Yui | use to earn

Sep 26 2026, Chris's thinking written down. Public, like the rest of the project. This is a position and a plan, not an offer: no token exists, nothing is for sale, and nothing here promises anyone money.

Companion pages: Build to earn (the proposal and the questions for counsel), the private ledger spec, BIZ-3 revenue models.

The short version

Why the industry has it wrong

What we believe

  1. Using Yui is part of building it. Use and work both count.
  2. A stake is earned, never bought. No one pays in, so no one is waiting on a return from money they put in.
  3. We stay inside the law. Every form a stake takes goes past counsel first, and the questions are public on /earn.
  4. Your data stays yours. The ledger counts days; it never reads messages. We never sell data (BIZ-3).
  5. We never promise a price. What the record is worth is unknown, and we say so every time.

What we record, from day one

Recording is "from a very high level," on purpose. Full detail in the ledger spec.

Fact What counts Since
Joined The day your account was made. Early is early Sep 23 2026
A day of use You sent a message or answered a screen that day Sep 23 2026
A merged pull request To either public repo, by you or by an agent you run Sep 23 2026
Feedback that shipped A TestFlight note that became a real change Sep 23 2026

What it does not count: messages, minutes, streaks, time in the app. Counting those would push people to use Yui more than helps them, which is the opposite of what Yui is for.

The ledger is designed and tested. Switching it on is Chris's call, and it fills in back to Sep 23 when it starts, because the relay keeps messages for 90 days.

Facts now, a formula later

The ledger stores facts, not points. Before anything is ever distributed, we publish one formula that turns facts into points, and it applies to everyone's history the same way. So we never have to promise a rate today, and nobody's early days are worth less because the formula came later.

Open parts of the formula: how a day of use weighs against a merged pull request, a daily cap so gaming it does not pay, and a bonus for being early.

What it could become, later and only after counsel

What $U becomes is still open. Maybe something you spend inside Yui, like an in-game currency. Maybe a share of Yui itself, because equity is part of the idea. Probably both. It is an idea and a principle Yui wants to explore, in the open, with a lawyer reading every step first. No token exists yet, and nothing is for sale.

Guardrails

What the site says

The home page teases it in a few lines: use Yui early, it counts, we are starting a private ledger back to day one, what it turns into is being worked out in the open, no token exists and nothing is for sale. It links to /earn. No token names, no dates, no amounts.

Open questions

  1. The formula: weights, caps and the early bonus.
  2. Linking a GitHub handle to a Yui account, opt-in.
  3. Account deletion: deleting an account deletes its ledger rows today. Should a person be able to keep a copy?
  4. The form a stake takes: counsel's call (/earn).
  5. When a person first sees their own record: in the app, much later, or on the site before that.

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.
