A LITTLE MORE CLARITY
Before and after: prompt optimization
An illustrative input and output. Your result will depend on your task.
THE STARTING POINT
Summarize this report. Keep it under 200 words.
A CLEARER PROMPT
Summarize the report provided below in no more than 200 words. Cover the main findings, important supporting evidence, and stated limitations. Do not add information that is not present in the report. Report: [Paste report here]
The revision keeps the report-summary goal and 200-word limit. It clarifies what to cover, rules out unsupported details, and marks where to paste the report.
GOOD TO KNOW
Prompt Optimizer FAQ
Is it free to use?
Yes. No account is needed. Fair-use limits and shared capacity limits help keep the tool available. Access is not unlimited.
What does the optimizer change?
It improves clarity, removes ambiguity, and makes useful output requirements explicit. It should preserve your goal, existing variables, and stated constraints. A short prompt may need only a small edit.
Will an optimized prompt always perform better?
No. A clearer rewrite is a candidate you should review and try. This tool does not run your original and revised prompts on a test set or guarantee better results from every model.
Can I ask for a shorter prompt?
Yes. Open Additional requirements and ask for a shorter version. The optimizer should remove unnecessary wording while retaining your task and explicit requirements.
Does it keep my original prompt?
The comparison shows the original input used for the successful result. If you edit the input or a new request fails, the previous comparison remains available. It is not saved as a history after you leave the page.
Can it add a JSON output requirement?
Yes. Add “The final answer should be valid JSON” in Additional requirements. That requirement will be written into the revised prompt; the optimizer does not execute the final task itself.
What if the original prompt is missing information?
Necessary facts can be left as labeled placeholders. Review them and fill in accurate details. The optimizer should not make up facts, personal experience, statistics, or business context.
