In law, a flag is an opinion. A certificate is evidence.

What does typical legal AI leave you with?

The market is full of capable drafting and research tools, and this page is not an attack on any of them. But structurally, most share the same posture: hallucination risk is managed by grounding and hope; confidentiality is managed by zero-retention contracts; accountability is managed by internal logs. Every one of those is a claim someone must take on trust. Peer-reviewed research found leading legal AI research tools still answer incorrectly on a meaningful share of queries — which is why the checkpoint matters more than the model.

What does verifiable add?

• Citation integrity you can prove — every authority resolved for existence, quotation, and good-law standing, with a certificate rather than a dashboard flag.
• Privilege isolation you can prove — a signed attestation that privileged material never reached a third-party model in retrievable form, bound to informed consent.
• Records that survive skepticism — post-quantum signatures and an RFC 6962 tamper-evident log, so the proof outlives both the vendor relationship and the cryptographic transition.

The honest boundary

Verifiability is not a promise of perfection. RankShield does not claim an AI that never hallucinates; it certifies which of your citations are real, accurately quoted, and good law. It does not guarantee privilege is preserved; it attests the isolation architecture and consent. It is quantum-safe, not quantum-proof. The entire premise is that in a profession built on evidence, your AI accountability should be evidence too.

Frequently asked questions

Why not just trust vendor logs?

Because logs a vendor controls prove very little when something goes wrong. Standard logs can be edited, retconned, or simply never written, and the party relying on them must trust the party who kept them. An append-only, hash-chained record verified by outsiders removes that dependency — the difference between “we logged it” and evidence.

Who can verify a RankShield receipt?

Anyone with the receipt: your firm, your client, a court, an insurer, or opposing counsel. Verification checks the post-quantum signature and the inclusion proof against the transparency log, and requires no account with us and no access to your systems. Independence is the point.

Is 'verifiable' just marketing language?

It is the one claim we make that you can test. Every certificate and attestation carries a signature and an inclusion proof designed to be checked by third parties. If a claim can't be checked, we don't lead with it — that is the working definition of the honesty doctrine this product is built around.
