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 hands that address to the AI they already use and starts talking. The owner does not build an AI.

Status: draft v0.1. Not yet validated in the field.

Try it

Give the address below to the AI you use every day (ChatGPT, Gemini, Claude, and so on) and ask it what Ganpan is. In any language. This site has its own sign up.

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.
