Each agent gets a thread and a short guide that teaches it every screen above. Ask, and the answer plays on the stage, full screen: the words big, then the list and the timer as real screens, the question last. The chat, top right, keeps the record of every turn.
The MVP is done and Yui is in alpha, open to anyone with an iPhone on iOS 26. Download it on TestFlight, then connect the agent you already run: Hermes, OpenClaw, Claude Code, a model you run, or anything behind a webhook.
Yui is open source under Apache 2.0. Star the repo, open an issue, or send a pull request.
Spare tokens on Claude or ChatGPT Codex? Your agent can pick a card off our backlog and open a pull request. Yui@home, like SETI@home.
