Ready for your review

Describe the image in its page context. Decorative images may need empty alt text.

Helpful drafts. Clear boundaries.

Alt text alone cannot make a store accessible. Your theme, navigation, forms, media, and checkout still need a broader review.

Compare plans
  • Content batches you start always create drafts for review. Maintain can generate selected new-product content and missing image alt text after product updates. Enabled Maintain automation can publish automatically. Turn it on only for content you want published without prior review.
  • Free includes 100 monthly credits for product descriptions and alt text. SEO fields and brand guidance require an eligible paid plan.
  • Eligible plans can generate future drafts in one of 17 supported languages. Lumi does not manage Shopify Markets translations.
  • Generation history and completed alt-text fix records are different. CSV exports on paid plans cover completed alt-text fixes. They are records of work through Lumi, not proof of accessibility compliance.

A few goodquestions.

Shopify Alt Text Generator questions, answered.

What is a Shopify alt text generator?

A Shopify alt text generator creates written descriptions for product images. Lumi looks at the image and its product details, suggests a description, and lets you review it before saving it to Shopify.

Can Lumi fix missing alt text in bulk?

Yes. Lumi identifies connected product images with missing alt text, creates drafts for selected images in plan-sized groups, and lets you review updates before publishing them.

Is AI-generated alt text good for SEO?

Descriptive alt text gives search systems useful image context, but it does not guarantee rankings or traffic. Review each Lumi draft for accuracy and avoid keyword stuffing.

Is Lumi a complete ADA or WCAG solution?

No. Alt text alone cannot make a store accessible. Lumi helps create and document product-image descriptions using Web Content Accessibility Guidelines (WCAG) as a reference. Your theme, navigation, forms, media, checkout, and legal context also matter.

Can I review alt text before publishing?

Yes. Lumi gives you review and edit controls before applying generated content to your store.

Does Lumi only generate alt text?

No. Free also includes product-description drafts. Eligible paid plans add SEO titles, SEO descriptions, brand guidance, and one of 17 supported languages for future generation.

Who should use Lumi?

Lumi is best for Shopify merchants, ecommerce teams, and agencies managing image-heavy catalogs, frequent product launches, or large backlogs of missing alt text and product content.

Is there a free plan?

Yes. You can start with 100 free credits and upgrade as your catalog needs grow.
