View your galleryAgent-Ready Audit & Bug Hunter
Enter any URL and watch AI analyze your site in real time. These tools find issues that manual testing misses. They reveal friction points that frustrate both humans and AI agents.
Agent-Ready Audit
Scores your site on 5 dimensions. These show how easily AI agents and humans with disabilities can navigate it:
- Findability — Can elements be located by intent?
- Stability — Do selectors survive DOM changes?
- Accessibility — ARIA labels, semantic HTML, keyboard nav
- Semantics — Meaningful structure for AI parsing
- Overall Grade — A+ to F readiness score
Hunt Bugs
AI-powered bug detection that finds issues human testers miss. Explores your site like a real user and reports:
- Broken Links — 404s, redirects, dead ends
- Console Errors — JavaScript exceptions, failed requests
- Accessibility Violations — WCAG issues on mobile and desktop, with severity
- Visual Anomalies — Overlapping elements, broken layouts
- UX Friction — Confusing flows, missing labels
The insight: Sites built for accessibility use clear structure, semantic HTML, and predictable patterns. These are the same sites AI agents navigate with ease. If it works for a screen reader, it works for an AI.
