AI Prompt Optimizer

Paste an existing prompt. The optimizer sorts each part into the building blocks most image and video models respond to, rebuilds the prompt in a clear order, and tells you which parts are missing.

How to use it

  1. Paste your prompt and choose image or video.
  2. Press Optimize to see each part sorted into a section.
  3. Fill in anything marked missing, then copy the rebuilt prompt.
  4. Use Compare to see exactly what changed.

Frequently asked questions

How does it decide which section a phrase belongs to?

It uses keyword rules, for example “35mm” or “close-up” goes to camera and “golden hour” goes to lighting. It is a fast helper, not a language model, so check the result. Phrases it cannot place stay with the subject.

Will the optimized prompt always be better?

Not always. A clear order and no missing parts usually helps, but the only real test is generating with your model. Use the comparison tool to keep the version you prefer.

Does my prompt get stored?

No. The text is processed in your browser and is not sent to the server.
