How the analyses work — our methodology →

Don't trust one AI — compare them

Every model has its own blind spots. Run the same article through several leading AIs and see where they agree and where they split — when models disagree, that disagreement is the signal: it shows exactly which claims are contested and worth a closer look.

Or pick Consensus from the model menu and let a panel of models from rival AI labs analyse the article independently and merge their verdicts into one result — with every model named.
