Paste a link to an Arc article. Your browser does the math itself: it checks our signature and confirms the article is in our public log.
What this does and doesn’t prove
It proves the article matches what Arc signed and logged. It doesn’t prove our analysis is right, or that the original story is true.
This page’s code and the data it checks both come from our server, so a fully compromised Arc could fool it. For a check that doesn’t depend on us at all, use the Python checker with a saved copy of our key.
