Frequently asked questions
Does it check if links work?
Browsers cannot fetch other sites, so reachability is not checked — this validates the Markdown itself. Nothing is uploaded.
What does it flag?
Empty URLs and URLs containing spaces, which break rendering.
Is it private?
Yes. Everything runs locally in your browser; nothing is uploaded.
