Perplexity has launched a new feature called Personal Computer that transforms a Mac into an always-on AI assistant capable of interacting with local files, native apps, and the browser. Positioned as a practical "AI employee," the system can handle cross-app tasks from a single prompt, such as reading notes, drafting emails, replying in iMessage, and pulling information from open files and tabs.
The key innovation is convenience: instead of requiring terminal setup, API keys, or custom model configuration, the tool activates with a simple shortcut and responds to voice or text commands. This makes advanced desktop automation accessible to mainstream users rather than just technical operators.
Setting up the feature takes five steps: subscribe to Perplexity Max, install the Perplexity Mac app, run it on a Mac with macOS 14 or later, activate Personal Computer, and start prompting. For users who want persistent AI help on a dedicated machine, the business value is clear. The viral appeal comes from replacing complex automation workflows with a simple, consumer-grade experience.
