How to use it

  1. Write the subject in a few words, like “a red fox sleeping in snow”.
  2. Tap a style, mood and aspect ratio. Skip any you don't care about.
  3. Pick where you'll use it, so the prompt is written for that tool.
  4. Tap Make my prompt. Log in with one click and your prompt is written right away.

Tips

  • Be specific about the subject. “A red fox curled up asleep” beats “a fox”.
  • One style is enough. Mixing three styles usually gives a muddy result.
  • Leave options empty if you're unsure. The AI picks lighting and camera to suit the subject.
  • If the image misses, change one thing and make the prompt again so you know what helped.

Frequently asked questions

Is this image prompt builder free?

Yes. Picking options is open to everyone, and a free PromptItIn account writes the prompt. No card needed.

Why do I need to log in?

The prompt is written by a real AI model, not filled into a template. The free account covers that cost and keeps your prompts so you can reuse them.

Which image generators does it work with?

Any that take a text prompt: Midjourney, ChatGPT (GPT image), Gemini, Stable Diffusion, Flux, Ideogram, Leonardo and others. Pick your tool and the prompt is written for it.

What makes a good AI image prompt?

A clear subject, then style, lighting, camera angle and mood, in that order. Short, concrete words work better than long sentences.
