AI Prompt Generator
Build precise prompts for Midjourney, SDXL, Flux, DALL·E and Ideogram from structured choices — subject, style, lighting, camera, mood — with correct syntax for each.
Describe your subject
The subject is the only required field — everything else is optional seasoning.
Build the look
Medium
Style — pick as many as you like
Clicking a selected chip deselects it — every group except the subject can be left empty.
Format & negatives
Aspect ratio
Up to 33 adds nothing, 34–66 appends 'detailed', and 67 or higher appends 'intricately detailed, sharp focus'.
Things to avoid
Flux and DALL·E have no negative prompt — for those targets this list is left out.

What is AI Prompt Generator?
AI Prompt Generator assembles image-generation prompts from structured choices: your subject, plus a medium, style, lighting, camera angle, mood and palette chosen from curated lists, formatted in the exact syntax your generator expects. Midjourney gets its --ar and --no flags, Stable Diffusion gets a separate negative-prompt line, Flux and DALL·E get a natural sentence — because they respond to plain language better than to comma soup — and Ideogram gets its own conventions.
This is a builder, and says so
No AI runs on this page. It is a deterministic tool that turns your selections into correctly-formatted text, instantly and offline — which is precisely what makes it useful. The hard part of prompting is not inventing adjectives, it is remembering that Midjourney wants --ar 16:9 while SDXL wants a negative line and Flux wants neither; the builder holds that knowledge so you can think about the image instead. If you want a prompt derived from an actual picture, that is the Image to Prompt tool, which runs a real captioning model.
How to get prompts that work
Be concrete in the subject line — "a lighthouse on a basalt cliff at dawn, waves breaking below" beats "a beautiful lighthouse" in every generator. Pick one or two styles rather than five; stacked style tags fight each other. Lighting is the single highest-leverage choice on the page: the same subject at golden hour, under studio softboxes or lit by neon is three different images. And use negatives for things you actually keep getting — watermarks, mangled hands — not as a ritual.
The last ten prompts you copy are kept on this device so you can go back to what worked. Nothing is sent anywhere; there is no server side to send it to.
How to Use AI Prompt Generator
-
1
Pick your generator
Midjourney, SDXL, Flux, DALL·E or Ideogram — the output syntax follows your choice automatically.
-
2
Describe the subject
One concrete sentence: the thing, the setting, the moment. Press Inspire Me if you want a starting point to edit.
-
3
Build the look
Choose a medium, one or two styles, lighting, a camera angle, mood and palette. Lighting changes the image most.
-
4
Set format and negatives
Pick an aspect ratio and tick negatives you actually need. For Flux and DALL·E the builder omits negatives, because those models have no mechanism for them.
-
5
Copy and iterate
The prompt updates live in the sidebar. Copy it, generate, and come back — your last ten prompts are kept on this device.
