What it is
A SaaS tool that generates descriptive alt text for images automatically using a vision-language model, aimed at organizations with large or constantly growing image libraries — e-commerce catalogs, publishers, agencies. It offers a free scanner that audits up to 25 pages of a site for missing alt text, a bulk updater that backfills existing images, native integrations with Shopify, WooCommerce, BigCommerce, Magento, WordPress, Contentful and others, a browser extension, and a REST API/MCP server for custom pipelines. Generation supports over 130 languages.
