We built DeepVerify because we kept doing the same thing: pausing a video,
opening a new tab, typing in a claim that sounded off, and giving up halfway
through the search results.
Checking something takes more effort than hearing it does. That gap is part of
why bad information travels so easily.
So DeepVerify does the checking in place. It reads the captions or the page,
pulls out the claims that can actually be verified, and puts a verdict next to
each one with the sources attached.
One deliberate choice: it is allowed to say "Uncertain." Always returning
true or false would look more impressive, but a fact-checker that is
confidently wrong is worse than none at all. When the evidence isn't there,
it says so.
Two things we'd genuinely like feedback on:
Where does it get things wrong? Send us the video or article and we'll dig in.
Is a sidebar the right place for this, or does it get in the way?
Free to install. Works on YouTube, articles, and live audio.
