Audit tools: - WCAG 2.2 audit engine with viewport-specific reports - Issue overlay that highlights failing elements on the page - Copyable HTML, CSS and ARIA code-fix suggestions for each finding - Accessibility score badge (Aโ€“F) in the URL bar - Structure inspector: heading tree, landmark regions, tab order - Contrast picker and full element inspector - Before and after audit comparison to verify fixes Free, always. No account, no sign-in, and nothing to unlock โ€” every feature works on first launch, fully on-device. No analytics. No tracking. No third-party SDKs.
