B12 review

B12 is an AI website builder for businesses that want a site, online store or web app without starting from a blank page. Describe the project, and its AI agent creates a draft. You can then chat with the agent to change the design, rewrite sections or add a backend, and publish the result.

It is more than a page builder: B12 also offers on-page SEO tools and client-work features, including intake forms, contact management, email marketing, commerce and contracts with e-signatures. You can add skills and scheduled tasks, too. That makes B12 worth considering if you want a website alongside basic client operations in one service. It is less compelling if you only need a simple site and would rather pay for a basic builder than a broader set of tools.

B12’s main draw is the short path from a description to an editable draft. The AI agent can revise designs and copy through chat, and the builder supports stores and backends as well as standard business sites. That gives it more room than a tool limited to generating static landing pages.

The client features may also reduce the number of separate services a small business needs. B12 lists intake forms, contact management, email marketing, payments, commerce and contracts with e-signatures. Its plans separate basic website publishing from client engagement, so you can pay for the latter only if those tools fit your workflow.

• The Free plan costs $0 and allows unlimited draft projects, team invitations and one hosted site on a B12 subdomain.
• The Website plan is listed at $24 monthly or $20 per month billed annually. It includes 100 AI credits a month and up to 10 launched projects.
• Website + Client Engagement costs $78 monthly or $67 per month annually, with 300 credits, up to 30 launched projects and client tools.

B12 also lists a seven-day trial for $1 on the Website and Website + Client Engagement plans.

The free plan is for drafting, not a full custom-domain launch: it includes one hosted site on a yourbusiness.b12sites.com subdomain and only five AI credits daily, capped at 30 a month. The Website plan raises that to 100 monthly credits, but limits you to 10 launched projects. Website + Client Engagement allows 30 projects and 300 credits. Those caps matter if you expect to build or revise several sites.

More credits are a recurring cost. B12 lists extra credits at $25 per 100 monthly on monthly billing or $20 per 100 monthly on annual billing, up to 10,000 a month. Extra seat pricing is $29 per seat monthly; the Advanced plan includes five seats. B12 does not publish pay-as-you-go or automatic overage rates, and add-on credits and overages are not published for Free, so upgrading may be necessary.

The higher tiers are a meaningful spend: Professional is $199 monthly or $169 annually, and Advanced is $399 monthly or $339 annually. Both include 300 credits, while their added support and services may be unnecessary if you only want a site.

B12 has a free plan, but launching a site starts at $24 per month, or $20 per month with annual billing, according to the pricing details checked November 7, 2026. Free is for drafts: it includes one hosted site on a B12 subdomain and 5 daily AI credits, capped at 30 per month.

Website includes 100 monthly AI credits and up to 10 launched projects. Moving to Website + Client Engagement costs $78 monthly or $67 monthly on annual billing; it raises the limits to 300 credits and 30 projects, and adds client tools. Professional is $199 monthly or $169 annually, while Advanced is $399 or $339. Both include 300 credits, so the higher price buys support or team features, not more included AI usage.

The listed $1, seven-day trial applies to Website and Website + Client Engagement. Extra credits cost $25 per 100 monthly, or $20 per 100 with annual billing, up to 10,000 credits monthly. Automatic overage rates are not published. Extra seats are $29 per month; Professional and Advanced setup costs $1,999.

Moving to B12 means starting with an AI-generated draft from a description, then editing it with the AI agent and setting up the site and any client tools you need. The published product details do not describe importing an existing site, so treat a rebuild or manual content transfer as a possibility—not a confirmed requirement. Paid Website plans include one custom domain free for the first year; check what happens to the domain and site hosting before you commit.

For a move away, the available information does not say whether B12 exports site files, content, contacts, contracts, or other data. Confirm export options and ownership of your domain before relying on B12 for business-critical records. The published published material contains no Reddit posts or comments about why users leave B12, so we can’t substantiate a Reddit-based account of switching problems. In short: migration effort, export support, and lock-in details are not published here; ask B12 directly before moving an established site.
