Earn with your phone

Your phone can do small, checked pieces of AI work in this browser tab while its screen is on. Test batches earn credit for renting compute here; real work for API customers, when there is some, earns money you can withdraw. The test below shows whether this phone can do the work, and how fast.

Before you start

Downloads
About 115 MB of AI model the first time — use Wi-Fi. The browser keeps it after that, so coming back downloads almost nothing.
Takes
About a minute for the test. Earning runs one short batch a minute for as long as you leave this page open.
Uses
The graphics chip, or the processor when the fast path is not available. A batch of work takes a second or less; keeping the screen on is what drains the battery, so keep the phone plugged in.
Needs
A recent iPhone, iPad or Android phone. We check below — no version to look up.
Earns
Spend-only credit: 1¢ for every 300 verified batches, at most 60 batches an hour — about 0.2¢ an hour, however fast the phone is. It pays for renting compute here and can never be withdrawn. Earning needs an account; the test does not.
API work: when customers send text to process, this phone does it too and is paid real money you can withdraw — 70% of what the customer pays, shared between the phones whose answers agree. Up to a few cents an hour while there is work; nothing when there is none.
Stores
On our server, for each test run: how accurate and how fast it was, whether the graphics chip or the processor did it, and the name and version your browser reports (its user agent). The test needs no account. On this phone: the model, so the next visit does not download it again — clearing this site's data removes it. While you earn, the server also keeps which batches your account took and whether each came back, your count of verified batches, and the credit on your account.

Loads the model, embeds 8 fixed sentences, and asks the server to grade the answers against known-correct values.

Why the screen has to stay on

A browser tab only runs while it is on screen. The moment you switch apps, lock the phone, or even move to another tab, iOS and Android suspend the page — that is an operating-system rule, not something a website can opt out of. Keeping the screen awake is the most a web page is allowed to ask for, and even that is released automatically the instant the page stops being visible.

So a phone only works while you leave this page open with the screen on — and since that is what drains the battery, keep it plugged in while it does.
