Free Fact Checker is a powerful Chrome extension designed to enhance the accuracy of information consumed online. It allows users to instantly fact-check any text from AI chats, social media, or news articles by leveraging Google Search. This tool is particularly beneficial for individuals who frequently engage with AI-generated content, journalists, researchers, and anyone seeking to verify the authenticity of information before sharing or acting upon it. The process is straightforward: users highlight the text they wish to verify, and the extension sends this text to Google Gemini, which retrieves real data through a method known as grounding. The results are presented with citations and sources, ensuring that users receive factual information rather than AI-generated opinions. The Free Fact Checker works seamlessly across various platforms, including ChatGPT, Gemini, Claude, and popular social media sites like Facebook, X (formerly Twitter), and Reddit. With a freemium pricing model, users can make up to 20 grounding requests per day using a free API key from Google, making it accessible for casual users and professionals alike. The extension does not require any login, ensuring user privacy and ease of use. Additionally, it does not track user queries, providing a straightforward and secure fact-checking experience.
