What is PopUpFactCheck?
PopUpFactCheck is a browser extension and AI detector that brings fact-checking directly into YouTube while you watch. It listens to claims as speakers make them and detects if they are TRUE, FALSE, or MISLEADING. The verdicts are made in real time, with sources attached.
The tool works on any YouTube video: recorded interviews, news segments, political speeches, and live broadcasts. Anyone who wants to know what’s actually true while they’re watching can use it without doing separate fact-checking research afterward. You can get the extension for Chrome or Firefox.

Real-World Applications
Journalists and researchers covering fast-moving stories may find the live fact-checking and full-video report features especially useful. When a press secretary or politician makes claims during a live broadcast, the extension detects and flags them in real time. The exportable report gives writers a sourced reference to work from without replaying footage.
Educators and students who use YouTube as a learning resource can apply fact-checking to documentary content, expert interviews, or debate recordings. When a source makes a statistical or historical claim, a verdict with citations appears on screen. This gives students a starting point for verifying what they’re being taught.
Everyday viewers who follow political news or current events on YouTube may rely on the tool to keep up with what’s actually accurate during debates or speeches. Instead of pausing to search claims separately, they get verdict bubbles as the video plays. The non-partisan approach means the same standard applies whether they’re watching a candidate they support or oppose.
Podcast listeners and news consumers who watch long-form YouTube content can use the full-video scan to get a complete fact-checking breakdown in one pass. Rather than manually tracking disputed claims through a two-hour interview, the report surfaces every flagged statement with a verdict and source.
