Facty

Real-time AI fact-checking for YouTube videos — verified claims, clear verdicts, and sources, in any language.

Facty fact-checks YouTube videos as you watch — no setup, no API keys. HOW IT WORKS Facty reads the video's subtitles, extracts the checkable claims, and verifies each one with AI plus live web search. Verdicts appear right on the video as you watch, and a full report is available in the side panel. WHAT YOU GET • Live verdicts on a 5-level scale (true → false), shown as cards over the player • Every verdict backed by real sources you can open and check yourself • A claim-by-claim report for the whole video, with timestamps you can jump to • Works in any language — the video's language doesn't need to match yours • Free to start, no account required for a quick check WHO IT'S FOR News and politics viewers who want a second opinion, traders and investors who can't afford to act on bad information, and researchers who need a quick claim-by-claim breakdown of a video. Facty runs quietly in the corner of the player — click the pill icon any time to open the full report, and use the popup to manage your account, language, and plan.
