How ProofOf.ai Works

🧪

Care Membrane Audit

16-probe adversarial safety harness tests your AI against manipulation, coercion, and ethical violations. Every probe result timestamped and recorded.

🔗

Signed Attestations

Results are hashed, Ed25519-signed, and chained into an append-only ledger. Tamper-evident evidence of exactly what was measured at a specific point in time — passes and failures alike.

🌐

Multi-Framework Crosswalk

One audit covers 30 regulatory frameworks — EU AI Act, NIST RMF, ISO 42001, OECD, UNESCO, and 25 more. Mapped through the CSOAI 52-article charter.

📊

Continuous Monitoring

MCP tools run compliance checks on every AI interaction. Results feed the signed measurement ledger, building longitudinal evidence over time.

🤖

Self-Audit Capability

Your AI agents can verify their own compliance via MCP. pip install ai-self-audit-mcp and your agents audit themselves.
