How to use
- Paste the prompt you want to check.
- Click “Generate” to see the score and elements (✓ present, ○ missing).

Why use this tool?
The check is based on well-known elements of good prompts: role, context, objective, constraints, output format, examples and structure. The score is a quick structure indicator, not a judgment of the final answer.
Frequently asked questions
How is the score calculated?
By the presence of key elements in your prompt (role, context, objective, constraints, output, example, structure); each one adds points.
Is the check done with AI?
No, it uses local rules in your browser — fast and private.
High score but weak answer — why?
The score measures structure only. Try clarifying the goal or adding an example of the answer you want.
