WHEN TO USE IT
Built for this specific task
- Fix vague prompts that produce inconsistent answers
- Reduce unsupported claims through explicit evidence rules
- Rebuild a prompt around a machine-readable output schema
EXAMPLE
Input
Original: Write a useful market analysis. Failure: it invents statistics. Optimize for structured output and lower hallucination.
Output preview
A revised prompt that separates supplied evidence from inference, defines table fields, requires unknown values to be marked, and includes a verification checklist.
KNOW BEFORE YOU GENERATE
Limits and review checklist
- Optimization cannot eliminate every model error or hallucination
- The result is only validated after testing it with realistic inputs and edge cases
COMMON QUESTIONS
Frequently asked questions
Will the optimizer change my original goal?
It preserves the stated intent and any content you lock, while making missing context and ambiguous instructions explicit.
Can I include an example of a bad response?
Yes. A failure example helps the optimizer address the exact behavior you want to prevent.
How is this different from a prompt generator?
This tool diagnoses and improves a prompt you already have; the generator builds a new prompt from a goal.
