AltText.io
What it is
AltText.io generates AI alt text and image metadata for accessibility, SEO, and stock photography. It works through the web, an API, and an extension, and the homepage says it can produce alt text in more than 130 languages. The API can return image titles, descriptions, and alt text; stock mode adds buyer-focused keywords. Integrations listed include WordPress, Contentful, Hygraph, DatoCMS, Shopify, WooCommerce, and Magento. Its WordPress plugin processes new uploads and can bulk-process existing images; it requires WordPress 5.0 or later and PHP 7.4 or later. Supported formats are PNG, JPG, and WebP, with a 10 MB maximum image size. Credit use is one for SEO images, two for stock photos, and three for Getty Images metadata. Monthly credits roll over while a customer stays on the same plan; changing plans resets them to the new plan’s monthly amount. The free plan includes 25 image credits per month. Silver costs $19 a month and includes 600 credits. The maker says uploaded images are temporarily stored for processing and deleted after generation.
