The verification standard for AI.

Every AI action leaves a receipt anyone can re-check — offline, without an account, without trusting the system that produced it.

§ 01Platform

One substrate. Three packs. One receipt.

Portable proof of what an AI did. Open standard at the floor, paid packs above.

01 · Substrate

Apache 2.0 reference verifier.

Open at the floor. No lock-in at the base. Opens once its soundness checks pass.

02 · Standard

One bar. Systems certify against it.

The verifier is the standard. The standard is open. Nobody owns it.

03 · Receipt

Signed. Anchored. Replayable.

Every AI action emits a receipt. Anyone can replay the work.

§ 02Suite

One open floor. Three packs kept current.

Each pack is a reference the free verifier checks against — and each one drifts. We keep them current so your evidence never goes stale.

PACK 01
Conformance
EU AI Act evidence, mapped to Article 50 and each Annex, re-issued every quarter as the law drifts.
For · regulated AI teams
Flagship
PACK 02
Reference-Data
Ground-truth the verifier checks against — emission factors, ICD codes, jurisdictions — kept fresh.
For · data-bound outputs
In build
PACK 03
Model-Drift
Per-model attestation against each vendor's published model SHA, re-run monthly as new models ship.
For · model provenance

§ 03Landscape

Where we fit.

Governance flags it. Evals score it. Logs record it. Guardrails block it. We re-derive the result and hand you the proof.

§ 04Engagement

Open at the floor. Mandates at the ceiling.

Open substrate
Free, forever
The open verifier, free to run once the source opens. Any receipt, your own machine, no account. Works whether or not you ever pay us.
Pilot
$50,000
Drop the emit hook into one workflow. Receipts generate as you run — nothing leaves your environment. Your auditors can re-check every one.
Annual
Talk to us
Verification across your production workflows: SSO, audit logs, and an independent attestation option. Scope and price set in conversation.

The pilot fee is fixed and credits toward your annual on conversion. Annual scope and price are set in conversation.

§ 05Use cases

Built for the regulated enterprise.

Supply-chain integrity

The build-pipeline operator.

Signed receipts for every AI artifact in the pipeline. Conformance evidence on demand for SBOM and provenance auditors.

ConformanceModel-Drift
Creative IP at scale

The enterprise creative platform.

Every published asset rooted to a verified source, with a signed, re-derivable receipt. Built for agencies that ship at volume.

Reference-DataModel-Drift
Sector-regulated manufacturer

The chip, telecom, or device maker.

Conformance evidence on demand for the sector regulator, plus a signed receipt on every model output that ships inside the product.

ConformanceModel-Drift
Independent attestation

The audit-firm partner lane.

Recommendations rooted to the underlying evidence, with conformance the audit partner can re-derive and attest to independently.

ConformanceReference-Data
Model provenance

The frontier or sovereign model lab.

Every training source rooted to a verified origin, and a cryptographic stamp on every output that leaves the lab.

Model-DriftReference-Data
Sovereign verification

The public-sector procurement officer.

Conformance evidence the procurement officer hands to a deputy minister on one page, each claim backed by a signed receipt.

ConformanceReference-Data
Regulated finance

The bank or capital-markets desk.

A signed, re-derivable receipt behind every model-driven credit, fraud, or trading decision your model-risk team can re-check.

ConformanceModel-Drift
Clinical & life sciences

The health system or pharma lab.

Every clinical-AI output rooted to its evidence, with a signed receipt an auditor or regulator can re-derive on demand.

Reference-DataConformance
§ 06Trust

Open by floor. Defended at the edges.

The verifier is the standard. The standard is open.

Open at the floor

Apache 2.0 reference verifier. No proprietary base, no walled garden, no lock-in.

Public LICENSE drop the moment soundness checks pass.

Independently re-derivable

Re-run it yourself: a receipt re-derives byte for byte, or shows where it breaks. No account required.

An independent attestation option is available on every pack.
