FactChecker Pro is a Google Chrome extension that analyzes web pages in real time, scores their credibility, detects suspicious claims, and connects you to a global community of fact-checkers. It rewards active users with a Transparency Score reflecting the quality of their contributions.

FactChecker Pro is a free Chrome browser extension that analyses web pages in real time to detect unverified claims, score source credibility, and alert users to potential misinformation. It works automatically in the background as you browse.

FactChecker Pro is built for anyone who reads news online — including students, researchers, journalists, educators, and everyday readers who want to verify what they read before sharing it.

The core features are completely free to use. A free account gives you access to claim detection, credibility scoring, your personal Transparency Score, and your submission history. Premium features may be introduced in future updates.

FactChecker Pro currently supports Google Chrome (version 88 and above). Support for Microsoft Edge, Brave, and Firefox is planned for future releases

Search for 'FactChecker Pro' in the Chrome Web Store and click 'Add to Chrome'. The extension installs in seconds with no additional configuration required.

You can use basic credibility scoring without an account. However, creating a free account unlocks your personal Transparency Score, claim submission history, badges, and leaderboard access.

Click the FactChecker Pro icon in your browser toolbar, then click 'Sign In / Register'. Enter a username, email address, and password. Your account is created instantly.

The extension works on any publicly accessible webpage including news sites, social media platforms, blogs, and online publications.

The extension scans the visible text of the page you are viewing and identifies statements that can be verified — such as statistical claims, quotes attributed to public figures, and factual assertions. These are highlighted for your review.

A Credibility Score is a numerical rating (0-100) assigned to a source based on factors including its accuracy history, known bias indicators, and fact-check records from independent verification organisations.

Your personal Transparency Score reflects your fact-checking activity and accuracy over time. It increases when you submit claims that are verified as accurate and decreases when submissions are found to be incorrect.

Highlight any text on a webpage, right-click, and select 'Submit to FactChecker Pro'. Alternatively, open the extension panel and use the Submit Claim feature from the dashboard.
