AI website builder for sites, stores, and web apps

An AI website builder turns a plain description into a working website. With B12, you describe what you want and get a complete site. Then you shape it by chatting with the AI Agent, in the visual editor or in code. Running a small business? See our guide to the best AI website builder for small business.

Yes. B12 builds a complete, publishable site from your description, including stores and web apps with logins and payments. Treat it as a strong first draft: you’ll still want to add your own photos, details and opinions to make it yours.

B12 builds a complete site in about two minutes. Quicker if you start by remixing one of our templates. From there, refine it by chatting with the AI Agent or in the visual editor, and publish whenever you’re ready.

Yes. On B12’s free plan you can generate a site, edit it with AI, and publish it on a b12sites.com address, with 5 AI credits a day (up to 30 a month). You only pay when you want your own domain, more AI credits, or features like Commerce. Backends are included on the free plan too.

B12 is free to start. The Website plan is $24 a month and includes your own domain (free for the first year) and 100 AI credits a month. Website + Client Engagement is $78 a month and adds client intake, email marketing, contracts, and eSignatures. New users can try either paid plan for $1 for the first 7 days. See the pricing page for everything included.

Yes to both. Hosting and a security certificate (HTTPS) come with every plan, including free, and every B12 site works on phones, tablets, and computers. Paid plans add your own domain.

As much as you like. Ask the AI Agent for changes in plain words, click any element in the visual editor to change it yourself, or edit the code. You can also upload a screenshot, your logo, photos, or your own fonts so the design matches what you have in mind.

B12 sites are set up for search engines from the start, and the AI Agent keeps helping after launch. Ask for SEO research and it pulls Semrush data on search volume, difficulty, and your Google rankings, then plans content around your keywords. You can also run an SEO audit anytime or schedule one every week. Rankings take time and need a launched site on your own domain, and SEO research uses AI credits.

That comes down to what you’re building. B12 is a good fit if you want a site, store or web app that keeps getting better after launch. You can add logins, payments, and bookings just by asking, and the AI Agent researches keywords, reports on your traffic, and runs scheduled checks for you. For a side-by-side look at the main options, see our comparison of the best AI website builders.

ChatGPT can write website code, but you’d still need to host it, connect a domain, and set up forms or payments yourself. An AI website builder like B12 handles all of that and gives you a live site you can keep editing. You can also start a B12 site from ChatGPT with our Website Generator GPT.

It’s built to be. You describe what you want in your own words, no design or coding skills needed, and edit by talking to the AI Agent or clicking on the page. If you’d rather not do it yourself, a B12 expert can help.

B12 builds online stores with a working cart and checkout, and web apps with logins, user accounts, and databases, alongside regular websites. See the AI app builder for more on apps.

B12 builds web apps that work on phones, tablets, and computers. It doesn’t publish native apps to the App Store or Google Play. If that’s what you need, see our no-code app builder page for what B12 can and can’t do.

Yes. Paid plans include one free custom domain for your first year (subject to availability). Search for one and buy it right from your B12 account, and it connects to your site for you. If you already own a domain, or buy one from another registrar, you can connect that instead. On the free plan, your site lives at a b12sites.com address until you upgrade.

AI gets you a working site fast, and you make it yours. Stock and AI images look good but aren’t unique to you, so swap in your own photos and details. B12 builds web apps that run on phones and computers, and it doesn’t publish native iPhone or Android apps. Bigger jobs use AI credits, so heavy editing on the free plan can hit the daily limit.

Yes. B12’s Customer Success team is there by live chat and email. For hands-on work, bring in a B12-vetted designer, copywriter, or SEO specialist through the Expert Marketplace.
