Image to prompt: get the prompt of an image with AI

An image becomes a detailed prompt and a keyword prompt, in English, then two models run them to check that they reproduce the subject and style. Workflow shown here, no account needed.

Real workflow: a nest of clay chicks becomes a one-paragraph prompt and a keyword list. Seedream 5 Pro and Nano Banana Pro, without seeing the image, turn them into two clay nests: subject and style found again.

You found an image whose style you want, or you want to redo one of your images with another model: you need the prompt. This workflow gives the image to Gemini 3.8 Flash, which describes it as a prompt in two ways: a detailed paragraph and a keyword list.

The hard part is knowing whether the prompt works. Here, the proof is on the canvas: each prompt is sent to an image model that never sees the original. If the render finds the subject and the style, the prompt is good, and you can edit it to change the subject while keeping the style.

To keep the same character from one image to the next, see consistent characters; to write your prompts yourself, the method that works. The full workflow costs twenty-six credits, the two prompts alone two credits.

Who it is for

AI image creators, designers and marketers who want to reproduce a style, redo an image with another model or learn to write their prompts.

Which files to provide

An image you have the right to use, ideally sharp and fairly large.

How it works

  1. 1

    Drop your image

    An image you have the right to use: yours, or a free one. The prompt describes, it does not copy.

  2. 2

    Run the two Text nodes

    Gemini 3.8 Flash reads the image and writes a detailed prompt, then a keyword list, in English.

  3. 3

    Check with an Image node

    Each prompt goes into an image model that never sees the original. Compare: subject, style, light.

  4. 4

    Edit and reuse

    Change the subject in the prompt while keeping the style words, and you get a consistent series.

Variations and use cases

The same canvas, tuned for different needs: each variation is two or three lines of prompt away.

Recover a style for a series

A successful illustration becomes a prompt whose style words you keep, then you change only the subject to get a whole series of consistent images.

Move from one model to another

An image made with an older model becomes a prompt you run on a newer model, to redo it in better quality without starting from scratch.

Learn to write prompts

Comparing the image with the prompt that describes it shows which words carry the light, the material and the framing, and what you usually forget to write.

A brief for a designer or a client

A reference image found on a moodboard becomes precise text to send, saying what you like in the image instead of a simple like this.

Alt text and captions

Once shortened, the detailed prompt also works as an image description for a website's accessibility or as a caption for a post.

Video from an image

The detailed prompt, with a camera move added, goes into a Video node to animate the same scene in the same style.

Common mistakes

Believing in the original prompt

No tool recovers the exact prompt of an image. What you get is a description that works, to be checked with a render.

Forgetting the material

Without the material and rendering (clay, watercolor, film photo), the model keeps the subject but changes the whole style.

Keeping artist names

An artist or artwork name in a prompt raises rights issues and works poorly. The instruction forbids them, keep it that way.

Expecting an identical face

A prompt does not reproduce a specific person. For a face, wire a reference photo to the Image node.

Frequently asked questions

Is it the original prompt?

No, nobody can read the original prompt from an image. It is a description written to reproduce the image, and the Image node checks that it does.

Why a prompt in English?

Every image model understands it best. You can ask for a prompt in another language by changing the Text node's instruction.

Does it work with a photo?

Yes: subject, framing, lens, light and mood are described. A specific face cannot be recovered from a prompt: for a person, you need a reference image.

How much does the workflow cost?

Twenty-six credits: one credit per prompt on Gemini 3.8 Flash, five for the Seedream 5 Pro image, nineteen on Nano Banana Pro. The two prompts alone cost two credits.

Why Gemini 3.8 Flash?

It reads images well, describes material and light precisely, and costs one credit. Claude Sonnet 5.5 does as well on complex scenes, at a higher price.

Can I use the prompt in another tool?

Yes, it is text: copy it from the Text node and paste it anywhere. The keywords suit tools that prefer lists.

Can the prompt be used for a video?

Yes: add a camera move and an action to the detailed paragraph, then wire it to a Video node.

What about other people's images?

Describing an image for inspiration is common; reproducing someone's work to publish it is not. Start from your own images or free ones.
