PopUp Fact Check for YouTube por PopUpFactCheck

PopUp Fact Check adds real-time fact-checking to YouTube videos. As you watch, the extension analyzes claims made in the video against authoritative sources and surfaces the results as color-coded bubbles overlaid on the video — green for true, red for false, yellow for misleading, and more. No setup required — just turn on closed captions and watch.

WHO IT'S FOR

If you watch political speeches, debates, press briefings, news clips, or campaign coverage on YouTube and want to know which claims check out, which are misleading, and which are flat-out false — without opening five tabs and running your own searches — this extension does that for you automatically while the video plays. Useful for anyone trying to cut through misinformation and spin in real time.

HOW IT WORKS

The extension reads the captions as the video plays, identifies fact-checkable claims, runs them against a tiered stack of sources, and returns a verdict as a small bubble in the video player. Each bubble shows the verdict, a short summary explaining why, and a link to the primary source so you can verify for yourself. Bubbles appear in sync with the speaker, so you see the check next to the claim that triggered it. No pausing, no second screen, no manual searching.

WHAT GETS FACT-CHECKED

• Political speeches and rallies
• Presidential and congressional press briefings
• Debates, town halls, and interviews
• Campaign ads and news analysis
• Economic and policy claims (inflation, unemployment, GDP, legislation)
• Historical, legal, and judicial claims
• Election results and voting procedure claims
• Breaking news

WHAT DOESN'T GET FACT-CHECKED

Clear opinion, rhetoric, and hyperbole are flagged as OPINION rather than pretended-verified. Predictions about the future, value statements, and purely subjective assessments are treated the same way. The goal is an honest verdict on factual claims, not a verdict machine that rubber-stamps everything.

SOURCES
- Wire services: Associated Press (AP), Reuters
- Government data: Bureau of Labor Statistics (BLS), Federal Reserve Economic Data (FRED)
- Fact-checkers: PolitiFact, Snopes, and others via the Google Fact Check API
- Trusted news outlets for breaking and current events
- Primary documents where appropriate

The extension prefers structurally-independent sources — wire cooperatives, non-profits, named experts — over outlets with editorial agendas, regardless of political lean.

FREE AND PAID
The free tier is generous — most casual viewers never hit the daily limit. Heavy political-content watchers can upgrade for higher limits.

PRIVACY
The extension only activates on YouTube. It reads video captions and metadata to identify claims. No personal data is sold. Sign-in is optional and only used for higher-tier limits if you choose to upgrade.

ABOUT
PopUp Fact Check is built by a small independent team. It exists because assuming that a claim made on camera by a public figure has already been checked by someone, somewhere, is no longer a safe assumption. If you want verification in real time, this puts it in the video player where the claim was made.
