Tamper-proof audit trails for every AI decision. Compliant with EU AI Act — and 12 more frameworks. One import. One function call. Evidence anyone can verify offline.
Generous free tier · No credit card required · Open standards, zero lock-in
Run an AI decision and watch Veratum generate a cryptographic receipt in real time.
No new databases. No infrastructure changes. One import, one function call, and every AI decision is covered.
Add two lines of code. Veratum intercepts every LLM call, captures the input, output, model, and metadata. PII is detected and redacted before anything leaves your infrastructure.
Each decision gets a cryptographic receipt: tamper-proof, independently timestamped, and verifiable by anyone. The receipt is added to an append-only transparency log that no one can alter.
When an auditor asks for proof, export your receipts. Each one is independently verifiable — no Veratum servers needed. Cryptographic proofs confirm nothing was deleted or modified.
A cryptographically signed compliance report — generated in seconds, verifiable forever.
Every AI decision, accounted for.

Cryptographic proof is a different category. Governance platforms help you write policies. Observability tools help you monitor models. Veratum gives you tamper-proof, independently verifiable evidence that holds up in court — and it works alongside your existing stack.
Here is what changes when you add Veratum to your stack.
EEOC · NYC LL144 · EU AI Act
CFPB · ECOA · Colorado
HIPAA · GDPR Art. 22 · MDR
NAIC · State Regulators
FINRA · SEC · MiFID II
Your jurisdictions · Your rules
One import. One function call. Works with any LLM provider. Your existing code stays exactly the same.
Our verification tools are open source and MIT-licensed. Verify any Veratum receipt offline, without our servers, without trusting us. Zero external dependencies.
No. Veratum adds a cryptographic evidence layer on top of your existing stack. Your logs stay in your logging system. Veratum creates receipts with hash chains, timestamps, and verifiable credentials so you can demonstrate to auditors that your records have not been modified.
Your AI keeps running. The SDK buffers receipts locally with a write-ahead log and syncs when connectivity returns. Every receipt can be verified offline without our servers. Our service is designed to be helpful but never a single point of failure.
Veratum uses open standards designed for evidentiary use: qualified timestamps (which carry legal presumption under eIDAS Article 41 in the EU) and W3C Verifiable Credentials. However, Veratum is infrastructure, not legal advice. Whether evidence meets a specific court's or regulator's standard depends on your jurisdiction and use case. We recommend consulting legal counsel.
Blockchains are designed for public consensus — they are slow, expensive, and expose data. Veratum gives you the same tamper-proof guarantees using proven cryptographic techniques, but keeps your data private, runs at API speed, and does not require public validation. Same trust guarantees, none of the overhead.
Enterprise plans include on-prem and VPC deployment options. Receipts use open standards, so you can always verify them independently — with or without Veratum infrastructure.
You are never cut off. We offer flexible overage handling so there are no surprises and no sudden service interruptions. Scale at your own pace.
We saw the same gap everywhere: companies shipping AI fast but having zero infrastructure to prove those decisions were compliant. Regulators are catching up. The EU AI Act has a deadline. US states are already enforcing. And most teams still have nothing to show when someone asks for the audit trail.
Veratum is the layer that fixes that — cryptographic evidence for every AI decision, built on open standards, designed so you never have to choose between moving fast and being ready for regulation.

Wrap any LLM call. No infrastructure changes. No new databases to manage.
PII never leaves your infrastructure. Client-side redaction with cryptographic commitments.
Industry-standard cryptography, verifiable credentials, and qualified timestamps. Every receipt verifies offline.
Pre-configured for EU AI Act, GDPR, NYC LL144, EEOC, CFPB, and more. Custom presets available.
Paste a receipt hash to verify it exists in a Veratum chain. No login needed — verification is public by design.
