While your agent works, the stage shows its mark breathing and one line under it: On its way until it picks your message up, then a working word and the time, like Figuring it out · 7s. The word changes every few seconds. The chat shows the same line in one row, and it goes when the answer lands.
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.
