  description

  A browser extension for Chrome and Microsoft Edge that instantly analyzes any web page or selected text for disinformation, misinformation, and false claims — powered by xAI's Grok AI with real-time Live Search.

  Grok Disinformation Checker brings AI-powered fact-checking directly into your browser. Powered by xAI's Grok models and real-time Live Search, it analyzes any web page or highlighted text for disinformation, misinformation, propaganda, and misleading claims — in seconds.

  ✨ KEY FEATURES
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  
  🔬 One-Click Page Analysis
  Click the extension icon and hit "Check Full Page" to scan an entire article, news story, or website for factual accuracy.
  
  ✂️ Selected-Text Analysis
  Highlight any sentence or paragraph, right-click, and choose "Check with Grok" — or click the "Check Selection" button — to fact-check just that snippet without sending the whole page.
  
  📊 Visual Trust Score (0–100)
  Every analysis returns a color-coded trust score displayed as an animated ring:
    • 🟢 80–100 → LOW risk (accurate, well-sourced)
    • 🟡 50–79  → MEDIUM risk (some unverified elements)
    • 🟠 30–49  → HIGH risk (significant misinformation)
    • 🔴  0–29  → CRITICAL risk (severe disinformation)
  
  🔍 Real-Time Live Search
  Grok searches the web in real time to cross-reference claims against current news, data, and sources — not just its training knowledge.
  
  ⏳ Background Analysis
  The API call runs in the extension's service worker, so analysis continues even if you switch tabs while waiting for results. Come back whenever you're ready.
  
  🕐 Analysis History
  Your last 20 analyses are saved locally. Each history entry shows a direct 🔗 link back to the original article, and "Re-analyze" opens that URL in a new tab and queues a fresh check automatically.
  
  🔗 Clickable Source Links
  When issues are found, each issue card includes a clickable link to a more accurate source so you can read the truth directly.
  
  📋 Copy Report
  Export a full plain-text analysis report to your clipboard with one click — great for sharing or archiving.
  
  ⌨️ Keyboard Shortcut
  Press Alt+Shift+G to trigger a page analysis instantly, without opening the popup.
  
  🖱️ Right-Click Context Menu
  Right-click on any page or selected text to check for disinformation directly from the context menu.
  
  🤖 Auto-check Pages (Optional)
  Enable Auto-check in Settings to have every page you navigate to analyzed automatically in the background. Off by default — enable it intentionally as it uses API credits on every page load.
  
  🏷️ Per-Tab Toolbar Badge
  The trust-score badge on the extension icon is tab-specific. It only appears when Auto-check is enabled and the current page has been checked. It clears automatically when you switch tabs or navigate away.
  
  ⚙️ Configurable Settings
    • Choose your Grok model (Grok 4 Fast Reasoning, Grok 4, Grok 3, Grok 2)
    • Toggle Live Search on or off
    • Enable/disable auto-detection of selected text
    • Enable/disable Auto-check Pages (off by default)
    • Enable/disable the toolbar badge
    • Clear history or all data with one click
  
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  🔒 PRIVACY-FIRST DESIGN
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  
  • Page content is sent ONLY to the Grok API (api.x.ai) — nowhere else.
  • Your API key is stored in your browser's own secure storage, never on any external server.
  • The developer receives zero telemetry, analytics, or user data.
  • All history is stored locally on your device.
  • Uninstalling removes all data automatically.
