  • Checks organized by component, making it easy to test web pages one component at a time to ensure nothing is missed.
  • Checklist Builder tool automatically generates a tailored testing checklist for your audit based on the components you select and whether you want to include AAA-level checks.
  • Built-in WCAG Quick Reference sheet that provides WCAG success criteria, Conformance levels, Impacted disability groups, Clear explanations of each requirement, and links to further documentation
