TruthArc is a Chrome extension designed to help users critically analyze their news consumption. By monitoring the political bias of news articles and videos, it provides insights into the media landscape. The tool automatically tracks content from popular news sources and pre-selected YouTube channels, enabling users to see the spectrum of political viewpoints they are engaging with.

The extension employs a language model-based algorithm to analyze the scripts of articles and videos, categorizing them as liberal, conservative, or centrist, and presenting this information with concise reasoning. Users can access a personal dashboard that summarizes their reading habits, including the number of articles consumed and the distribution of political bias, promoting a more balanced perspective in media consumption.
