Perplexity’s Personal Computer turns your spare Mac into an always-on AI agent

Perplexity rolled out Personal Computer, a 24/7 AI agent that runs on a dedicated device on your local network to turn a spare Mac (and potentially a Mac Mini) into a private AI assistant with full access to files and apps, controllable from anywhere. It’s pitched as more secure than rivals with features like an audit trail, the ability to reverse actions, and a kill switch; access is via a waitlist while the service is prepared for broader rollout, and a video demo shows it drafting emails, turning reports into slides, and ranking job candidates for professional use.
