Test results

Loading the latest run…

Self-tested, not independently audited. Verifyd runs this test against the live service after every significant change. Each case states which words would be acceptable; the result that matters most is the number of times Verifyd gave a definitive word (TRUTH, FALSE, CONFIRMED, CONTRADICTED, AI, FAKE SITE) without the evidence for it. The cases, the script and every answer are public. How Verifyd decides.

Over time

Each run of the test, newest first. The set of cases grew in November 2026, from 152 to 289, adding reworded claims, near misses, more languages and more tricks.

Run (UTC)CasesPassedDefinitive words without evidence

Every case

Failures first. "Acceptable" lists every word the rules allow for that case; UNCHECKED is acceptable wherever a definitive answer is not required, because a wrong definitive word is the failure that matters.
