Like a copilot for every Mayfair app.
One assistant, one memory and one plan, inside the Mayfair apps you already use. Each app decides what it offers, and you decide what is allowed.
Mayfair apps, one assistant, one memory, your permissions and your approvals.
The assistant, inside the app.
A Mayfair app adds Artemii with one script tag. A launcher opens a side panel on desktop and a bottom sheet on phones, in light or dark.
- It signs in with the Mayfair ID you are already using
- The app tells it what you are looking at, and shows you exactly what is shared with a "Using" chip you can switch off
- The app can give it actions. Anything that changes data shows an Allow or Deny card first
- Usage counts against your plan, like the Artemii app
Using: Q3 pricing proposal
An example of the chip the panel shows above the message box. Click it to see exactly what is shared with the assistant, and use the switch to share nothing.
It remembers across apps.
One memory
Something Artemii learns in one place can help in another, because every Mayfair app reads and writes the same per-person memory.
Per-app switches
Each app has its own switch: off, read, or read and write. Apps Mayfair has not registered are off.
Sensitive data filtered
Every write, from any app, passes the same filter that refuses cards, passwords, health details and the like.
Let it act inside the app, as you.
A Mayfair app can publish actions, such as "search my mail" or "create an event". Artemii calls the app with your own sign-in token, so the app decides what you may do exactly as it does for its own screens.
- Every action says honestly whether it only reads or changes something
- Reads run. Changes ask you first, unless you set the app to allow
- The app checks your token and a signature from Artemii on every call, and logs the call as made via Artemii
- You can switch any app off in Settings, and see what it did in the activity log


Built, and rolling out app by app.
The embeddable assistant, the app tools protocol and shared memory are built and tested against a test Mayfair ID. Each Mayfair app adopts them on its own schedule, so we do not list which apps have it switched on here yet. We will add them as they go live.
