B12 review

B12 targets professional service businesses. You describe what you need in your own words, and B12 builds the whole site in about two minutes, then you refine it by chatting with its AI Agent or clicking elements in the visual editor; upload a logo and photos and the agent designs around them. The free plan runs on a b12sites.com subdomain with 5 daily AI credits, capped at 30 a month. The Website plan costs $24 per month and adds a free custom domain for the first year, 100 AI credits a month, up to 10 launched projects, commerce, analytics and email and chat support. The step up, Website + Client Engagement at $78 per month, brings client intake forms, email marketing, a contact manager, contracts and eSignatures. New users can try paid plans for $1 for seven days. The Website plan costs more than several rivals, so B12 makes most sense for firms that will use its client tools.
