In Chrome, fact-checked posts are marked right in your feed, and everything else is scanned for warning signs as you scroll. polygraphs.ai/tools/extensio…

Watch it work: claims, searches and verdicts fill in live. You see the price before you start. If a post has already been checked, reading that check is free.

Then answer it. Polygraph drafts a reply from the fact check, with a card showing the verdict. Edit it and post it where the claim is spreading.

It shows how a post persuades, too: name-calling, bandwagon, slogans, scapegoating, quoted in the post's own words. A technique isn't a verdict. It's a reason to look closer.

Every claim gets a verdict: true, false, mixed or can't tell. Each one comes with the sources behind it, and each source is rated. Not just the headline claim. All of them.

Lies spread faster than the truth: on Twitter, false news reached people 6× faster than true news (MIT, 2018). Polygraph gives you the fact-fighting superpowers to stop them. Paste any post, page or video and it checks every claim, with the evidence. 🧵
