A free, deterministic prompt quality checker that evaluates and optimizes AI prompts in under 10 milliseconds.

About AIQualityHQ

AIQualityHQ is a browser-based platform for evaluating and optimizing AI prompts, aimed at developers, prompt engineers, and security teams. It offers tools for static prompt analysis, injection vulnerability scanning, jailbreak detection, token cost estimation, and automated prompt refactoring. The platform runs most features locally in the browser, ensuring prompt data privacy and rapid analysis without external API calls. A free tier provides access to all browser tools and limited API usage, while paid plans unlock higher API quotas and cloud-based features. AIQualityHQ is designed to help teams catch prompt defects, enforce security guardrails, and optimize token usage before deploying AI applications.

Best for: AI developers, prompt engineers, application security teams

Key features

  • Analyzes prompt structure, constraints, and output schemas using deterministic rules in the browser.
  • Scans for prompt injection vulnerabilities and adversarial jailbreaks with dedicated detectors.
  • Estimates token usage, detects redundancy, and compares tokenizer efficiency across models.
  • Automates prompt refactoring and defect fixing, with visual side-by-side diffs.
  • Runs locally in the browser for privacy, with no prompt data sent to external servers.
  • Provides structured prompt synthesis and system prompt generation for production use.

Use cases

  • Checking prompts for structural issues and compliance before deploying to production.
  • Scanning for prompt injection and jailbreak vulnerabilities in AI applications.
  • Optimizing prompt length and token usage to reduce API costs.
  • Refactoring and fixing prompts automatically based on detected defects.

Pros

  • All browser-based tools are free to use with no card required.
  • Prompt data remains private as local tools do not upload content.
  • Very fast analysis, typically under 10 milliseconds in the browser.

Limitations

  • API usage is limited to 100 requests per hour on the free plan.
