Midjourney Prompt Builder (--ar · --v · --stylize · --chaos) | RECATOOLS

How to Use the Midjourney Prompt Builder

Describe the subject

Start with the main thing in the image — the noun phrase the picture is about. Be concrete: "a lone lighthouse on a rocky cliff at dawn" beats "a nice scene". This is the part that drives the composition.

Add style and details

List the look you want — medium, lighting, mood, lens, art movement. "cinematic lighting, golden hour, 35mm photograph" tells Midjourney how to render the subject without changing what it is.

Tune the parameters

Pick an aspect ratio and version, then adjust stylize, chaos, weird, quality, exclude (--no), seed and tile as needed. The builder only appends a flag when it differs from the default, so your command stays clean.

Copy into Midjourney

Hit Copy, then paste after /imagine prompt: in Discord or the Midjourney web app. Everything is assembled in your browser — nothing you type is sent anywhere.

Parameters Are Where Midjourney Prompts Are Won or Lost

The prompt is the words; the flags are the dials

A Midjourney prompt has two distinct halves, and confusing them is the most common reason images come out wrong. The first half is the description — a subject and a set of style details written in plain language. The second half is a row of parameters, the double-dash flags like --ar and --stylize that sit at the end of every command. The description tells Midjourney what to draw; the parameters tell it how the rendering engine should behave. You can write a beautiful description and still get a frustrating result if the flags fight you — a portrait subject squashed into a --ar 16:9 frame, or a clean product shot drowned in a high --stylize value that adds painterly flourishes you never asked for.

Aspect ratio (--ar) is the highest-impact flag because it decides the canvas before a single pixel is generated. A 9:16 vertical frame composes a scene completely differently from a 21:9 cinematic one — the same words produce different crops, different negative space, and different focal points. Choosing the ratio up front, rather than cropping afterward, lets Midjourney actually arrange the composition for the shape you want. Version (--v, or --niji for the anime-tuned model) is the second pillar: each model release re-balances realism, coherence and prompt-following, so "v7" and "niji 6" are effectively two different artists interpreting the same brief. A description that sings in one version can feel flat in another, which is why pinning the version makes your results comparable from one run to the next. Those two flags are non-negotiable enough that this builder always includes them, even at their defaults, so the command is explicit and reproducible.

"The description is the brief. The parameters are the studio settings. Most disappointing renders are a great brief shot with the wrong settings."

Use the stylization dials with intent

The remaining flags are aesthetic dials, and the trick is to move them only when you have a reason. --stylize controls how much of Midjourney's own artistic opinion gets layered onto your prompt: low values stay literal and obedient, high values grow more decorative and interpretive. --chaos increases the variety across the four images in a grid, which is useful when you are exploring and counter-productive when you have already found your look. --weird pushes toward the unconventional and offbeat, a deliberate detour from the expected. --q (quality) trades render time for detail, and --no subtracts unwanted elements — write --no text and Midjourney works to keep lettering out of frame. --seed locks the random starting point so you can reproduce or iterate on a result, and --tile produces a seamless repeating texture for wallpapers and fabrics. Because every one of these has a sensible default, the cleanest commands include only the dials you actually turned — which is exactly what this builder assembles for you, appending a flag solely when its value departs from the default. Fill the fields, watch the command build live, copy it, and paste it straight into Midjourney.

10 Facts About Midjourney Prompts

01

Parameters are the double-dash flags at the end of a command — --ar, --v, --stylize and more.

02

Aspect ratio (--ar) sets the canvas before generation, so it shapes the whole composition.

03

--niji selects the anime-tuned model — a different artist from the standard --v versions.

04

--stylize (0–1000) controls how much of Midjourney's own aesthetic is layered on; lower stays literal.

05

--chaos (0–100) increases how different the four grid images are from each other.

06

--weird (0–3000) pushes results toward the unconventional and offbeat.

07

--no subtracts elements — --no text tells Midjourney to keep lettering out of frame.

08

--seed locks the random starting point, making a result reproducible across runs.

09

--tile produces a seamless repeating texture — ideal for wallpapers and fabric patterns.

10

This builder runs entirely in your browser — your prompt is never uploaded.

Frequently Asked Questions

It is a form that assembles a clean Midjourney command for you. You type a subject and style, pick parameters like aspect ratio, version and stylize, and the tool produces the full prompt with its -- flags — ready to paste after /imagine prompt: in Discord or the Midjourney web app.
Into Midjourney's prompt field. In Discord, type /imagine, then paste the command after prompt:. In the Midjourney web app, paste it into the imagine bar. The output is plain text, so it works wherever Midjourney accepts a prompt.
No. The command is assembled entirely in your browser with plain JavaScript. Nothing you type is sent to Midjourney, any model, or any third party from this page, and nothing is saved.
By design. A flag is only added when its value differs from the default — so --stylize appears only if you change it from 100, and --chaos only if it is above 0. Aspect ratio and version are always included so the command is explicit and reproducible.
It controls how much of Midjourney's own artistic style is applied on top of your description. Low values (toward 0) stay literal and obedient to your words; high values (toward 1000) become more decorative and interpretive. The default is 100.
--v selects a standard Midjourney model version (such as v7 or v6.1). --niji selects the Niji model, which is tuned for anime and illustration styles. Selecting "niji 6" in the builder outputs --niji 6 instead of a --v flag.
--chaos (0–100) controls how varied the four images in a grid are from one another — higher means more diverse options. --weird (0–3000) pushes the aesthetic itself toward the unconventional and offbeat. One increases spread; the other increases strangeness.
--no is negative prompting: it asks Midjourney to leave certain elements out. Type a comma-separated list in the Exclude field — for example text, watermark, blur — and the builder appends --no text, watermark, blur to your command.
Use a seed when you want reproducibility. Re-running the same prompt with the same seed gives a consistent starting point, which is handy for iterating on a look or making controlled small changes. Leave it blank to let Midjourney pick a random seed each time.
Completely free, with no account or sign-up and no limit on use. It runs in your browser and collects no data. You still need your own Midjourney subscription to actually generate images.
