B12 uses AI to draft your site, then humans polish it when you ask. Carcin builds your site in 24 hours and then keeps executing on its own: Google, maps, directories, reviews, and 100+ more channels, without waiting for a request.
B12 pairs AI generation with human refinement. The AI drafts a site, and paid tiers bundle the tools a professional-services firm needs: client intake, scheduling, payments, invoicing, email marketing, and contracts and eSignatures depending on the tier, plus 300 AI messages per month on all paid tiers. On the Professional plan at $199/mo, you can request design and copy updates and humans polish the site, with SEO analytics included. There's even an optional do-it-for-you setup for a one-time $1,999.
For a law office, accounting firm, or consultancy that wants a credible site plus client tools, with humans on call to refine it, B12 is a sensible package.
The difference shows up in month 2 and every month after. With B12, you pick a fixed tier: Free on a b12sites.com subdomain, Basic at $49/mo, Basic + Client Engagement at $78/mo, Professional at $199/mo, or Advanced at $399/mo with 5 team seats and extra seats at $29. The human polish is there when you request it. The asking is your job, and the growth work between requests is too.
Carcin doesn't wait to be asked. After the site goes live, it keeps executing on its own: getting you found on Google, listed in directories, collecting reviews, running the channels that bring customers in. 103 channels, sequenced, executed continuously. And the pricing follows the work: usage-based from $19.99/mo, so you pay for what it actually does instead of a fixed tier.

Carcin is a hire that doesn't wait for instructions. Your site is live in 24 hours, and then the growth work runs continuously: 103 channels, sequenced and executed, usage-based from $19.99/mo. You own everything it builds.
If you want a refined site with humans behind it, B12 delivers that. If you want the growth work happening every month whether or not you remember to ask, that's the job Carcin was built for.
For a one-time design pass, humans on request are great. But growth isn't a one-time pass. It's listings, reviews, search visibility, and content, maintained every month. Work that recurs is exactly what software does better than a request queue, and it's the whole product at Carcin.
Yes. Carcin builds your site around how your firm gets clients: the services you offer, the area you serve, the searches that matter. Then it does the work that makes phones ring: Google, directories, reviews, and 100+ more channels, continuously.
Different models. B12 sells fixed tiers, $49 to $399/mo as of June 2026, with human time built into the higher prices. Carcin is usage-based from $19.99/mo: you pay for the work it actually performs. A quiet month costs less, a heavy build month costs more. You're never paying for a tier you don't use.
