Live · v0.6.0 · 104 services governed

Govern every AI decision.
The AI decides. You consent.

StoneAI is the approval brake for autonomous systems. A council of models deliberates, issues a reasoned decree, and changes nothing without your explicit signature — recorded forever in a hash-chained ledger.

How it works

Four steps. One unbypassable gate.

Every governed action flows through the same path. The gate is enforced by construction, not by policy.

📖
01 · TRUTH

Observe

Live fleet & signal telemetry feeds the council with verifiable ground truth.

⚖️
02 · COUNCIL

Deliberate

Multiple models reason together, resilient to any single provider failing.

👑
03 · DECREE

Recommend

An inert, content-hashed recommendation with reasoning and confidence — it carries no power.

🙏
04 · COVENANT

Consent

A human signs approve or deny, cryptographically bound to the decree. Only then can the customer act.
