Second Opinion

Second Opinion is a Chrome fact-checking extension that highlights text and calls Grok for AI analysis when browsing the web, social media, and news, helping you check accuracy, compare opinions, and identify bias and misinformation. It is free to install and use, but you need to bring your own Grok API key for analysis, making it suitable for people who often read and research materials online. It is suitable for easy verification when reading, rather than leading all articles into a background for slow analysis. For people who read news, social media, and blogs, it can turn "doubt before check" into a browsing action. It is suitable for turning "a glance first" into a browsing habit of "highlighting first and then continuing", reducing being biased by a single statement.

Second Opinion is not a regular chat page, but a fact-checking tool embedded in the browser. When you see a suspicious piece of content on a web page, social media, or news, you can highlight it directly and let it give you a second perspective analysis.
