Calculating…
Who uses it, and for what
Produce on-brand product and lifestyle shots with the same light and palette every time.
Get the right aspect ratio for feed, reel or banner without cropping later.
Save prompt recipes per client so anyone on the team gets consistent results.
How this tool works
Orders the prompt the way models read it
Subject first, then setting, style, light and camera. Image models weigh early words more.
Outputs two formats
A universal sentence for Flux, GPT Image, Gemini or Ideogram, and Midjourney syntax with --ar and --no.
Keeps negatives separate
What to avoid goes in its own clause, so it does not get mixed with what you want.
Frequently asked questions
Which model should I use?
Any of them work with the universal prompt. If you want to generate directly, the PURIST AI Studio runs several image and video models.
Why does my image include text?
Add "text, letters, logos" to the Avoid field, and avoid words like "poster" or "sign" in the subject.
How do I keep a consistent style?
Reuse the same style, light, camera and colour choices across prompts and change only the subject.
