FactChecker Pro tells you before you share it. Synthetic videos. AI-written posts passing as human opinion. Recycled photos reused to fuel outrage. Coordinated disinformation masquerading as breaking news. In 2026, the volume of AI-generated content on social media makes it nearly impossible to tell what is real and what is manufactured. FactChecker Pro is the only browser extension that fights all of it at once, across every platform where it happens, in real time. As you scroll through any feed, a badge bar appears on every post. You see an AI confidence score, a visual risk indicator, and a one-click fact-check button without ever leaving the platform. No extra tabs. No copy-paste. No workflow interruption. 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 & Three distinct categories of threat detected on every post: AI-Written Text The heuristic engine analyses each post across six dimensions: 34 known AI phrase signatures, sentence length uniformity, contraction frequency, formality signals, amplification language, and synthetic visual captions. Posts score 0 to 100 with a clear label at each threshold. Synthetic Visuals and Deepfakes When a post contains video and the AI text score reaches medium risk or above, a red warning overlay is injected directly onto the video thumbnail in the feed, visible before you click play. Platform-Native AI Disclosures When TikTok stamps a video "This content is AI generated," when YouTube shows an AI-generated content disclosure, when Instagram or Facebook display "Made with AI," FactChecker Pro reads that platform signal directly and immediately shows a high-confidence badge. 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.
