Description
FACT CHECK WHILE YOU READ.
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.
HOW IT WORKS
✅ Highlight Text — Select any statement on any webpage: news articles, social media, PDFs, 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.
FEATURES
✅ Works Everywhere — Websites, PDFs, Google Docs & Google Slides — any page where you can highlight text.
✅ Grounded in Search — Results come from Google Search, not AI opinion. If no data can be found, it will tell you instead of making something up.
✅ 100% Free — The extension is free. Google lets you make 20 grounding requests per day with a free Gemini API Key.
✅ No Login Required — Use it immediately after installing and adding your API key.
✅ No Tracking — Your queries go directly from your browser to Google's API using your own key. 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? No problem, just add it to the prompt.
✅ Source Code Available — Download it, review it, install it, fork it, edit it.
