Simular's computer-use agent that runs fleets of autonomous computers in parallel.
Sai, by Simular, is a generally available computer-use agent built around the #SaiFleet concept: instead of one agent on one computer, users deploy fleets of autonomous computers that work in parallel. Sai reads screens, clicks, types, navigates apps, and plans its next move, operating software with no API including legacy desktop apps and logged-in portals. It runs on Windows, macOS, and Linux, on Simular-provisioned cloud VMs or your own device, asks permission on critical actions, and delivers results via iMessage, SMS, or Telegram.

Automation and agent tools promise to do work for you, so judge them on reliability before cleverness. Map the exact workflow you want to automate, then check the tool's integrations cover every app in that chain — one missing connector breaks the whole flow. Look for clear triggers, sensible limits, and logs you can read when something goes wrong, because something eventually will. For agents that act on your behalf, approval controls matter: you should be able to review messages, purchases or changes before they happen, especially at the start. Pricing usually scales with runs or tasks, so estimate your monthly volume honestly. Start with one low-risk workflow, measure the time it truly saves, and expand from there.
