Fact Sentinel

Protect yourself from misinformation. Auto-detects false claims as you browse + instant verification on demand.

In a world where misinformation spreads faster than ever, Fact Sentinel puts the power of AI-driven fact-checking directly in your browser. Whether you're scrolling through social media, reading news articles, or researching online, Fact Sentinel works quietly in the background to identify questionable claims and alert you before you unknowingly share false information. Fact Sentinel offers two powerful ways to verify what you read. The automatic passive monitoring feature continuously scans the pages you visit for potentially misleading claims, displaying a subtle notification when something doesn't check out. For times when you want to verify a specific statement, simply highlight any text and right-click to get an instant fact-check powered by advanced AI analysis. Within seconds, you'll receive a clear verdict along with a detailed explanation of why a claim is accurate, misleading, or outright false. What makes Fact Sentinel different is its commitment to transparency and user choice. You can use our managed platform with generous free limits, or bring your own OpenAI or Anthropic API keys for unlimited private fact-checking where your queries never touch our servers. Every verification includes confidence scores and source-backed explanations so you understand exactly why a claim was flagged. Fact Sentinel is designed to be helpful without being intrusive. The extension only activates on the sites where misinformation is most common, including news outlets, social media platforms, and blogs. Smart notification throttling ensures you're informed about important findings without being overwhelmed. The clean, modern interface stays out of your way until you need it. Stop second-guessing what you read online. Install Fact Sentinel today and browse with confidence knowing that AI-powered verification is always just a click away. Join thousands of users who have already made fact-checking an effortless part of their daily browsing.
