2 upvotes
AIQualityHQ is a free, browser-native AI prompt quality checker and LLM tool suite that analyzes prompts across six core dimensions: Structure, Memory, Context Grounding, Trust & Accuracy, PII & Privacy, and Security & Safety. It uses a deterministic rule engine to produce a diagnostic report in under 10 milliseconds.
The suite includes a System Prompt Generator, Prompt Quality Checker, Token Optimizer, Injection Scanner, and an AI Auditor tool. Because it runs 100% locally in the browser, prompt data is not transmitted to external servers, with no API costs or rate limits—making it suitable for production prompt evaluation and security-focused QA workflows.
Open suite in browser
User loads AIQualityHQ in the browser and selects the relevant tool (generator, checker, optimizer, scanner, or auditor).
Run analysis on a prompt
User pastes a system prompt or test prompt and runs the deterministic evaluation across the six quality dimensions.
Review report and iterate
User checks the diagnostic report and recommendations, then updates the prompt and re-runs until quality and security criteria are met.
AI prompt engineers, AI developers, and QA teams who need fast, repeatable prompt evaluation during development and testing. Teams focused on prompt security, privacy, and token-budget control benefit most from the local, deterministic workflow.
