Alt Text Auditor
Paste HTML — or give us a URL and we fetch it — and see every image that is missing alt text, and every one whose alt text says nothing.
Paste mode is offline: nothing is uploaded and nothing is fetched. View Page Source or Inspect, then paste. A fragment is fine — only img tags are read.
Paste some HTML above and the audit appears here.
