The public TestFlight beta is open to anyone. This form is the other way in: for people with no agent yet, who want help connecting one, or who want the invite by email. Your name, the email on your Apple ID and a phone number; Apple emails the TestFlight invite.
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.
