# Introduction

> SINT Labs is an AI research and engineering lab building the governance layer for autonomous systems.

## What SINT Labs builds

SINT Labs is an AI research and engineering lab. We work on the layer between an agent's decision and its physical, financial, or irreversible consequence. Three divisions, one lab.

<CardGroup cols={3}>
  <Card title="Protocol" icon="shield" href="/protocol/overview">
    SINT Protocol — the open-source governance standard for autonomous systems. Capability tokens, policy gateway, evidence ledger, twelve transport bridges.
  </Card>

  <Card title="Products" icon="cube" href="/products/overview">
    Console, Avatars, Operators, CMO Operator — unified by SINT OS. All governed by the Protocol.
  </Card>

  <Card title="Studio" icon="briefcase" href="https://sint.gg/studio">
    Custom builds, enterprise deployments, dev shop. We deploy the stack for companies who need the outcome.
  </Card>
</CardGroup>

## The problem we work on

Model-level alignment is not a safety invariant. The same natural-language command issued to four frontier models on the same robot produces up to a 4.8× spread in out-of-policy attempts. The same MCP tool description, poisoned, yields arbitrary code execution on the client. The same robot platform, shipped with hardcoded keys, yields wormable BLE takeover.

The authorization layer for autonomous systems is missing. We're building it.

## Start here

  <Card title="Quickstart" icon="rocket" href="/quickstart">
    Run SINT Protocol locally in under five minutes. Docker Compose spins up the gateway, dashboard, Postgres, and Redis.

  <Card title="Architecture" icon="sitemap" href="/architecture">
    How Protocol, SINT OS, OpenClaw, Avatar, and the products compose into a unified runtime.
  </Card>

  <Card title="Whitepaper" icon="file-lines" href="/protocol/whitepaper">
    The formal specification — DFA, tier function, CSML, threat model, compliance mappings, and bibliography.
  </Card>

  <Card title="Protocol spec" icon="book" href="/protocol/spec">
    The normative specification for anyone implementing SINT from scratch.
  </Card>

## Open source, open specification

Everything below the product line is open and public.

  **SINT has refocused.** This site documents the SINT Protocol, SINT OS, and SINT Labs' products. Earlier Web3 and consumer-agent work (2024–2025) is archived at [/archive](/archive/notice). Nothing is being sunset — existing commitments stand.
