Sai

Sai by Simular AI is a robosecretary that commands a fleet of autonomous computers to handle repetitive screen work. Each computer navigates software the way a human does—reading the screen, clicking buttons, and filling forms—so Sai can automate tasks even in apps without APIs, including legacy desktop applications, internal portals, and anything behind a login. It supports Windows, macOS, and Linux, and the team reports a 73% score on the OSWorld benchmark.
