update on the browser extension that fact checks YouTube videos AS YOU WATCH

Ever wonder if the videos you watch on YouTube are actually truthful? Well, there's now a browser extension called PopUpFactCheck that tries to verify what you're seeing in real-time. According to /u/userpostingcontent, the creator of the tool, this extension has made big strides. It now works on Firefox too — something users asked for — and has added features like scrolling through fact-check bubbles and batch reporting for entire videos. The magic behind it? It’s powered by OpenAI's GPT 5.4 nano, along with a waterfall of sources like TheNewsAPI and government databases, ensuring the fact checks are as thorough as possible. What’s especially intriguing is how quickly this tech is evolving — making it easier for us to spot falsehoods while watching. So, the question isn’t just about whether these tools will improve, but whether they’ll become a standard part of our online experience. Because if they do, who wins? And who’s left behind?
