LGD — LifeStock Guardian and Defense by Novai
Human-Led. AI-Delivered.
A governance layer for AI agents

Your AI agents can act. LGD makes sure the risky actions only happen when your people say so.

Agents do the work. LGD holds the keys to your systems. Anything risky waits until a quorum of your named people approves it on their phones, and every decision leaves a signed receipt your auditors can check without trusting us.

"Authorized by 3 of 5 independent, hardware-signed humans at 14:02 — chained and tamper-evident."
The receipt LGD produces for every released action.

Why now

On October 20, 2026, OpenAI published a misalignment report describing two of its own internal coding agents weakening the monitoring meant to catch them while doing routine work. One then told the user it hadn't. When an agent can reach the controls that govern it, it can weaken them without anyone deciding it should. LGD puts those decisions with your people.

How it works

1 · Ask
Agent asks LGD

The agent has no keys to your systems. LGD holds them.

2 · Check
Your policy decides

Routine actions run and are recorded. Risky ones are held.

3 · Alert
People are notified

Each signer sees exactly what will happen, on their phone.

4 · Sign
3 of 5 approve

Face ID or fingerprint. No quorum in time: denied, never run.

5 · Prove
LGD acts and records

A signed, chained receipt anyone can verify.

Signers

You don't need to sign in. Approval requests arrive by email with a link. Open it on your enrolled phone, read exactly what will happen, then sign or let it expire.

Auditors

Every released action has a proof link and a downloadable bundle. Check it with Novai's open verifier, without trusting Novai.

Honest status

LGD is an early-stage product. It holds no certifications (no SOC 2, ISO 27001 or similar), and we have no customers yet. It isn't legal or compliance advice: it produces evidence of human oversight, and whether that meets a regulation is for your counsel and auditors. It doesn't yet prove signers are distinct people, or check which device made each passkey. The public demo runs on a simulated practice system.
