The Living Ship.
A pirate adventure that shows what an AI OS is. The Oracle is the model. The ship is the harness. You build it, voyage by voyage.
Free, no account. Best on a computer with a keyboard.
A clever model is not a working system
The Northlight lighthouse has gone dark. Your ship has an untested AI mind, an old chart and a crew waiting for orders. Sail it, tell it what is true, connect its tools, and decide what it may do on its own.
The model can only talk
At the start the Oracle can reason and plan a route, but it cannot touch the wheel, and it only knows last season's chart.
The harness makes it useful
Tools, context, memory, checks and permissions are what turn a clever voice into a crew member you can trust with the ship.
You fit it piece by piece
Twelve upgrades across six voyages. Each one is a layer of a real AI system, and each card says what it means in real life.

Common questions
- What is The Living Ship?
- A free browser game by Jason Q. Lu about how AI systems are built. You captain a ship whose AI mind, the Oracle, starts with only a voice. Over six voyages you give it tools, context, memory, checks and permissions, and see why each one matters.
- Does the game use a real AI?
- No. The Oracle and the crew are scripted, and the game does not call an AI model while you play. Their voices were recorded in advance with an open text-to-speech model. It teaches how AI systems are put together, not how to use one.
- Is it free, and do I need an account?
- It is free and needs no account. Your progress saves in the browser you play in.
- What do I need to play?
- A computer with a keyboard, and sound on if you can. It is built for a keyboard and plays best there. The first load downloads the ship, the islands and the crew.
