What they do

Problem

Traditional operating systems constrain users to single-device, single-environment workflows that limit true parallel work between humans and AI agents across apps and OSes.

Solution

InfinityOS is a cloud-based operating system that runs each app in its own isolated virtual computer with dedicated GPU and inputs, enabling concurrent Windows/Linux apps and human-agent collaboration in the browser.

Who it's for

Power users, developers, and teams who need to run many apps/OS environments concurrently and collaborate with AI agents from any device.
