AI Featured Image Generator

AI Featured Image Generator lets you create AI-powered featured images right from the WordPress editor. Hit "Generate Featured Image" on any post, and the plugin uses your chosen AI provider — OpenAI, Stability AI, or Grok/xAI (all free), or Google Gemini (Pro) — to generate a unique image based on your post title, chosen style, and an optional custom prompt. You can also choose whether to allow text on the generated image or keep it text-free.

Every generated image automatically gets alt text set in the WordPress media library — improving SEO and accessibility without any extra work. You can configure the alt text source (post title, prompt, or a custom template with placeholders like {title}, {style}, and {site_name}), or turn it off entirely from the General settings tab.

Free users get a Bulk Generate tab to create featured images for up to 5 posts per batch (50 images lifetime). Pro users unlock unlimited bulk generation, advanced filters, Gemini support, image upscaling, background removal, and an AI Image Generator block for adding inline images directly inside the Gutenberg editor. Everything is managed from one settings hub.
