FactChecker Pro

Real-time AI-powered fact-checking with credibility scores, claim detection, source analysis, and misinformation alerts.

Stop misinformation before it spreads. FactcheckerPro is a free browser extension that works silently in the background while you browse, and speaks up the moment it detects a false or misleading claim on the page you are reading. Whether you are scrolling through X (formerly Twitter), reading a news article, or following a breaking story on Facebook, FactcheckerPro gives you an instant credibility rating — no copy-pasting, no switching tabs, no extra steps. Just click and know. What FactcheckerPro does When you land on a page containing a claim that has been fact-checked or flagged by our source network, a popup appears within seconds showing you the credibility rating and the sources behind it. You stay in control: the popup is non-intrusive, and silent mode keeps things quiet when you just want to read. FactcheckerPro checks claims against a growing network of verified sources and community contributors called the Beacons of Truth — real people who care about accuracy and contribute to a shared, open knowledge base. Key features Real-time fact-checking as you browse with no manual steps required Credibility score popup that appears in under 2 seconds on flagged content Works across major platforms including X, Facebook, news sites and blogs Silent mode for distraction-free browsing with alerts only when it matters Beacons of Truth leaderboard where contributors earn recognition for accuracy Full browsing history of every claim checked, so you can review and compare User profile with your fact-checking activity and community standing Built for people who care about truth Journalists, researchers, students, teachers and anyone who wants to read the internet with more confidence. FactcheckerPro was built on the belief that catching misinformation should be effortless, and that the people who catch it should be celebrated, not ignored. One of our early testers described it this way: the extension correctly flagged a known false claim about election fraud on X within 2 seconds of landing on the page. That is the experience we designed for. A community, not just a tool The Beacons of Truth model means you are not just a passive user. You are part of a network of people who hold information to a higher standard. Students, researchers and professionals are already using FactcheckerPro as part of their daily reading routine because it rewards accuracy and turns fact-checking into a shared mission rather than a solo chore.
