Image Describer

Describe any image with AI — detailed descriptions, captions, prompts, and text extraction in one place

Intention-driven descriptions

Pick from templates like detailed, brief, story, fashion, person, caption, or object recognition — or write your own custom intention to steer the output.

Image to AI prompt conversion

Turn any reference image into a ready-to-paste Midjourney, Stable Diffusion, or Flux prompt, so you can recreate a similar theme or style.

AI-powered OCR and text extraction

Pull text out of photos and screenshots with better accuracy than plain OCR, keeping layout and line breaks wherever possible.

Captions, alt text, and marketing copy

Generate social-ready captions with hashtags, accessibility alt text, or product marketing copy from a single product image.
