Sai
Sai is a computer-use agent from Simular AI that operates a private cloud Windows computer, or the customer's own Windows or Mac device, by clicking and typing through browsers, desktop apps, file systems, and terminals. It runs recurring tasks unattended in the background, asks for approval before critical steps, and reports results over iMessage, SMS, or Telegram. Business professionals, founders, and researchers use it as a personal assistant for repetitive computer work.
