Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 9 of the 30 other website and landing page builders we grade
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.
To get you started, here are 9 things to know about B12, taken from its own pages and our grades.
A first draft takes minutes and you edit by describing changes, which suits people who hate dragging boxes.
- 1
Best for service firms that want client tools beside the site
The pricier plans add what service firms need: client intake, invoices and eSignatures.
- 2
Paid plans start at $20 a month
As its pricing page puts it: $20 per month, billed yearly ($24 billed monthly).
- 3
There is a free plan
a site, store, portfolio, blog or app on a b12sites.com subdomain, with the visual editor and AI chat, 5 AI credits a day (30 a month at most) and team invites.
- 4
It runs on Web
Web.
- 5
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.
- 6
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.
- 7
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.
- 8
A 2.2 GPA, above 9 of 30
That is against the other website and landing page builders we grade, on value, the free plan, features, ease of use and platforms.
- 9
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.

The report card
Best for service firms that want client tools beside the site
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.
| Subject | Grade | Comment |
|---|---|---|
| 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. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who B12 is for
- Great if you'd rather describe a change than drag things around
- Handy when you run a service firm and want intake forms and invoices beside the site
- Good for owners who'd pay to have B12's own team build the whole site
Who it is not for
- Tight if you tweak a lot, as edits use AI credits and Website has 100 a month
- Pricey if you want client intake or email marketing, at $67 a month
- Skip it if you like placing every element by hand, since edits mostly go through the AI
Good to know
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.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
What you could make
- Templates, forms and invoicing: an app builder makes these well.
What you could not
- A builder that other people can use without writing code.
- A tool that builds and hosts other apps.
- Newsletters sent to thousands of people that still reach the inbox.
- It plugs into other products, Calendly, Ecwid and Eventbrite among them.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. B12’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
