How does the AI Prompt Scorer work?
The scorer analyzes your prompt across 5 key dimensions of prompt engineering: specificity, context, role assignment, output format, and constraints. Each dimension is scored 0-20 using pattern matching, giving you a total score out of 100 with actionable improvement tips.
Is the Prompt Scorer really free?
Yes, 100% free with no signup required. Score as many prompts as you want. Everything runs in your browser — we never store or see your prompts.
What score should I aim for?
Anything above 70 is good. Above 80 is excellent and will produce consistently high-quality AI output. Our premium prompt kits are engineered to score 90+.
Does this work for image/video prompts too?
The scoring criteria are optimized for text-based AI prompts (ChatGPT, Claude, Gemini). Image and video prompts follow different rules, though specificity and detail still matter.
Why is my prompt scoring low?
Most people write prompts that are too vague. The most common issues are: no role assignment, no output format specified, and no constraints. Adding these three elements alone can boost your score by 30-40 points.
