AltText.ai is an AI-powered tool that automatically generates descriptive alt text for images to improve web accessibility and SEO. It helps website owners, ecommerce teams, agencies, and developers make their images visible to AI systems like ChatGPT, Claude, and Perplexity, which rely on alt text rather than pixel data.
The tool integrates natively with major content management systems (WordPress, Contentful, DatoCMS, Storyblok), ecommerce platforms (Shopify, WooCommerce, BigCommerce, Ecwid, Magento), media services (Cloudinary, Dropbox, Pinterest), and browser extensions (Chrome, Firefox). It also offers a REST API, MCP server, and no-code connectors via Zapier, Pabbly, Albato, and SureTriggers.
