What is Link Checker?
A link extractor and checker. It lists every link in a Markdown document and, on request, pings each URL from your browser to flag broken ones.
How it works
Links are parsed from Markdown syntax, then fetched via the browser (subject to CORS — some URLs can't be checked, which is expected).

Frequently asked questions
Why do some links show 'could not check'?
Browsers enforce CORS, so some servers block cross-origin requests. A link that can't be checked isn't necessarily broken — it's a browser security limitation.
