AI Alt Text Image Generator

AI ALT Text Image Generator automatically generates descriptive, SEO-friendly, and accessibility-compliant ALT text for your product images using artificial intelligence.
This extension enhances both your store’s search engine optimization and accessibility compliance by leveraging your product information as context to create human-readable and AI-parsable ALT text.

The extension connects to AltReadable.com, a specialized service that generates ALT text designed to be accessible for screen readers and readable by AI tools like ChatGPT, Claude, and Gemini. By adding rich, contextual image descriptions, your store becomes more discoverable and accessible, something key for SEO, WCAG/ADA compliance, and AI-driven product discovery.

You can generate ALT text manually, via background processes to avoid timeouts, or automatically using a cron job for new products making it ideal for stores with large catalogs.
