This does what it says: runs accessibility audits against your web or mobile UI to catch WCAG compliance issues. You give it scope (which pages, which WCAG level, which user flows), and it walks through automated scans plus manual keyboard and screen reader checks, then maps findings to specific criteria with severity and remediation steps. It's built for teams that need to document compliance or fix barriers before launch, not just get general design feedback. The playbook resource suggests it has detailed procedures for tooling and retesting, which is helpful if you're setting up repeatable audit practices. Solid if accessibility is a hard requirement and you need structured findings, less useful if you're just curious whether your color contrast passes.
