Missing alt text is not just a small metadata issue
Every product image without useful alt text creates friction. Screen reader users get less context. Search engines get weaker image signals. Your team gets stuck fixing repetitive catalog issues by hand.
Lumi helps Shopify merchants replace blank, generic, or keyword-stuffed alt text with clear, product-aware descriptions — without managing spreadsheets or writing thousands of image tags manually.
Support accessibility
Create descriptive alt text that helps communicate what meaningful product images show.
Improve image SEO
Help search engines understand your product images with natural descriptions — not repeated keywords.
Clean up your catalog
Find images without alt text, review suggested descriptions, and save approved updates to Shopify.
From missing alt text to reviewed catalog updates
Lumi helps teams move from discovery to approved fixes with a workflow designed for real Shopify catalogs.
1. Connect your Shopify store
Lumi reviews your product catalog and identifies product images that are missing alt text.
2. Create alt text from each image
Lumi looks at the image and its product details so the suggestion fits the item, variant, and page.
3. Review before publishing
Review, edit, regenerate when available, publish, or leave suggestions unpublished.
4. Update several products at once
Publish reviewed alt text directly to Shopify and keep a dedicated record of completed alt-text fixes.
Turn weak image metadata into useful product descriptions
Lumi keeps alt text descriptive and readable. The goal is to explain the image clearly, not overload it with keywords.

Suggestions based on the actual image
Lumi looks at the product image instead of relying only on titles or tags. That helps reduce generic suggestions and creates more useful descriptions.
Uses your product details
Use product names, variants, collections, and context to generate alt text that fits the page where the image appears.
Update many product images
Clean up missing alt text across many products without writing every tag manually.
Review and edit controls
Every generated suggestion can be reviewed before publishing, so your team can maintain accuracy and brand standards.
Alt text guided by accessibility standards
Create descriptions using Web Content Accessibility Guidelines (WCAG) as a reference. Alt text is one part of accessibility; your theme, navigation, forms, media, and checkout also matter.
Image SEO without keyword stuffing
Create clear image metadata that supports search visibility while staying readable and useful.
Records your team can download
Track completed alt-text fixes and download a CSV record on eligible paid plans.
Future drafts in a supported language
On eligible plans, choose one of 17 languages for future drafts. This is not a Shopify Markets translation workflow.
Accessibility support without empty promises
Alt text alone does not make a Shopify store fully accessible. Accessibility depends on your full site experience, theme, content, navigation, forms, media, and checkout flow.
Lumi focuses on one high-volume accessibility gap: product image alt text. It helps you find missing alt text, create clear suggestions, review them before publishing, and document completed updates.
Improve image SEO with descriptive product alt text
Search engines use image context to understand what a page contains. Product images with clear alt text, relevant page copy, and accurate metadata are easier to interpret than images with blank or generic descriptions.
Lumi helps Shopify merchants create natural alt text that describes the image, supports the product page, and avoids the keyword-stuffing patterns that can hurt quality.
Better product image context
Give search systems clearer information about what each product image shows.
Stronger product pages
Pair alt text with search titles, meta descriptions, and product copy so each product page is easier to understand.
Cleaner catalog operations
Keep product-image descriptions up to date as your catalog grows.
Designed for stores with too many images to fix by hand
Stores with large product catalogs
Fix missing alt text across hundreds or thousands of product images without adding manual catalog work.
Apparel, beauty, home, and visual brands
Create useful descriptions for image-heavy catalogs where product appearance matters.
SEO and ecommerce teams
Improve image metadata while also working on product descriptions, titles, and meta descriptions.
Agencies and consultants
Use Lumi to find missing alt text, review selected drafts with clients, and document completed alt-text fixes. Each client store needs its own Lumi installation and plan.
