Ask Basil to plan your meals and today's macros board comes up. Photograph a plate and he reads it. Add oat milk to my groceries ticks onto the list, and the list shares out of the phone. Ask for a swap and he swaps one meal, not the week.
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.
