Midjourney Prompt Builder
Build optimized Midjourney prompts in seconds. Select subject, art style, medium, lighting, color palette, aspect ratio, and quality parameters. The builder assembles the full prompt with correct syntax — copy it directly into Midjourney, DALL-E, or Stable Diffusion.
Runs entirely in your browser — nothing is sent anywhere.
How to Build an AI Art Prompt
- Describe your subject — the main thing you want in the image.
- Select style, medium, lighting, and color options from the dropdowns or add your own.
- Set parameters (aspect ratio, quality, stylize) and click Copy Prompt to paste into Midjourney or another AI generator.
What Makes a Good AI Art Prompt?
The most effective AI image prompts are structured, specific, and layered. Rather than "a cat", a well-crafted prompt says "a tabby cat sitting on a windowsill, golden hour lighting, watercolor painting, soft pastel colors, --ar 4:3 --q 2". Each component guides a different aspect of the image: the subject, the mood (lighting), the aesthetic (art style and medium), the color story, and the technical output parameters.
Art style and medium are the biggest levers. "Oil painting" produces thick, textured strokes; "digital art" gives clean edges and vibrant colors; "pencil sketch" yields fine lines and crosshatching. Combining styles — "watercolor with ink outlines" — creates hybrid aesthetics. Referencing specific artists ("in the style of Alphonse Mucha" or "Studio Ghibli background art") gives the AI a rich visual vocabulary to draw from.
Lighting dramatically changes mood. "Golden hour" creates warm, cinematic glow. "Rembrandt lighting" adds dramatic shadow and depth. "Neon glow" produces cyberpunk atmosphere. "Soft diffused light" gives a gentle, editorial feel. Specifying lighting in your prompt is one of the fastest ways to elevate AI-generated images from average to professional-looking.
Frequently Asked Questions
What is a Midjourney prompt? ▼
A Midjourney prompt is a text description you send to the Midjourney AI image generator via Discord or the web app. The AI interprets the prompt and generates images. The more specific and structured the prompt, the more control you have over the result.
What are Midjourney parameters? ▼
Parameters are suffixes added to a prompt to control specific behaviors. --ar sets the aspect ratio (e.g., --ar 16:9 for widescreen), --q sets rendering quality (--q 2 for higher detail), --s sets stylization strength, and --v specifies the Midjourney version. This builder adds them automatically.
What is the aspect ratio parameter? ▼
The --ar parameter controls image dimensions. --ar 1:1 produces a square (good for profile pictures), --ar 16:9 a wide landscape (good for wallpapers and thumbnails), --ar 9:16 a vertical portrait (good for phone wallpapers and social posts), and --ar 4:3 a classic photo format.
What does the stylize parameter do? ▼
The --s (stylize) parameter controls how strongly Midjourney applies its aesthetic interpretation. --s 0 follows the prompt very literally with minimal style. --s 1000 applies maximum artistic interpretation. The default is --s 100. Use lower values when accuracy matters; higher values for more artistic results.
What is the chaos parameter? ▼
The --chaos parameter (0–100) controls how varied and unexpected the four generated image variations are. At --chaos 0, all four images are similar. At --chaos 100, they diverge wildly. Use higher chaos when you want to explore possibilities; lower chaos when you want consistent, predictable results.
Does this prompt builder work with DALL-E and Stable Diffusion? ▼
Yes. While the builder is optimized for Midjourney, the structured prompts — subject + style + medium + lighting + color — work well with DALL-E 3, Stable Diffusion, and Adobe Firefly. Skip the parameter suffixes (--ar, --q) when using non-Midjourney generators, as they use different syntax.
What is negative prompting? ▼
Midjourney supports the --no parameter to exclude elements: "a portrait --no hands" tries to omit hands. In Stable Diffusion, a separate "negative prompt" field lets you describe what you do not want. This builder includes a "Things to exclude" field that adds a --no clause automatically.
How do I get consistent character or style across images? ▼
Use the --sref (style reference) or --cref (character reference) parameters followed by a URL or previous image URL. You can also include a specific artist or series name in your prompt style section. Consistent lighting and color keywords also help maintain visual coherence.
