Midjourney prompt builder

Say what you want to see and tap three options. Our AI writes a full Midjourney prompt, with --ar and --s already at the end.

Free tool · Updated

Style
Aspect ratio (--ar)
How artistic (--s)
Low sticks closely to your words. High lets Midjourney add its own taste.
Describe what you want first, then tap Make my prompt.

How to use it

  1. Write the subject, most important thing first, like “a lighthouse on a cliff during a storm”.
  2. Tap a style and an aspect ratio.
  3. Choose how artistic it should be. Leave it on Default if you're unsure.
  4. Tap Make my prompt, log in with one click, and paste the prompt into Midjourney.

Tips

  • Parameters always go at the end of a Midjourney prompt. The prompt you get is already laid out that way.
  • Raise --s for more artistic results, lower it to follow your words more closely.
  • Add --c 20 or so yourself when you want four quite different options to choose from.
  • Add --style raw for realistic photos. It tones down Midjourney's default polish.

Frequently asked questions

Is this Midjourney prompt builder free?

Yes. A free PromptItIn account writes the prompt, no card needed. You still need your own Midjourney plan to make the images.

What do --ar and --s mean?

--ar sets the aspect ratio, like 16:9. --s (stylize) controls how much Midjourney's own style is applied, from 0 to 1000, with 100 as the default.

Why do I need to log in?

The prompt is written by a real AI model, not stitched together from your picks. The free account covers that and keeps your prompts for next time.

Can I use these prompts in other image tools?

The words before the flags work anywhere, but the flags are Midjourney only. For ChatGPT, Gemini or Stable Diffusion, use the AI image prompt builder.
