❓ FAQ

Will the anchors match GitHub exactly?

Yes. Our slugger mirrors GitHub: lowercased, non-alphanumeric stripped, spaces become hyphens, emojis removed, and duplicates suffixed with -1, -2…

Is my Markdown sent to your server?

No. All processing is in your browser via plain JavaScript. You can verify in the Network tab.

Are # signs inside code blocks ignored?

Yes. Fenced code blocks (``` and ~~~) are excluded from heading detection. Inline code hashes are skipped too.
