Midjourney Prompt Generator

Midjourney v6 prefers terse, evocative descriptions backed by parameter flags - the exact opposite of Flux's paragraph style. A great Midjourney prompt is 25–60 words, leading with a vivid subject + scene, followed by a few stylistic adjectives, a lighting note, and a camera or art reference. Then the flags: --ar to lock aspect ratio, --style raw for photorealism, optionally --chaos or --stylize to tune the creative latitude. Forget those and Midjourney will default to 1:1 and its house painterly look, which may not match your intent. This generator composes a prompt in Midjourney's native voice, picks a sensible --ar based on the subject (portraits → 2:3, landscapes → 3:2 or 16:9, square social posts → 1:1), and adds --style raw only when photorealism is called for. For reference-driven recreations, our Midjourney image-to-prompt tool handles the reverse flow, preserving the source aspect ratio in its --ar flag output.

Frequently asked questions

Do I need parameter flags for Midjourney?+
Yes. Midjourney v6 prompts always benefit from at least an --ar (aspect ratio) flag, and --style raw if you want photorealism. The generator picks a sensible aspect ratio and adds --style raw when the description suggests photographic intent.
What is an AI prompt generator?+
An AI prompt generator rewrites a short idea into a longer, model-specific instruction that steers an image model toward better, more predictable results. Different models prefer different prompt styles - Flux likes long natural language, Stable Diffusion likes a hybrid of description plus tags, Midjourney likes terse evocative phrasing with parameter flags, and Nano Banana 2 likes plain logical instructions.
Is the AI prompt generator free?+
Yes. Anyone can generate up to 5 prompts per day at no cost, no sign-up required. If you need more, the EdMyPic Free plan includes 5 photo edits per day plus unlimited prompt generation when signed in.
Which AI image models does this support?+
Eleven major models out of the box: Flux 1.1 Pro, Midjourney v6, DALL·E 3, Stable Diffusion 3, Stable Diffusion XL, Ideogram 2, Leonardo AI, Google Imagen 3, Google Nano Banana 2, Adobe Firefly, and Recraft V3. Each one ships with a hand-tuned system prompt - pick the model you'll be generating with so the output matches its conventions exactly.
How do I get the best results from a prompt generator?+
Start with a clear subject (who or what), a verb (what they're doing), and one stylistic anchor (e.g. golden hour, cinematic, watercolor). The generator handles the rest - composition, lens, lighting, and mood - based on the model you selected.
Can I use the generated prompt commercially?+
Yes. The prompt itself is just text - you own anything you generate from it. Commercial usage of the resulting image depends on the image model you're using; Flux, SD3, and Midjourney all support commercial output on their paid tiers.
Why does the same idea give different prompts for different models?+
Each model was trained on different data with different guidance objectives. A description that nails a photoreal portrait in Flux 1.1 Pro will under-perform in Midjourney unless you switch to Midjourney's more compact, flag-based syntax. The model selector handles that translation automatically.
Do I need to know prompt engineering to use this?+
No. The whole point of the tool is that you don't. Type a rough idea like "a barista smiling at golden hour" and you'll get back a fully-formed prompt that incorporates the photography, composition, and mood cues the model needs.
