About Promptkoi
Promptkoi is a curated library of AI image prompts that actually work. Every prompt we publish has been run on the model it targets — Midjourney, Stable Diffusion, DALL·E or Flux — and ships with the image it produced, the exact settings we used, and notes on how to adapt it to your own subject.
Our testing methodology
Every prompt on this site follows the same process before it's published:
- Written from scratch. We study what works across the community, but every prompt is our own wording — never copied from another site or marketplace.
- Generated on the model it's written for. A Midjourney prompt is tested in Midjourney, an SDXL prompt in Stable Diffusion. The example image you see is what the prompt actually produced — we note the model version with every entry.
- Settings recorded. Aspect ratio, stylize, steps, CFG, sampler — whatever the model exposes, we publish, because the same words behave differently under different settings.
- Explained. Each entry includes usage notes on which phrases carry the result and variations worth trying — so you learn the "why", not just the "what".
Our content principles
- All example images are generated by us — nothing is scraped or reposted.
- Everything on the site is safe for work, always.
- Prompts are free to copy and use for your own generations, personal or commercial.
- Where we recommend tools, some links may be affiliate links — always disclosed, and never the reason a tool gets recommended. See our Affiliate Disclosure.
