About AI Image Prompt Builder
The AI Image Prompt Builder assembles a structured prompt for image generators from separate parts: subject, style, lighting, composition and extra details. Working in parts helps you change one aspect of an image at a time and keep results consistent.
How to use it
- Describe the subject, for example "a red fox in a snowy forest".
- Add a style, lighting, composition and any extra details.
- Choose an aspect ratio: 1:1, 16:9, 9:16, 4:3 or 3:2.
- Optionally add a negative prompt, then copy the result into your image tool.
Good to know
- The parts are joined into a single comma-separated prompt, ending with the aspect ratio.
- The negative prompt lists things to avoid, such as "blurry, low quality". Only some image tools accept a separate negative prompt.
- Some tools set the aspect ratio with their own setting or parameter, so check their documentation if the ratio in the text is ignored.
Common questions
Which image generators does this work with?
The output is plain descriptive text, so it can be pasted into most image generators.
Why does changing one word change the whole image?
Image models are sensitive to wording. Changing one part at a time, as this tool encourages, makes it easier to see what each change does.
