Mason vs B12

Mason sells AI software for online stores, centered on the ModeMagic Shopify app and an AI content engine for commerce teams. Merchants use it to run smart carts, lightning deals, price drops, and personalized bundles without stitching together five separate marketing plugins.

Shopify's app store is full of single-purpose widgets. Mason groups revenue, conversion, and content tools under one agentic shopping engine, with a Grow plan at $249 per month for smaller brands and a Scale tier for larger stores that need a dedicated account team. The FAQ still references a $49 entry plan with order caps, so pricing scales with store volume rather than staying flat.

DTC brands, Shopify merchants, and retail marketers use Mason when paid ads are expensive and they want on-site promotions, segmentation, and campaign reporting in one dashboard. Integrations highlighted on the site include Shopify, and the company lists backing from Lightspeed, Accel, and Ideaspring Capital.

B12 turns a short text prompt into a live website, online store, or lightweight web app in about two minutes. Its AI builder drafts mobile-responsive pages, then you refine layout, copy, and features through chat or a visual editor without touching code.

Squarespace and Wix ship template libraries you customize manually. B12 bundles site generation with commerce backends, client intake forms, invoicing, contracts, email marketing, and an expert marketplace when you want humans involved. That makes it closer to an all-in-one stack for service businesses than a pure site builder.

Freelancers, coaches, and small firms use it to launch on a free b12sites.com subdomain or move to a custom domain on paid plans. B12 says more than 4 million sites have been created on the platform, with Website at $49 per month (200 AI credits) and Website + Client Engagement at $78 per month (300 credits), both offered at $1 per month for the first three months for new users.
