Anyone can provide an answer.

H33 provides independently verifiable evidence for why the answer was produced.

Verifiable Enterprise Search builds attested answers whose authority, policy, pipeline, corpus, model, evidence, citation, and replayability can all be independently verified — without contacting H33.

H33 was not contacted during this verification.

When your verifier produces a verdict on a VES bundle, no H33 endpoint participates. The verifier binary is open source. The conformance vectors are published. The cryptographic primitives are standard. The bundle's portability is the product.

What happens if H33 disappears? Verification still succeeds. → Read the answer.

One screen. Six questions. Six checkmarks.

A buyer, regulator, auditor, or carrier never asks for "EC-3 verdict" or "EC-8 verdict." They ask the six questions on the card. The card answers them. The substrate underneath is the engine; the card is the product.

Same bundle. Two independent verification paths. Same result.

Where verifiable enterprise search matters

Insurance & Carrier Risk

Decision Insurance verticals require provenance for every claim evaluation. The bundle is the underwriting record.

M&A Due Diligence

Acquirers need to verify that the target's documented decisions actually executed per the target's documented pipeline.

Regulatory Submission

Submit attested evidence to regulators without giving them a vendor-lock-in dependency. The bundle survives outside the originating system.

Audit & SOX Compliance

Audit-grade evidence chains for AI-driven decisions. Auditor questionnaire answers with cryptographic evidence references.

Federal / CNSA 2.0

Customer-held cryptographic keys. FIPS 140-3 Level 3+ HSM custody. No vendor-side key escrow.

AI Governance

When the EU AI Act's traceability requirements become operational, ship today against tomorrow's regulatory bar.

OpenAI retrieval helps you find information.

H33 helps you prove why information was returned.

Existing AI search and retrieval-augmented generation (RAG) stacks help your team find documents. They produce citations as references — pointers to source documents.

H33 builds the layer above. Citations as cryptographic bindings: proofs that the cited bytes in the source document support the claimed answer-span bytes, verifiable offline by anyone with the bundle and the verifier binary.

H33 wraps your existing RAG stack — Tantivy, Qdrant, FST, OpenAI, Anthropic, your own embeddings. The retrieval mechanics stay unchanged. The trust posture is fundamentally different.

How the verification stays independent

Open-source verifier

Apache 2.0. Reproducible build. Anyone audits it, anyone compiles it, anyone runs it.

Published conformance vectors

Input → expected canonical output → SHA3 digest. Independent implementations are conformant if and only if they produce byte-equal outputs.

Standard cryptography

NIST FIPS 204 (ML-DSA), FIPS 205 (SLH-DSA), RFC 8785 (JSON canonicalization). No proprietary cryptographic primitives.

Customer-held keys (Federal)

FIPS 140-3 Level 3+ HSM custody. Customer-side ceremony. H33 holds no Federal-customer signing keys.
