Check whether a supplied public source supports or contradicts a factual claim. Validate citations in AI-generated answers against the supplied URL. TruthPal returns source-grounded evidence and a supported, contradicted, or uncertain verdict; when the source is insufficient, the result is uncertain. It assesses only the supplied source and does not independently corroborate the claim.
