| Where it works | Any video or audio link — YouTube, TikTok, Instagram Reels, podcasts — plus a Chrome/Firefox extension that runs while you watch. | Facebook, Instagram and Threads only. It's built into Meta's apps and doesn't reach content hosted anywhere else. |
| Availability in the US (2026) | Fully available in the US on the free tier. | Meta ended the US third-party program in April 2025 and replaced it with Community Notes. The professional program still runs outside the US, with partner contracts renewed for 2026. |
| Who actually does the checking | AI transcription and claim extraction cross-referenced against live web sources. Fast and tireless, but it's a machine, and it can be wrong. | IFCN- or EFCSN-certified journalists doing original reporting against primary sources, published as a citable article under their own byline. |
| Can you request a check? | Yes — paste any link and get results in minutes. That's the entire product. | No. Meta's systems surface candidates by sharing velocity and keyword signals; fact-checkers prioritize viral hoaxes under monthly volume caps. Politicians' speech and opinion content are exempt. |
| Detail on a long video or podcast | Every verifiable claim scored 0-100 individually with linked evidence, plus logical-fallacy and AI-generated-media flags. | One rating for the whole post, drawn from a six-point scale: False, Altered, Partly False, Missing Context, Satire, True. |
| Power to limit a hoax's spread | None. It tells you what's true. It cannot touch distribution anywhere. | Real enforcement: False and Altered content gets sharply reduced distribution, loses recommendations and ad eligibility, and repeat offenders face demonetization. |
