Reverse-engineering a usable prompt from an existing image means describing composition, lighting, and style in the specific vocabulary image models actually respond to — not just a plain description of what's in the photo. This tool analyzes an uploaded image with a self-hosted vision model and returns a prompt written in that generation-ready vocabulary, not sent to any third-party AI company.

How to use it

1
Upload the image you want a prompt for

Works on photos, illustrations, or existing AI-generated images.

2
Review the generated prompt

Covers subject, composition, lighting, and style in generation-ready language.

3
Copy and use with your image model of choice

Written generically enough to adapt across different image models.

Tips for better results

  • Use this on an image close to what you want, not just a rough reference. The output describes the image as closely as it can — starting close to your goal produces a more useful prompt.
  • Edit the generated prompt rather than using it completely unchanged. It's a strong starting point, not a guaranteed exact-match description — small edits usually improve it.
  • Try this on your own past generations to understand what worked. Reverse-engineering a result you liked can reveal which specific words were doing the work.

Example output

“Uploading a moody forest photo returns: dense pine forest shrouded in morning fog, soft diffused light filtering through branches, muted green and gray palette, shallow depth of field, atmospheric and quiet.”

TL;DR

Sometimes the fastest way to describe what you want an AI image generator to make is to point it at a photo that already looks close to right. This tool does that reverse step for you: upload a photo, and it analyzes the actual image — subject, setting, lighting, composition, style — and writes a ready-to-use prompt describing it, the kind you’d paste into Midjourney, DALL-E, or Stable Diffusion to get something similar.

Unlike every other tool on this site, this one isn’t a template filling in blanks around your answers — it genuinely looks at the photo you upload. That also means it works differently under the hood: your photo is analyzed by a vision model we run ourselves, not sent to a third-party AI company’s API. It’s used only to generate the description shown to you, then discarded.

Why this needs a real vision model, not a template

Every other generator on this site works by filling in a structured template from choices you make in a form — that works because you already know what you want and just need it phrased correctly. This tool solves a different problem: turning an arbitrary photo into an accurate description is something no fixed template can do, since every photo is different. There’s no way to fake this with dropdowns and text fields — it genuinely requires a model that can look at the image and describe what’s actually there.

What the note field is for

Left blank, the tool describes the photo as a whole — subject, setting, lighting, composition, and style, all at once. If you only care about one aspect (say, you want the lighting and mood captured but don’t need an exact match on the background), the note field lets you steer the description toward what actually matters to you, rather than getting an equally-weighted description of everything in frame.

Who this is for

Anyone who has a reference photo — their own, a moodboard image, a screenshot — and wants an accurate starting prompt instead of trying to describe it from memory. It’s also useful in reverse: upload an AI-generated image you liked from somewhere else to get a prompt you can adapt and reuse.

Example

Uploading a photo of a lighthouse on a rocky coast at sunset, with the note “focus on the lighting,” might produce:

“A white lighthouse with a red-striped top standing on a rugged, rocky coastline, photographed during golden hour with warm orange and pink light raking across the scene from a low sun angle, long shadows stretching across the rocks, calm ocean in the background reflecting the warm sky, shot from a low angle looking slightly upward at the lighthouse.”

Common mistakes this tool avoids

Asking a model to “describe this image” in plain terms, which returns a caption rather than a generator-ready prompt, and reusing that one description across Midjourney, DALL-E, and Stable Diffusion even though each expects genuinely different syntax.

FAQ

Does this work with any AI image generator?

The prompt it produces is plain text, so it works with any image generator that accepts a text prompt, including Midjourney, DALL-E, and Stable Diffusion.

Is my photo stored anywhere?

No. Your photo is analyzed to generate the description shown to you, then discarded — it isn’t saved on our servers or used for anything else.

Why does it sometimes miss a detail I care about?

Vision models describe what’s most visually prominent by default. Use the note field to point it toward a specific detail you want captured.

Can I upload a screenshot of an AI-generated image instead of a photo?

Yes — this works on any image, including ones you didn’t take yourself, as long as you have the rights to use it.

Why does this take longer than the other tools on the site?

Every other tool runs instantly in your browser. This one genuinely analyzes your photo, which takes a few seconds.
