Paid plans start at $20/mo. There's also a free plan.

Paid plans cap AI credits and launched projects; extra recurring credits start at $20 per 100 per month on annual billing. A 7-day trial costs $1 on Website and Website + Client Engagement.

03Which plan should you buy?
| If you are… | Get | Why |
|---|---|---|
| Testing drafts on a subdomain | Free | It includes unlimited draft projects and one hosted subdomain site, but has no listed custom domain and is capped at 30 AI credits monthly. |
| Launching a business website | Website | It includes 100 monthly AI credits, up to 10 launched projects and one custom domain free for the first year. |

04Is B12 worth the money?
B12 is worth considering if you want AI site drafting alongside client-facing tools such as intake, payments, contracts and email marketing. The trade-off is that plans have firm credit and project limits: Website includes 100 credits and 10 launched projects, while Website + Client Engagement includes 300 credits and 30 projects. Credit overage rates are not published, and recurring packs cost extra. Price your likely credit and seat needs before treating the monthly plan rate as the full budget.
B12 pricing FAQ
What is the average cost of a B12 injection?
We can't give a sourced average from B12's software pricing: these plans are for an AI website builder, not injections. Injection costs are outside the vendor's listed prices, so don't use the $20–$399 software plan prices as medical costs.
Can I buy vitamin B12 at CVS?
This page covers B12, the website-building software, and its pricing details don't say whether CVS sells vitamin B12. For store availability or product questions, check with CVS directly; the software's Free and paid plans are unrelated to supplements.
Can I take B12 without a doctor?
B12's pricing page is about website software and doesn't provide medical advice about taking vitamin B12. We can't use its plan details to answer a supplement question; ask a doctor or pharmacist about what is appropriate for you.
How much B12 per month?
For the software, B12 costs $0 on Free, or $20–$399 per month with annual billing across paid plans; monthly billing is $24–$399. If you mean vitamin B12 supplements, this vendor's pricing information doesn't list doses or supplement costs.
