PolyLens is a free Chrome add-on designed to provide users with a multifaceted analysis of text bias. By highlighting any text on a webpage, users can access insights from four independent AI models, each offering a unique perspective. The tool generates a Bias Divergence Score, which ranges from 1 to 10, and breaks down the analysis across six key dimensions: political framing, social perspective, safety filtering, omission detection, emotional framing, and source authority. This functionality allows users to see how different AIs interpret the same text, highlighting potential biases in the information presented.

The user experience is straightforward and efficient. After highlighting the desired text, users can simply right-click and select the PolyLens option or use the keyboard shortcut. Within 15 to 30 seconds, the analysis appears in an overlay panel, making it easy to review the findings without navigating away from the current webpage. This tool is applicable across various online platforms, including articles, forums, and social media, ensuring that users can critically assess the information they consume.
