AI-Powered WCAG Accessibility Scanner
Comprehensive web accessibility analysis combining Google Lighthouse with AI vision models for deeper, context-aware WCAG compliance reports.
AccessHawk scans any public webpage and generates a detailed WCAG compliance report in seconds. Unlike traditional rule-based scanners that only catch ~30% of accessibility issues, AccessHawk combines:
- Google Lighthouse for deterministic rule-based checks
- AI Vision Models for contextual analysis of user experience, visual hierarchy, and semantic meaning
The result is a comprehensive report that catches issues traditional scanners miss—like alt text that exists but doesn't actually describe the image, or navigation that's technically valid but confusing to use.
