HTML Accessibility Checker — Free WCAG Audit Tool

Paste your HTML for an instant structural accessibility audit computed in your browser: missing alt attributes, form fields with no label, skipped heading levels, duplicate IDs and missing landmarks. AI then writes the exact corrected markup for each issue it found.

How to use AI HTML Accessibility Auditor

1. Paste the HTML you want audited.
2. Review the local WCAG structural findings.
3. Let AI write corrected markup per issue.
4. Copy the fixes back into your code.

Frequently asked questions

Does this make my site fully WCAG compliant?

No. Automated checks catch structural issues but cannot judge things like meaningful alt text or logical focus order. Manual testing is still required.

Which issues are detected locally?

Missing alt text, unlabeled form controls, skipped heading levels, duplicate IDs, missing lang and missing landmarks — all without AI.

Can it audit a live URL?

Not directly — paste the rendered HTML (view source, or copy the DOM from devtools for JavaScript-rendered pages).
