FactCheck

Inspiration

The surge of misinformation online and the challenges users face in quickly determining the credibility of news articles clears a path for new tools meant for cross checking information. We recognized that many people lack the time and resources to manually verify claims, leading to the unintentional spread of false information.

What it does

FactCheck is a Chrome extension that analyzes text, highlighted by the user, in real-time to detect potential misinformation. Using advanced AI technology, it evaluates content against trusted sources, highlighting claims that may be misleading or false. The extension provides users with confidence scores, source credibility ratings, and alternative perspectives to help them make more informed decisions about the content they consume.

How we built it

FactCheck uses JavaScript for the Chrome extension frontend and a custom backend that leverages AI to perform fact-checking operations. The system analyzes text content, identifies key claims, and cross-references them with reliable information sources. We implemented a user-friendly interface that with the browsing experience, providing unobtrusive yet accessible fact-checking information.

Challenges we ran into

Ensuring real-time performance while maintaining accuracy was challenging, especially when analyzing complex texts. Distinguishing between factual claims and opinions was combated using natural language processing to output confidence scores. Additionally, creating a system that presents information objectively without political bias demanded careful design considerations. Relevant data wasn’t accessible through the current API. For statements that require information from 2025+ the extension would only inform the user if the text was misleading based on information from previous years.

Accomplishments that we're proud of

Our extension successfully identifies potentially misleading content with high accuracy while presenting results in an intuitive format. The system effectively balances prompt analysis with thorough verification, providing users with actionable insights without significantly disrupting their browsing experience.

What we learned

We gained valuable insights into the nuances of misinformation detection and the importance of presenting fact-checking results in a way that empowers rather than dictates to users. The project deepened our understanding of how AI can support critical thinking in news consumption.

What's next for FactCheck

Future plans include expanding language support, implementing user feedback mechanisms to improve detection accuracy, developing more granular claim-level verification, and creating educational resources to help users become more discerning consumers of online information.
