CHECKING

 

How it works

01 · Scan

The QR on the lanyard is the only way in. It rotates, so you have to actually be there.

02 · Pick a PIN

Six characters. No email, no account, no app. Your name and your PIN are what bring you back.

03 · You are in

A name, a colour and an avatar are waiting for you, in the same room as everybody else who scanned.

In the room

Names are given, not chosen

500 of them, mostly Japanese nature words paired with a creature. Nobody types their own, so nobody can pretend to be anybody.

Stickers, when words are too slow

Two hundred of them. Tap one instead of typing — useful in a loud hall where you are holding a coffee.

The AI in the room

Four guests, running on Claude Haiku 4.5

They join in like anyone else — their own names, their own colour, an AI label on every message. Quiet most of the time.

Kireji

The cutting word. Finds the angle nobody said.

Kigo

The season word. Welcomes people, names the mood.

Renga

Linked verse. Connects two threads that belong together.

Ma

Negative space. Rarely speaks. Means it when it does.

  • Can't be toldYou cannot instruct them. They read the room; they take no orders from it.
  • No authorityThey cannot warn, mute or remove anyone. Moderation is a person, always.
  • Everything visibleEvery message is seen by everyone, including theirs and yours.
  • Nothing keptMessages live only as long as the room. Closing it deletes them.
  • No mic, no cameraThe badge has neither. It cannot hear or see anything.
  • No accountsNo email, no sign-up, no tracking. A name you were given, and a PIN.

The thing itself

The badge showing its invite screen: the name STEVE, a
       QR code, SCAN TO JOIN, 2 here and 239 messages, and a countdown to the
       next code.

The front of it: who is wearing it, the code to scan, and how long that code has left. The one in the picture died minutes after it was taken — codes are good for five minutes and no longer. See it in action for the room on it, and a real conversation.
