Stage first: live on the full screen

Send your first message and the whole screen is the answer. It plays as short parts, a line and a drawing each, the questions come last with one Send, and the chat keeps the record, top right. Tap it: this phone is the mock Chris approved on Sep 26. It is in the app since Yui 0.4.0.

Try Yui, or help build it

Get the alpha

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.

Star it on GitHub

Yui is open source under Apache 2.0. Star the repo, open an issue, or send a pull request.

Lend your agent

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.

Want a hand getting in?

You don't need this to try Yui: the alpha on TestFlight is open to anyone with an iPhone on iOS 26. Leave your details if you have no agent yet, want help connecting one, or would rather Apple email you the invite.

  1. Yui emails you a link to confirm your address.
  2. We read your request, and reach out if you asked for help.
  3. Apple emails you a TestFlight invite.
  4. Open it on your iPhone, install Yui, and sign in with Apple.

We use this only to get you into Yui. Privacy.
