About AIQualityHQ

AIQualityHQ is a free online prompt checker designed to help developers and creators evaluate, score, and improve their AI prompts for production use. Powered by a deterministic Quality Engine, the tool parses prompt text locally in the browser, delivering comprehensive analysis in under 10 milliseconds without requiring paid API calls or account registration.  

The engine evaluates prompts across six core dimensions: Prompt Structure, Memory & State, Context Grounding, Trust & Accuracy, PII & Privacy, and Security & Safety. Each dimension provides a clear 0-100 score based on specific pass/fail rules, successfully flagging hallucination risks, potential prompt injection vulnerabilities, and context boundary violations.  

Beyond just scoring, AIQualityHQ provides actionable fix suggestions and automated checklists so users can immediately optimize their prompts. It is fully model-agnostic, improving interactions across all major LLMs like GPT-4, Claude, Gemini, and Llama.
