# B12

> AI website builder with client intake, invoicing and email tools

B12 generates a website, store or simple web app from a prompt in about two minutes and lets you change it by telling its AI Agent what to edit or by clicking elements in a visual editor. It is aimed at professional service firms: higher plans add client intake forms, invoicing and payments, email marketing, a contact manager, and contracts with eSignatures. Two further plans have B12's own team design, write and launch the site.

## Ways to pay less

- **Save about 15% with yearly billing** (Annual discount): Yearly billing lowers Website from $24 to $20 a month, Website + Client Engagement from $78 to $67, Professional from $199 to $169 and Advanced from $399 to $339. Source: https://www.b12.io/pricing/
- **First 7 days for $1** (Other savings): A limited-time offer on the pricing page lets new B12 users try the Website or Website + Client Engagement plan for $1 for the first 7 days. No end date is given. Source: https://www.b12.io/pricing/

## Key features

- **AI site and app generation:** A prompt, or a screenshot of what you want, produces a full first draft of a website, store, portfolio, blog or web app in about two minutes.
- **AI Agent and visual editor:** Changes are made by describing them to the AI Agent, or by clicking an element in visual editing mode and asking for an edit. Edits use monthly AI credits.
- **Client intake and contacts:** Intake forms, file uploads and a contact manager collect and organize prospects. They come with Website + Client Engagement and the expert plans.
- **Invoicing, payments and eSignatures:** Higher plans send invoices with automated reminders, take online payments and get contracts signed electronically from the same account.
- **Email marketing:** Email campaigns and automation to existing contacts are included from Website + Client Engagement up.
- **Done-for-you sites:** On Professional and Advanced, a team of copywriters, designers and project managers builds, tests and launches the site, and Advanced adds monthly updates.

## Good for

- Consultants, law firms and other service businesses that want client tools beside the site
- People who would rather describe changes to an AI than drag elements around
- Owners who want experts to build the site for a monthly fee

## Worth knowing

- The free plan runs on a b12sites.com subdomain, shows B12 ads and allows at most 30 AI credits a month.
- Client intake, email marketing, custom email addresses and eSignatures need Website + Client Engagement at $67 a month or more.
- Professional and Advanced carry a setup fee that the pricing page does not price, and they cannot be downgraded to the self-serve plans.
- The included custom domain is free for the first year only.

## ToolGPA grades

**GPA: 2.2 out of 4**, graded Oct 17, 2026. B12 writes you a whole website from a prompt in about two minutes, and you change it by telling its AI what to edit. The pricier plans add what service firms need: client intake, invoices and eSignatures. But edits run on AI credits, and those client tools start at $67 a month.

- **Value for money: C.** Website is $20 a month on yearly billing ($24 monthly), between the middle and the dearer quarter of what builders charge. That gets a custom domain, 100 AI credits a month and no B12 ads. Client intake and email marketing need $67, and the done-for-you plans start at $169 plus a setup fee.
- **Free plan and trial: C.** A free plan with no time limit, but it's on a b12sites.com address, shows B12 ads and allows 5 AI credits a day, 30 a month at most. Since edits use credits, you'll run out fast.
- **Features: C.** A site, store, blog or simple app from a prompt, a visual editor, commerce and analytics, then intake forms, invoicing, payments, email campaigns and eSignatures higher up. Wide, but edits draw on monthly AI credits, and the client tools sit on the $67 plan.
- **Ease of use: C.** No rating on record. A first draft takes minutes and you edit by describing changes, which suits people who hate dragging boxes. But every edit spends a credit, and the client tools need setting up before they earn their keep.
- **Platforms and integrations: B.** A web app with no desktop or phone app listed. It hooks into Calendly, Ecwid, Eventbrite, Disqus, Drift, accessiBe, ConveyThis and Donately.

These are ToolGPA's own grades. Graded from this listing, whose facts were read from B12's own pages on 17 October 2026. Not based on using the product, and shorter than our full reviews.

## Keep it, or make your own?

**Keep it.** To replace B12 you would be making a builder that other people can use without writing code. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 15 of the 30 other website and landing page builders grade higher. It costs $240 a year.

- You could make: Templates, forms and invoicing: an app builder makes these well.
- You could not: A builder that other people can use without writing code.
- You could not: A tool that builds and hosts other apps.
- You could not: Newsletters sent to thousands of people that still reach the inbox.
- You could not: It plugs into other products, Calendly, Ecwid and Eventbrite among them.
- You could not: AI features, unless you pay a model provider for each request yourself.
