What is B12?

B12 is an AI builder that manages full website creation, from websites and online stores to web apps, from a short description. You describe your business, and B12 returns a working first draft in about two minutes, already stocked with real content aligned with your industry.

From there, built-in AI tools keep helping you build: new pages, a booking form, a client login, whatever comes next. Over 4 million sites have been built on B12 so far, each with essential tools like payments, scheduling, and SEO baked in.

How is B12 different from Squarespace?

Squarespace leads as a design platform. Its Fluid Engine editor and modern templates produce good-looking sites, especially for portfolios, photographers, and content-driven brands. But business tools a service company relies on live outside the core site plan. Email Campaigns is billed separately, scheduling runs through Acuity, which is sold as its own subscription even if it’s owned by Squarespace, and there's no native eSignature capture.

B12 takes the opposite approach. Describe your business once, and payments, scheduling, contact management, and contracts with eSignatures come bundled from the start. Blueprint AI, Squarespace's tool, is a guided Q&A wizard that picks a layout, palette, and brand personality from preset options with less creative control. B12 generates a custom draft from your description and, on request, wires real backend features into it: accounts, a database, payments, bookings.

Is B12 good for professional businesses?

Yes. B12 is built for consultants, coaches, lawyers, insurance brokers, and other small business owners who need to get paid, book appointments, and manage contracts online. It’s also an ideal platform for founders and creators who want to build their online presence.

Squarespace's strengths (blogging, visual storytelling, product ecommerce) are real, but they're aimed more at creatives and product sellers than at service providers running client relationships through their site.

What can you build with B12?

With B12, you can spin up a marketing site, booking page, online store, or client portal with logins. You can also include contracts, invoicing, email marketing tools, and contact management in one dashboard for a full website creation process.

Squarespace gives you strong design and blogging. But the business layer, such as a real CRM, native eSignatures, and bundled scheduling, isn't part of the core product the way it is with B12.

Does Squarespace include client tools like payments and scheduling?

Partially. Payments and ecommerce tools are native through Squarespace Payments on every tier, from the basic plan up, with advanced ecommerce features stepping in on premium plans. But the Contacts Panel is a basic list, rather than a real CRM. Also, marketing features like Email Campaigns cost extra on top of your site plan, and Acuity Scheduling is billed separately at $20 per month.

Squarespace's plans have crept up over the years too. Once you stack those extras on top, a full client toolkit costs more (and has a time-intensive setup process) than the sticker price suggests, making alternatives more attractive.

When should you pick B12 over Squarespace?

Pick B12 if you’re a founder or creator and run a business and want payments, scheduling, contracts, and client management wired in from day one. It’s also a strong choice if you don’t want to bolt on Acuity, an email tool, and an eSignature app.

Choose Squarespace if design polish, creative freedom, and extensive customization options are your top priority. It’s a solid option if you're selling physical or digital products, or building a portfolio, blog pages, or content-first brand where template quality is the main draw.
