AI Image Alt Text Generator is a free, open-source WordPress plugin for generating image alt text during upload or when requested. It can create text for multiple images at once in the media library and gallery block, and provides a manual generation control in the image block and media library. Automatic generation during upload can be configured. It works with OpenAI, Google Gemini, Anthropic Claude, and other providers configured through the WordPress AI Client; at least one provider must be set up before use. Images are sent to the configured provider’s API, so its terms and privacy policy are relevant. Built-in Polylang support detects the language of an image or its parent post. The plugin also exposes an alt-text generation ability through the WordPress Abilities API. Installation involves uploading and activating it in WordPress, then configuring a provider. The directory listing requires WordPress 7.0 or higher and PHP 8.1 or higher. The plugin is licensed under GPLv3 or later, with support through the WordPress.org forum and community development.
