## Description

Ever wonder if a viral YouTube video is actually true? FactScope tells you in one click.  Your first 2 checks are free, no sign-up needed.

Click the FactScope icon on any YouTube video and a side panel slides in with the URL pre-filled — just press Analyze. You'll also see an inline FactScope badge right under the video title: if the video was checked before, the verdict shows instantly and for free.

The AI reads the video's transcript, extracts the key factual claims, cross-checks them against live web search, and returns:
• A clear verdict — Real, Fake, Mixed, or Story
• A confidence percentage
• Plain-English reasoning
• The specific claims it flagged
• The sources it used

Your first 2 checks are free with no sign-up. After that you can grab credits on the web app — repeat checks of the same video are always free.

Not affiliated with YouTube or Google. FactScope uses AI and can be wrong — always verify important claims yourself.
