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.

Tested against the complete set of 225 overruled Supreme Court citations in the Stanford RegLab preregistered dataset. Built entirely on open-source CourtListener data. Three-stage waterfall enrichment. 0% false leniency is the sole pass/fail gate for model upgrades.
Verity ran as a hosted service. The same citation verification architecture is now delivered as infrastructure inside the customer's security boundary, where the agent being verified cannot reach the verifier.
