How to Write an Image Prompt Without Creating an Image

By Tools Star Hub Editorial Team · Published

Build prompt writes an image prompt and a negative prompt in the browser. It needs a subject. Generate with AI posts the description to this site, which sends it to Google's Gemini API and returns a longer prompt. This page does not render an image either way. A style preset only fills boxes.

Build prompt turns each filled field into a short clause and leaves empty fields out. Generate with AI sends subject, environment, style, composition, lighting, camera, colors, aspect ratio, mood, quality, and the negative prompt. The request is rejected when subject, environment, and style are all blank, even if lighting or a negative prompt is filled. The AI input can be up to 2,000 characters. Copy prompt and Copy negative prompt copy the local boxes. Copy AI prompt copies the Gemini text.

How to write an image prompt

  1. Describe the subject for the local button. Add setting, light, camera, colors, mood, and aspect ratio when you care about them.
  2. Fill the negative prompt. Put things that should stay out of the frame there. A preset only fills boxes.
  3. Press Build prompt to assemble the text here. Empty fields are left out. The page does not create an image file.
  4. Press Generate with AI when you want Gemini to expand it. Subject, environment, or style has to contain text. The result is still words. Paste them into an image tool if you want a picture.

Example

A studio mug

Subject a mug, style Studio, aspect ratio 1:1, and negative prompt logos becomes Subject: a mug. Style: Studio. Aspect ratio: 1:1. The negative prompt is logos. That Build prompt result stays in the browser. Generate with AI on the same form would send the mug, the Studio style, the 1:1 ratio, and the logos line.

What does this site keep?

What if only the negative prompt is filled?
