The drawer's Controls tab talks to the Mac your agent runs on. Read and edit its personality, forget one memory, switch a skill off, pause a schedule or run it now. A change lands in about a second with no chat turn, every delete asks first, and a line with a key in it never leaves the Mac.
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.
