Your AI acts.
Sannvit answers for it.
The true witness to what your AI did. The Sannvit Ledger seals every consequential AI action into a court-grade¹, tamper-resistant chain of custody — inside your own walls. When a regulator, insurer, or opposing counsel asks what happened, you don't argue. You open the record.

Logs are what your engineers kept. Evidence is what a court accepts.
AI agents now draft the client letter, screen the portfolio, file the claim. When one of those actions is questioned, the only account of what happened is a log the machine wrote about itself, in a system your own engineers can edit. Observability answers "is it working?" Compliance asks a different question: prove what it did.
What observability keeps
- Rows an administrator can edit — a claim, not evidence
- Retention measured in days or weeks
- No distinction between what the AI asserted and what was independently recorded
- Events without custody — no chain from decision to what it relied on
What an examiner, court, or insurer needs
- Sealed records even a privileged insider cannot silently rewrite
- Retention in years — with lawful destruction that leaves proof
- Every sealed field names its witness — "says who?" is already answered
- The full chain of custody: what it did, what it relied on, who signed off
Capture. Seal. Answer.
1 · Capture
A lightweight SDK observes your AI's actions without intermediating them — nothing sits between you and your model provider, and the Ledger cannot take your systems down. Native OpenTelemetry intake turns instrumentation you already have into evidence.
2 · Seal
Each action becomes a chained, cryptographically sealed record in a two-plane ledger — queryable plane and independent append-only plane, continuously cross-checked, externally anchored to court-grade time. Tamper-resistant, not merely tamper-evident.
3 · Answer
A dashboard built for the compliance officer reconstructs any decision's chain of custody and exports the regulator-ready record. docker compose up in your own VPC or on-prem.
Chain of custody, not log files
Every consequential action normalized into a regulator-ready record — the action, what it relied on, the output, who signed off — sealed in sequence.
Replay — see what the AI saw
Every retrieval recorded with source, timestamp, and a content fingerprint that pins the version. If the document changes tomorrow, the record still proves what was read today.
Delete the data. Keep the proof.
Content lives behind fingerprints — erasure genuinely destroys it while the unbroken chain still proves what existed, when, and what it was.
Even looking is evidenced
Opening evidence seals an access record into the same chain before the content is served. Enforced in the database, not by policy documents.
The ledger that audits itself
Integrity checks run continuously and self-record into the sealed chain. Turn vigilance off, and the gap in its timeline is itself evidence.
From forensic to preventive
The same capture layer that proves what happened will enforce policy — observe first, enforce when ready. Behavioral baselines ride the same sealed stream.
Don't take our word for it. Take the record's.
We publish a sample chain of custody — real record structure, ungated — and we invite you to tamper with it. Edit any field and watch the chain catch you, live, in your browser.
Open the record — and try to break itOne price, published. One demonstration, live.
$40,000 a year, flat, self-hosted, everything included — published on principle. And a thirty-minute demonstration where we alter a sealed record in front of you and let the ledger answer.
Book the demonstration¹ Court-grade means built to the standards courts use to authenticate machine-generated records: every record carries a verifiable hash chain (RFC 8785 canonicalization + SHA-256), independent trusted timestamps (RFC 3161), and a named witness for every sealed field — the authentication pattern of Federal Rules of Evidence 902(13) and 902(14). We build the record so you don't have to argue for it.
