What is Grok Disinformation Checker
Instantly analyze any web page or selected text for disinformation and misinformation using 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)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 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.
