Midjourney prompt generator — vivid AI art prompts under 350 chars

HotPrompt's Midjourney prompt generator emits a single flat, comma-delimited prompt ending in --ar and parameter flags — exactly how Midjourney likes them — with a negative prompt line for clean results.

Before vs After

Before vs after — a tag-style Midjourney prompt that composes

Midjourney rewards flat, comma-delimited prompts that end in parameter flags. Skip the prose; lead with the subject; finish with --ar and --no.

How it works

How to write a Midjourney prompt that actually composes

Midjourney prefers a single flat line ending in parameter flags. Four steps to get there without a prompt-engineering PhD.

01
Lead with the subject
Subject first, then style, then context — the generator structures the comma-separated order for you.
02
Add the look
Lens, lighting, palette, era — described in tags the model recognizes.
03
Cap at ~350 chars
Midjourney truncates long inputs. The optimizer fits everything into a clean, parseable line.
04
Append the flags
--ar, --stylize, --v, --no — sensible defaults you can tweak, baked into every output.

What you get from this Midjourney prompt generator

Midjourney wants a single flat line ending in parameter flags — every output respects the format.

Subject → style → context → camera/lens → palette → grade (the order MJ parses best).
Parameter flags appended (--ar, --stylize, --v, --niji when relevant).
--no negative prompt killing common artifacts (warped faces, text, watermarks).
350-char cap so MJ never truncates the prompt mid-clause.
Style references and director-of-photography names that MJ recognizes.
Niji v6 anime mode when the idea is anime — without you having to ask.

Built for Midjourney v6 / v7's quirks

Each MJ version has its own personality. The generator picks the right vocabulary so the output composes cleanly.

v6/v7 loves descriptive subjects

Specific subject details (breed, age, wardrobe, posture) land better than abstract style words.

Parameters, not prose

MJ ignores 'please make it widescreen' but obeys --ar 16:9. We use parameters everywhere we can.

Negatives via --no

--no people, signage, text, watermark, low contrast kills 80% of common failures.

Style refs work

When you have an --sref image URL, the generator slots it in correctly so the style transfer applies.

Use cases this Midjourney prompt generator earns its keep on

Anywhere a high-quality image saves a stock-photo subscription or a designer's afternoon.

Brand designers

Mood boards, hero shots, reference plates — generated in seconds with --ar matching the brief.

Indie game artists

Concept art, tileable textures, character refs — the negative line keeps text and watermarks out.

Authors

Book covers, chapter visuals, character portraits — atmospheric grades chosen for the mood you brief.

Marketing teams

Landing-page heroes, ad creative, social cards — --ar 16:9 or --ar 9:16 switched in one click.

Questions

Frequently asked about this tool

What's the right --ar / --stylize for Midjourney v6?

Defaults the generator picks: --ar 16:9 for cinematic, --ar 1:1 for square social, --ar 9:16 for vertical. --stylize 250 is a sweet spot — high enough to be artful, low enough to respect the subject. You can always tweak after.

Can this generate anime / Niji prompts?

Yes — when your idea mentions 'anime', 'manga' or specific anime references, the generator switches the parameter from --v 6 to --niji 6 and tightens the subject vocabulary for Niji's strengths.

Does this work for Stable Diffusion / Flux / DALL·E too?

Yes for SD and Flux — the tag-style format is what they want. DALL·E 3 prefers more natural language; for DALL·E targets, the generator switches to descriptive prose with the same subject/style/composition coverage.

Why is the Midjourney length capped at 350 characters?

Midjourney has historically capped its prompt window around that length. Going longer often gets the trailing instructions truncated. The generator respects the cap so every word counts.

How is this different from copying tag lists off Lexica or PromptHero?

Those are static lists. HotPrompt rewrites your specific idea into a structured tag list — same shape, but actually about what you want. It also adds the --no line, which the random Lexica copy-paste usually skips.
