Alt Text Studio

Alt Text Studio is a WordPress plugin for automatically generating alt text for images on a WordPress site. It is described as making images accessibility-ready and SEO-optimized, and it is built for WordPress workflows with no clicks required for new uploads.

Every new image uploaded to the Media Library gets alt text generated in the background. For existing images, it can bulk generate alt text for hundreds of files at once, with filtering by missing alt text, date, or post type, and the process can be paused and resumed. It also pulls focus keyphrases automatically from Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework, SmartCrawl, and Squirrly. The plugin is WooCommerce-ready, generating product image alt text with the product name, brand, and color attributes. It supports generation in 194 languages, including multiple languages at once, and includes full support for WPML and Polylang with translations that propagate automatically.

The plugin can be automated from the command line with wp alttextstudio generate, and it offers 10+ actions and filters for customization. Additional integrations listed on the site include YITH Brands, Gutenberg, and WP Multisite. It is delivered through WordPress.org, where installation is described as installing and activating the plugin from the WordPress admin. Use also requires pasting an API key from an Alt Text Studio account into the plugin settings and connecting it there.

Alt Text Studio starts with 25 free credits, does not require a credit card, and allows cancellation at any time.
