Perplexity launched "Personal Computer," an AI platform that shifts the operating system model from manual instruction execution to probabilistic goal completion. The agent utilizes deep web research as its core foundation to autonomously evaluate reasoning paths and drive multi-step workflows. This architecture transforms the computer into an active orchestrator, eliminating the administrative friction of managing fragmented software tools.
