Perplexity launches a Mac “Personal Computer” that turns a Mac mini into an always-on AI agent
Perplexity just crossed a small but meaningful line: it’s turning an AI assistant into something closer to a personal operating layer. Today, the company officially rolled out Personal Computer for Mac, an expansion of its earlier Perplexity Computer that’s designed to work with local files and apps.
The setup is intentionally practical. Perplexity Computer launched earlier this year as an all-in-one “digital worker” that can create and execute entire workflows. With Personal Computer, the system can run directly on a Mac, with access to the file system and native apps. And yes, it’s meant to feel fast to trigger—pressing both Command keys on a Mac activates it. It can then respond to text or voice commands, and it can work across any Mac app.
One of the more “day to day” claims is that it doesn’t just run in the background—it can see active apps and display quick actions automatically. For people who’ve tried to wrangle AI through separate tabs and copy-paste loops, that matters. It’s like reducing the friction between “ask” and “do,” though whether it always feels seamless in practice… well, that’ll depend on how messy your real workflows are.
Perplexity says Personal Computer can run on any Mac with macOS 14 Sonoma or later, but it recommends a Mac mini. The reason is pretty straightforward: a Mac mini can run 24/7, which supports work that needs a persistent machine—or secure, local access to files and native apps. Perplexity also says tasks can be initiated and managed from an iPhone when you’re away. I can imagine the moment of trying it—maybe you’re in the kitchen, phone buzzing on the counter, and you hear the faint clicking of keys back at your desk. That’s the kind of “always on” workflow Personal Computer seems built for.
What the agent can do covers the unglamorous stuff that actually eats time. Perplexity says Personal Computer can complete each task on a to-do list, sort a messy downloads folder, compare local files against information on the web, and more. It can also create teams of agents across over 20 frontier models to complete tasks. Actions are visible, so users can step in when needed—important, because letting an AI act on your machine is great right up until you want to pause it and say, “Wait, no.”
There’s also a control layer meant to calm that concern. Files are created in a secure sandbox, the actions Personal Computer takes are auditable and reversible, and there is a kill switch. Perplexity Max subscribers get the rollout first, with waitlist members prioritized. Pricing is also part of the picture: Perplexity Max costs $200 per month, and the new feature isn’t available to $20/month Pro plan subscribers.
If Personal Computer lands the way Perplexity is describing, it could make “agent” less of a buzzword and more of a routine tool. But the real test won’t be the headline—it’ll be how reliably it handles messy file structures, how clean the reversibility feels, and whether the activation flow stays intuitive after a few days of use. For now, the company is rolling it out today—and pressing Command keys is suddenly… a little different.
