In their own words
CatalogFix
CatalogFix is a web app for improving Shopify product catalog content. It scans active products visible to a store, identifies missing descriptions, weak SEO content, and blank image alt text, then assigns a catalog health score out of 100. Its AI generates product descriptions from each item’s images, title, and existing data, plus SEO meta fields, tags, and image alt text. CatalogFix says meta titles stay below 60 characters and meta descriptions below 155 characters. Product photos are sent to Claude’s vision AI for alt-text generation. Users can review and edit fields, select what to publish, and approve updates to Shopify. A snapshot is saved before publishing, allowing one-click reversion. The app runs in Shopify Admin, uses the Shopify API, and works with any Shopify theme. Free accounts include unlimited previews and a full scan; publishing requires a paid plan. Starter costs $13.99 a month for 50 products monthly; Growth costs $39.99 a month for 300.
