The problem with unverified AI reasoning

Circular reasoning is invisible at scale

AI models confidently produce arguments that assume what they set out to prove. Without formal verification, these slip through review undetected.

Malpractice exposure from AI-assisted work

Bar association guidance increasingly requires attorneys to take responsibility for AI outputs. A certificate of logical validity is defensible evidence of due diligence.

Discovery and privilege questions

Clients and opposing counsel want to know how AI was used. A Prova certificate is a machine-readable, tamper-evident audit record of every reasoning step.

How Prova solves it

1

Certificate-grade verification in seconds

Paste any AI reasoning chain. Prova extracts the argument graph, runs formal analysis, and issues a signed certificate of validity or a precise failure report.

2

Tamper-evident audit trail

Every certificate carries a SHA-256 identifier, dual version stamps, and is stored immutably. Forward it to clients or regulators with confidence.

3

Three failure types, precisely named

CIRCULAR, CONTRADICTION, and UNSUPPORTED_LEAP map directly to the reasoning defects courts and bar guidelines care about.

Prova turns "we used AI responsibly" from a talking point into a provable fact.
