Footnote

Footnotes where it matters

* Footnote listens to what you watch. When a claim can be checked, it checks it, and shows you the sources.

Heard in the video2

“This is the house of Ukrainian President Zelensky. The mansion is worth 20 million dollars.”

  1. 1The phone shows a screen recording of Footnote on an iPhone, made in the Filming mode of the app. It shows the stored result of a real check. It is not a live run.
  2. 2The claim is from a TikTok video by @davejoneswoke. Lead Stories, USA TODAY, Reuters and France 24 published fact checks of it.
  3. 3Jev is a decision model on the Hostinger AI Router. The time is for one sentence.
  4. 4The 2 sentences that stop are examples, written for this page.
  5. 5The agent is our TypeScript harness on the Hostinger VPS. It uses GPT-6 Luna and web search through the Hostinger AI Router.
