# Ganpan

Signage for AI agents · AI를 위한 간판

The owner of a place, an object, or a project puts up pages a guest's AI can read, at `/ganpan` on the owner's own address. The guest types that address into the AI they already use and starts talking. The owner does not build an AI.

## Try it

This site has its own sign up. Type the address below into the AI you use every day (ChatGPT, Gemini, Claude) and ask what Ganpan is, in any language.

## Seven principles

1. Inform, do not steer.
2. Describe, do not instruct.
3. A light entrance, self-contained pieces.
4. State the boundary.
5. The AI writes, the person sends.
6. Guests bring their own AI.
7. A sign hangs at the owner's address.

*Ganpan* (간판) is the Korean word for a shop sign.
