Timed on a phone-sized screen with a slow connection. A page that loads 107 KB less script, and a repeat visit that draws your last chat in 0.45 s instead of 2 s. A first visit is still about 4 s, because it has nothing kept yet.
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.
