AI tools are steadily moving beyond chatbots that simply answer questions. Companies are now experimenting with AI systems that can actively manage tasks and work in the background for long periods. The latest example comes from Perplexity AI, which has introduced a new concept that could turn a small desktop computer into a constantly running AI-based employee.
The system, called Perplexity Personal Computer, is designed to run on a nearby machine such as the Mac mini. Instead of functioning like a typical AI tool that only responds to prompts, the setup allows the AI to remain active on the computer and interact with files, apps and tasks over time.
The idea builds on Perplexity’s earlier “Perplexity Computer” platform, which works like a manager for multiple AI agents. When a user gives it a goal, the system breaks the work into smaller tasks and assigns them to different AI agents. Once the work is done, the results are combined and presented back to the user.
An AI employee that keeps working in the background?
The Personal Computer version extends this concept by linking the AI to a user’s local machine. Because it runs on a device like the Mac mini, the system can access files stored on the computer and perform tasks that involve personal data.
For instance, if someone has a folder full of images and wants them prepared for a website, the AI could analyse the photos, rename them in a structured format and resize them for online use. Instead of manually organising everything, the user simply describes the outcome.
The system is designed to remain active all the time. As Aravind Srinivas explained while announcing the project, “It never sleeps.” However, the company says the AI processing itself will still happen on Perplexity’s servers. Sensitive actions will require approval, activity logs will be available, and users will also have a kill switch to disable the system if needed.
Why the Mac mini is part of the idea
The Mac mini has recently become popular among developers experimenting with locally hosted AI systems. Compared to more powerful machines such as the Mac Studio, the compact computer offers a relatively affordable way to run lightweight AI tools.
Perplexity’s move also comes at a time when several projects are exploring AI agents that automate digital work. One example is OpenClaw, which allows AI agents to coordinate tasks across different software tools.
Srinivas suggested that Perplexity’s approach is aimed at making such systems easier to adopt.
“Perplexity PC is meant for serious people—I really mean that! A personal computer should help in your life.”
He also pointed out that many open-source agent systems are difficult to set up.
“Not for hobbyist tinkerers with 700 API keys & configs. Even our best engineer took ages on OpenClaw, but we scale adoption easily.” The concept has already sparked discussion online.
One user on X reacted to the idea by writing, “This is insanePerplexity just put an AI agent inside a Mac mini. You plug it in. It sits on your desk. It never turns off. This is not a chatbot. This is a virtual employee that lives in your house and works 24/7.”
At the moment, Perplexity Personal Computer is not widely available, with the company opening a waitlist for early access.
