How it works

How a computer use agent works across your Mac ?

01 - Describe the task in plain language

Sai works with the Mac apps and sites you already use, with no integration work. Say what needs to happen, not how to click through it.

02 - Run it on your Mac, or on a private cloud desktop

Keep it local on Apple Silicon, or hand it to an isolated remote machine so your own setup stays untouched.

03 - It operates the software itself

Clicking, typing, navigating — this is what a computer use agent does. Every step is readable, and critical ones wait for your approval.

04 - Teach once, then put it on a schedule

Save the run as a workflow and it repeats without you — nightly, weekly, or on a trigger.
