AltText.ai

AltText.ai generates alt text for images in many languages, for accessibility and image SEO. A free scanner crawls a domain's pages, lists images with missing descriptions and shows which images ChatGPT, Claude and Perplexity cannot see, giving an AI visibility score. Descriptions are written automatically for each new upload and can be applied in bulk to existing media, with options for SEO keywords and a final pass. It plugs into WordPress, Shopify, WooCommerce, BigCommerce, Magento, Webflow, Contentful, DatoCMS, Storyblok, Cloudinary, Dropbox, Google Drive and Pinterest, and offers a developer API, an MCP server, no-code connectors, Google Tag Manager support and a Chrome extension and Firefox add-on for right-click alt text. Storefront integrations add product data to the generated text. A free site scan and a set of free images come with a free account, and no credit card is needed for the trial. One account can cover many client projects for agencies that manage several sites.
