The control
What it can really operate
This is what exists today, with its limits. For it to control the phone you have to switch on the Android accessibility service by hand, the permission that lets an app tap the screen for you.
The computers
From the chat you choose which computer does the next thing, see live how busy it is and can cancel whatever it is running. The agent only works inside the folders that computer allows.
The phone
Open an app, tap a button by its text, type into the active field and read the screen. That is enough to chain tasks together, but it does no gestures or swipes: just those four actions.
Websites and servers
Code changes, domains and their email, and new servers. Anything that costs money asks for explicit confirmation first.
The home
Samsung TV over the network (on, off, volume, channel, HDMI and opening apps), air conditioning and lamps using the codes it learns from your infrared remotes, and the robot vacuum.
