Check one public Shopify page for missing alt attributes
Submit one public page URL to count image elements and flag those without an alt attribute. Results appear here; this tool does not email a saved report.
Your contact email is stored with this check, but no saved report is sent. Public HTML only. For a bounded multi-page report with optional saved delivery, use the free catalog gap report.
Catalog gaps are easier to fix when you can see them
Shopify catalogs change constantly. New product images, copied descriptions, and rushed launches can leave missing alt tags and thin metadata across the storefront.
Lumi gives you a clearer starting point before your team spends hours editing product fields manually:
Lumi helps you identify, improve, and document catalog content gaps in a repeatable Shopify workflow.
Why source-level catalog fixes matter
Overlay widgets do not update product data.
The Widget Trap
Overlay widgets may change the storefront experience, but they do not rewrite product image alt text, SEO titles, meta descriptions, or product descriptions in your Shopify catalog.
- Does not fix source code
- Does not improve catalog metadata
- Adds another storefront dependency
Lumi Native Remediation
Lumi helps update the data at the source by writing reviewed, WCAG-aligned alt text into your Shopify catalog after approval.
- Written to product data
- Source-level catalog updates
- Review before publishing
Alt text workflows that match your plan
Free plan
Create basic product-image alt text drafts, review them, and publish approved updates while working with up to three products at a time.
Growth and above
Use Vision-based alt text with product and image context, larger batch workflows, and review controls before publishing.
Accessibility rules are broader than alt text
ADA, WCAG, and EAA accessibility work can involve your full storefront: navigation, forms, media, checkout, theme code, and product content. Alt text is one high-volume field Lumi can help you improve.
Lumi’s audit and remediation workflow helps your team improve catalog accessibility coverage over time.
