Altagonist is a WordPress plugin for generating alt text from image metadata and page content. It can handle hundreds of images in one batch and supports 70 languages. Choose Lite to use image metadata, Medium to add page excerpts, or High to include the full page content. Each image uses 1, 2, or 3 credits, respectively. You can also turn on automatic generation for uploaded images and set a default language and quality level. JPEG, PNG, GIF, and WebP images are supported natively; SVG, AVIF, TIFF, and BMP files are converted automatically. Generated text can be edited in the WordPress media library. All plans support multiple WordPress sites, with credits shared between sites using the same license key. The documentation says images are processed in real time and immediately discarded, and that alt tags are generated in the WordPress admin without adding code or scripts to public pages. The Free plan is 0.00 USD per free and includes 50 monthly credits, up to 50 alt tags, all 70 languages, and every quality tier. Personal, Pro, and Agency are marked Coming Soon.
