Ghost doesn't ask you to trust it — it proves everything. Every AI decision generates a signed, hash-chained proof record in a tamper-evident AI Evidence Log. The 7-layer architecture (Proof, Safety, Policy, Runtime, Memory, Routing, Observability) runs entirely on-device with a 4-tier model system. Deterministic replay reproduces any AI decision exactly. Fleet attestation with drift detection serves enterprise compliance. The moat isn't offline AI — it's proof of AI behavior. Ghost occupies a category no cloud-first competitor can enter.
The Challenge
You can't verify what model processed your data. You can't prove your data stayed private. You can't reproduce a decision for an audit. You're asked to trust — with no way to verify.
Opaque AI decisions — no way to inspect which model or policy produced a response
No reproducibility — ask the same question tomorrow, get a different answer
Data leaves your control — every interaction sent to remote servers
No audit trail — API logs are not cryptographic proof
How It Works
Our proven process delivers production-grade results at every stage.
Install Ghost and download the 2.4GB model pack once with Ed25519 signature verification.
Ghost generates an Ed25519 signing keypair. Private key in Secure Enclave, public key exportable for verification.
Every AI decision generates a signed, hash-chained proof record. Inspect via the Proof Drawer (Simple/Advanced/Paranoid).
Export signed JSON proof bundles. Anyone with your public key can verify origin, chain integrity, and content authenticity.
Capabilities
Tamper-evident, hash-chained, device-signed proof records for every AI decision. SHA-256 chain integrity.
Reproduce any AI decision exactly: same input, model, context, seed = identical output, cryptographically verified.
7-layer architecture with 4-tier model system. Zero data leaves your device. Cryptographic proof of locality.
Declarative enforcement with cryptographic proof of compliance. RBAC, retention policies, cloud escalation rules — all auditable.
Drift detection, quarantine, compliance snapshots, model registry attestation against approved hashes.
MCP, A2A, ANP, AG-UI, AGORA, LMOS, AP2, OASF — every protocol interaction logged to the Evidence Log.

FAQ
A tamper-evident, device-signed record chain. Each proof record contains model provenance, context fingerprint (SHA-256), processing locality, memory references, policy constraints, quality events, timing, device attestation, digital signature (Secure Enclave), and chain integrity hash.
Reproduce any AI decision exactly: same input, model, context, seed = identical output, cryptographically verified. Model archive with immutable hash registry (3-7+ year retention). Legally defensible for healthcare, legal, finance, and defense.
Yes, 100%. After the initial 2.4GB model download, Ghost never requires internet. All 23 languages work offline. Cloud escalation is optional and explicitly logged to the Evidence Log with proof records.
