A tiny anonymous chai web app built in one session

The virtual chai shop works without login or signup and is meant to stay free. Holding anywhere on the page makes the user sip chai, and the cup visibly drains while the steam fades.

When the cup becomes empty, it can be refilled and used again. Strangers can chat anonymously inside the experience.

The whole app was built in one session with Claude, using HTML, CSS, and in a single file. Small touches were added: the favicon changes as the cup drains, the tab title changes when the user switches away, and about one in six sips shows a rare message.
