Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureAlt Text Pro scans every image in your store (products, collections, blog posts, and files) and shows which are missing alt text. Generate clear, SEO-friendly alt text with AI or smart templates, review it, and save it to Shopify in one click. Run it in bulk or schedule it to run automatically. Title-based templates are unlimited, and AI describes the actual image.
Blank alt text, missing SEO titles, thin descriptions, and uncategorized products make your catalog harder to find and harder to shop, and fixing them one product at a time is slow. Lumi scans your catalog, then drafts fixes from your product photos and details, including a Shopify category with fields like color and material. Good content stays untouched. You approve what goes live, and your theme is never changed.
