Second Opinion

Second Opinion turns fact-checking into a right-click action. Instead of opening a new tab, pasting a claim into a chatbot, and rewording your question, you highlight text on a news article, social post, or research page and select "Get Second Opinion" from the context menu. The extension then returns a structured analysis in place, which keeps you inside the reading flow rather than breaking it.

The analysis is deliberately multi-angle. It checks accuracy of the specific claims, flags possible bias or loaded framing, and offers alternative perspectives so you can see how the same facts might be presented differently. The extension itself is free to install and use, and connects to Grok through your own API key, meaning you pay only for the token usage you actually generate rather than a subscription fee.

Because the output is generated by a language model, the developer is explicit that results should be cross-referenced with other reliable sources for high-stakes decisions. It is best understood as a fast first-pass sanity check that surfaces questions worth asking, not a final authority on what is true.
