  Stop wondering if what you just heard is true.
  
  WasThatTrue adds a Fact-check button to the YouTube player. Click it on a claim that sounds off, and the extension pulls the exact quote from the transcript, checks it against live web sources, and shows you the verdict in seconds. You never leave the video.
  
  How it works
  
  Watch any YouTube video with captions.
  Click the Fact-check button on the player.
  Pick the claim you want checked from a list of up to five.
  Read the verdict, with sources, dates, and a short explanation.
  Four verdict types, not two
  
  TRUE: the claim holds up against the evidence.
  FALSE: the claim contradicts what reliable sources say.
  CONTESTED: the evidence is mixed and the answer depends on context. You see the trade-offs, not a forced binary.
  UNVERIFIABLE: there's no primary source either way. You decide what to make of it.
  Most fact-checkers force every claim into True or False. Real life isn't always like that, and WasThatTrue says so.

  Privacy
  
  WasThatTrue only runs when you press the Fact-check button. It does not watch your YouTube activity in the background. Each fact-check leaves a short operational record (video ID, a one-way hash of the claim, timing) used for usage counting. The verdict text and raw claim are not stored. Full breakdown at wasthattrue.com/privacy.
  
  Limitations
  
  Desktop Chrome only.
  YouTube long-form videos only. Shorts are not supported in this version.
  Videos without captions cannot be fact-checked.
  Built for serious viewers who want to think for themselves.
