Paste a citation and the AI statement that relies on it. Verity checks whether the authority exists, remains good law, and supports the way it is used.
Verity is the atomic verification workflow inside VariLegal. It independently retrieves the authority and evaluates whether the AI-assisted use is supported by the legal record.
Verity resolves the citation, verifies the case identity, and retrieves the authority record from an independent source.
Verity checks treatment status and whether the cited authority supports the proposition for which it is used.
The deterministic auditor judges consequence and produces an evidence-backed verification certificate.
