AI Image Prompt Generator

Describe the subject, framing, light, and colors of a scene, then combine them into an image-generation prompt.

The output is a main prompt and negative prompt, not an image.

Decide how the subject should appear

  1. Separate subject from setting

    Describe the main subject and action first, then its surroundings. Choose a style such as photography, watercolor, or product advertising.

  2. Set framing and light

    Enter the viewpoint, lighting, and palette, then select a ratio. For a tall poster, for example, choose 9:16.

  3. Review the exclusions

    Read both the main and negative prompts before copying. Check whether your image service has a separate field for exclusions.

Start with
Subject: a cat reading by a window · style: watercolor · ratio: 9:16 · light: natural morning light
Check the result
The text includes watercolor, a 9:16 ratio, morning light, and a separate negative prompt.

The ratio is a written instruction. Check the actual size settings in your image-generation service too.
