How to use the Prompt Improver
Paste a prompt you already use and this checker scores it against the habits that consistently produce better answers from large language models. It looks for a stated role or persona, a clear action verb, enough context, an explicit output format, length guidance, constraints on what to avoid, examples, and the target audience. Each missing element is listed with a short explanation so you understand why the change matters instead of just copying a template.
Below the score you get an improved version of your prompt. The tool keeps your original wording as the core task and wraps it in a structured scaffold, adding placeholder sections for the parts you skipped. You then replace the bracketed placeholders with real details. This is deliberately transparent: no hidden AI rewrites your intent, so the final prompt still says exactly what you mean.
The checker is rule based and runs entirely in your browser, so it is instant, free and private. It is useful for teams writing shared prompt libraries, students learning prompt engineering, and anyone who notices that their AI answers feel vague. A score of 80 or more usually means the prompt is specific enough; below 50 the model is probably guessing too much.
Frequently asked questions
How is the score calculated?
Each checklist item (role, task verb, context, format, length, constraints, examples, audience) adds points. The total is shown out of 100.
Does a high score guarantee a good answer?
No, but specific prompts reduce guessing. Always review AI output for accuracy.
Does it use AI to rewrite my prompt?
No. The improvement is a transparent structured template built from your text, run locally in the browser.
Can I use it for image prompts?
It is tuned for text models. For Midjourney or Stable Diffusion use the AI Image Prompt Builder.
