The Free Fact Checker is a Chrome extension that enables you to select any text on a webpage and instantly fact-check it using Google Search and Gemini. It's instant research at your fingertips!

HOW IT WORKS ✅ Highlight Text — Select any statement on any webpage: news articles, social media, PDFs, AI chat, anywhere you can highlight text. Then use the right-click menu, keyboard shortcut or press the toolbar icon to trigger a fact check. ✅ Google Search Grounding — Your text is sent to Google Gemini, which finds real data about it using Google Search through a process called grounding. ✅ Get Cited Results — You get a fact-check with citations and sources. You will never get an AI's opinion — only answers grounded in Google Search.

GREAT FOR ✅ Verifying that AI is telling you the truth ✅ Checking your own work to make sure that you have things right ✅ Validating the truth of things you read on social media and in the news ✅ Quickly diving deeper into specific topics ✅ Anyone doing research - students, business professionals, etc.

There is no tracking or analytics. ✅ Check Your Writing — Highlight any text in your own writing and get instant fact-checks to ensure accuracy. ✅ Customize the Fact Check Prompt — Always want your results in Spanish?
