What happened to Section Library?

Section Library is now Mason. It's the same app from the same team, repositioned as an AI page builder: on top of the section library, Mason generates full pages and custom sections from a prompt.

Does Mason replace my Shopify theme?

No. Mason installs native sections and templates into the theme you already use, and you edit them in the Shopify theme editor.

How does Mason match my brand?

Mason detects a brand kit from your theme, including colors, fonts and store description, and applies it to every page and section it generates.

Can I preview a page before it goes live?

Yes. Mason can install a generated page as a new template on a draft theme, so you can review it before publishing.

Will Mason slow down my store?

No. Sections are written as lightweight native theme code, with no page-builder runtime or leftover scripts.

Is there a free plan?

Yes. The free plan includes 8 AI credits per month, free sections and basic AI generation. Paid plans start at $9/month with more credits and every section unlocked.

About Mason

What is Mason?

Mason is an AI page builder for Shopify. Describe a landing page, a product page or a single section in plain words, and Mason generates the layout using a brand kit it detects from your theme. Everything installs as native theme sections, so you keep editing in the Shopify theme editor you already know, with no code and no page-builder bloat. New pages can be installed as templates on a draft theme to preview safely before going live, and a library of 200+ ready-made sections is there when you'd rather start from a proven layout.
