AI Featured image for WordPress Plugin Directory

AI Featured Image Generator creates AI-powered featured images right from the WordPress editor. Click “Generate Featured Image” on any post and the plugin builds a unique image from your post title, chosen style, and optional custom prompt, using OpenAI, Stability AI, or Grok/xAI on the free plan, or Google Gemini on Pro.

Every image gets alt text automatically and an SEO-friendly filename based on your post title. Generate one at a time in the editor, in bulk, straight from the Posts list, or inline in your content with the AI Image Generator block. Everything is managed from one settings hub.
