What AI Image Alt Text Generator is
AI Image Alt Text Generator is an open-source WordPress plugin that creates descriptive image alt text during upload or on demand. It can process multiple images 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. The plugin uses OpenAI, Google Gemini, Anthropic Claude, or other providers set up through the WordPress AI Client; at least one provider must be configured before use. Images are sent to that provider’s API, so its terms and privacy policy are relevant. The plugin also includes Polylang support to detect an image’s language or that of its parent post, and exposes a generation ability through the WordPress Abilities API. Installation involves uploading and activating the plugin, then configuring a provider. The listing requires WordPress 7.0 or higher and PHP 8.1 or higher. The plugin is free under GPLv3 or later, but AI providers may charge for API requests.
