thoughtful product for one audience: professional service firms that want a credible site and client tools under one roof, with help on hand. For them, the $78 plan can replace several subscriptions. For everyone else, and for firms that only need the website, $24 a month or less gets you an AI-built site elsewhere.
