About AIQualityHQ

AIQualityHQ is a dedicated platform designed to help developers, prompt engineers, and creators measure, improve, and trust every AI interaction. The core of the platform is a free, local, deterministic Quality Engine that parses prompt text instantly in the browser—delivering granular scores and diagnostics in under 10 milliseconds without requiring an API key.

The engine evaluates prompts against strict pass/fail criteria across six essential dimensions:

Prompt Structure: Analyzes formatting and system role clarity.

Memory & State: Evaluates context window management.

Context Grounding: Measures reference usage and alignment.

Trust & Accuracy: Flags hallucination risks (weighted highest at 25%).

PII & Privacy: Detects unintended sensitive data exposure.

Security & Safety: Scans for prompt injection vulnerabilities.

Beyond raw scoring, the tool provides specific, actionable fix suggestions and a checklist to optimize prompts for production environments. It works universally across all major language models (GPT-4, Claude, Gemini, Llama) and securely caches version history locally in the browser storage to allow side-by-side revision comparisons.
