The problem
Every product image on a Shopify store needs accurate alt text: screen readers depend on it, and search engines use it to understand the page. For a brand with thousands of SKUs, writing it by hand is an operational burden. The engagement that started this build had 7,000 product images to describe.
The tools available at the time produced generic descriptions like “a gold ring on a white background.” They ignored the product title, materials and brand language that drive search performance and real accessibility.
What we built
Caseo.ai combines image recognition with product data. It cross-references the title, description, attributes and collection to write alt text that is accurate, on-brand and optimized for search.
- Azure image recognition for visual analysis.
- OpenAI to add product context, brand tone and SEO structure.
- Native Shopify integration that applies alt text in bulk, with no exports or copy-paste.
- Later expanded to meta descriptions, SEO titles and product page content.
It began as a custom build for one client. We saw the wider need, packaged it as a Shopify app, and it became one of the first AI alt text tools built specifically for eCommerce.
