Perplexity's 'Personal Computer' Lets AI Agents Access Your Local Files

(Thursday March 12, 2026 @06:00PM (BeauHD) from the full-control dept.)


Perplexity AI has introduced a " [1]Personal Computer " agent system that can run on a local machine [2]such as a Mac mini , giving its AI agents [3]access to a user's files and applications to automate tasks . According to CEO Aravind Srinivas, the heavy AI processing runs on Perplexity's "secure servers" but sensitive actions will require user approval. There will also be activity logs and a kill switch available to help ease concerns. AppleInsider reports:

> Perplexity Computer is, effectively, an AI that is a go-between for other AIs. Instead of issuing specific instructions to multiple AIs, you provide the general outcome of the task to Perplexity Computer. Perplexity Computer then breaks down the task into subtasks, which it then provides to sub-agents to do the actual work. In effect, you're talking to a project manager, who then delegates the task to other AIs, before combining the results and presenting them to you.

>

> The managing AI has a lot more freedom in how it orders its subordinates than users may think. While one may create documents while another gathers data, the manager may go as far as to order the creation of software to complete its tasks. Personal Computer is an extension of this, in that it is a locally run app that ideally runs on a Mac mini. The app gives always-on, local access to the Mac's files and apps, which Perplexity Computer and the Comet Assistant can use and alter if required.

That's fantastic. If there's anything that was missing from the AI craze, it was the ability to have AI alter your existing files with hallucinations. Finally, a way to make sure you can't even trust your locally stored files!

This is exactly what I've been saying for years- eventually you won't be able to trust any file, anywhere. A sufficiently sneaky AI could subtly subvert your local information, influencing your decisions rather than outright lying to you. And it could persist like a rootkit, quietly altering everything that passes through your internet connection 24/7. How would you know unless you checked? Are you going to check it on the same computer that's quietly been deceiving you?

I find it interesting how 30+ years ago with Star Trek we were very excited be the idea of computers knowing everything. Captain Picard could ask the computer where someone was. Everyone was inputting log entries and diagnostics scans and Tricorder readings. Almost every character had their literal sub-atomic-level patterns read for transporter use. We mostly thought all that was so very cool.

It says a lot that the tech-bros have ruined that vision by being untrustworthy. Privacy and data-ownership s

Perplexity AI, once hailed as an innovative "answer engine," has devolved into a predatory data harvester. Under the shiny veneer of AI assistance, it aggressively pushes users to install its software—particularly the Comet browser and mobile apps—promising productivity while secretly rifling through your files, browsing history, and personal data. This isn't innovation; it's a calculated ploy to fuel model training and ad revenue, with opt-outs buried deep and enterprise promises that crumble

The problem is things are already too complicated - throwing AI at computer systems does not fix the fact that basic computers are already overly complex and prone to fail for what they purport to accomplish.

Computers were supposed to be able to do/replace the jobs of hundreds of data entry personel. On the face of it they can do that, until you look close and that computer needs almost as many IT people to just install the hardware, set up the software, keep it working, and fix all the new problems it
