Measures how much useful information your prompt gives the AI. It does not predict or guarantee the quality of any AI’s answer.

How to Use the AI Image Prompt Generator

  1. Describe the image in a sentence, for example “a cozy coffee shop on a rainy evening”.
  2. Choose a style and level of detail, or leave them on automatic.
  3. Generate the prompt and adjust any part of it.
  4. Copy it into your image generator, and add that tool’s own settings, such as aspect ratio, if it has them.

How to get better AI images

  • Be specific about the subject

    “A golden retriever puppy sitting on a red blanket” beats “a dog”. Describe the main subject first, then the setting.

  • Name the style

    Photograph, watercolor, 3D render or flat illustration. The style word changes the result more than almost anything else.

  • Describe the light

    Soft morning light, neon glow, studio lighting. Lighting sets the mood of the whole image.

  • Iterate

    Change one part at a time (the style, then the camera angle) and compare. You learn faster what each word does.
