01 The World OS Khan Engine · v0.8.0

Khan Engine

An AI-native World OS for simulated interactive worlds — an embodied AI runtime that looks like a game engine.

01Intent

Intent

LLM gives intent. The agent proposes through typed intents; proposals may be wrong — that is fine.

02Truth

Truth

Engine gives truth. Validation runs deterministic, contract-checked simulation. Proposals either survive or are rejected.

03Control

Control

Editor gives human control. Branch and merge for multi-agent worlds. No session context → no mutation.

04Trust

Trust

Evidence gives trust. Proven, reproducible, rollback-able evidence. Nothing is believed on faith.

What we build

Each project lives on its own page — status, stack, and a world of its own. This page is itself a project, world #0.

Itrains

early idea

A rainy world under simulation — mysticism, weather, and care. Itrains stays poetry; Khan Engine stays engineering.

03 Agents & Simulation Specimen 0000

Citizens, not guests

Agents live inside verifiable physics and scenarios — not in loose text. Each has identity, capabilities, a budget, and an audit trail.

  • 01 Determinism Same seed, same world, every time. Reproducible by default.
  • 02 Observable Evidence Nothing is believed on faith. Proof travels with the change.
  • 03 Agent Citizenship Identity, capabilities, budget, audit — not a tool call.
  • 04 Semantic Interfaces Agents see meaning, not pixels. Worlds expose their own intent.

The Semantic Mirror gives them sight; the Agent Session gives them citizenship: no session context, no mutation.

Itrains — a world under simulation; poetry, weather, and care.

What this is not

The negative space is part of the design: what we refuse to add defines the system as much as what we ship.

  • 01 No token. no chain, no ticker
  • 02 No analytics. no third-party scripts
  • 03 No mobile app. the web is the app
  • 04 No build step. open the file
  • 05 No network at load. zero external requests
