What does Second Opinion do?
Second Opinion is a browser extension that lets you check the facts and spot bias in anything you read online. You highlight text on a webpage—like a news headline, a social media post, or a blog claim—right-click, and select the tool. It then uses AI to analyze that text, checking its accuracy, pointing out potential biases, and even offering alternative viewpoints. It's designed to be a quick reality check for the daily flood of information you encounter.
The tool works by connecting to the Grok AI model. You need your own Grok API key to use it, which means you only pay for the AI processing you actually use, with no subscription fee for the extension itself. It currently works on Chrome and other Chromium-based browsers like Brave and Edge, with plans to expand to Firefox and Safari. The analysis happens in seconds, giving you a concise summary of potential issues with the text you selected.
This tool is most useful for people who want to read more critically. If you're a student researching a topic, a professional verifying a claim, or just someone trying to navigate polarized news cycles, Second Opinion adds a layer of scrutiny. It helps you pause and consider the reliability of information before you accept it or share it further, making your browsing a bit more informed.
