Claimek — Catch shaky claims while you watch

Field notes

The extension separates detection from interruption: it reads existing YouTube captions, filters for factual claims, and suppresses levels 1 and 2 before anything reaches the browser. Its five-level system exposes only “some doubt” through “strongest doubt,” while a displayed example pairs a 97% confidence figure with a VERA Files source. The page also states that videos without captions cannot be analyzed, making caption availability a concrete operating constraint.
