Launch ACEACE provides automated accessibility remediation powered by AI and structural tagging. While ACE significantly improves WCAG 2.1 AA, Section 508, and PDF/UA compliance, some issues may require manual review by a qualified accessibility specialist. ACE does not guarantee full regulatory compliance. Results vary by document complexity, source formatting, and content type. ACE is a tool to assist — not replace — professional accessibility auditing.
