What makes a good AI prompt?

A good AI prompt scores highly across 8 dimensions: Clarity (clear objective), Specificity (precise details), Context (background information), Constraints (limits and rules), Format (output structure), Examples (reference samples), Tone (voice specification), and Persona (role assignment). The best prompts address all 8 dimensions to minimise ambiguity and maximise output quality.

How does the AI Prompt Checker score my prompt?

The AI Prompt Checker uses rule-based heuristic analysis to evaluate your prompt across 8 quality dimensions. It scans for keywords, structural patterns, and linguistic markers that indicate prompt engineering best practices. Each dimension is scored 0-100, and an overall score is calculated as the average across all dimensions.

Does the prompt checker send my data to any server?

No. The AI Prompt Checker runs entirely in your browser using client-side JavaScript. Your prompt text never leaves your device — no data is sent to any server, API, or third party. Your prompts remain completely private.

Which AI models benefit from better-structured prompts?

All major AI models benefit from well-structured prompts, including ChatGPT (GPT-4o), Claude (Anthropic), Gemini (Google), DeepSeek, Llama, Mistral, and others. Better prompts consistently produce more accurate, relevant, and useful outputs across every model.
