What AltText.io is

AltText.io generates AI-written alt text and image metadata for accessibility, SEO, and stock photography. It works through the web, an API, and an extension, and its homepage says it supports more than 130 languages. The API can return image titles, descriptions, and alt text; stock mode adds buyer-focused keywords. Its WordPress plugin handles new uploads and can bulk-process existing images, with WordPress 5.0 or later and PHP 7.4 or later required. Listed integrations include WordPress, Contentful, Hygraph, DatoCMS, Shopify, WooCommerce, and Magento. It accepts PNG, JPG, and WebP images up to 10 MB. The free plan includes 25 image credits per month; Silver is $19 a month with 600 credits. Credit use varies by task: one for SEO images, two for stock photos, and three for Getty Images metadata. Monthly credits roll over only while customers remain on the same plan.
