Page guide

Find Markdown links to headings that no longer exist. Runs locally and returns a reviewable report.

How to use Markdown Anchor Checker
  1. Paste the Markdown document.
  2. Run the local check.
  3. Review broken fragments and download the report.

Input is limited to 200000 characters. Results are computed locally and exported as JSON.

Heading slugs vary

The checker uses a common slug rule; compare the result with your renderer when punctuation or duplicate headings matter.
