Perplexity just took its AI agent past the Mac and onto Windows, the operating system that runs most computers in offices worldwide. The product is called Personal Computer. It works like a digital assistant that can open your files, edit a spreadsheet, draft a document, and pull information from the web, without you doing the clicking yourself.
This is not Perplexity's first step into this space. The company launched the same tool for Mac back in April, then added the ability to work inside Microsoft's 365 apps and Teams in May.
The Windows version closes the loop. Most of the paperwork inside a company, invoices, spreadsheets, internal reports, sits on Windows machines, not Macs.
Perplexity started as a search engine built to challenge Google. Over the past year it has turned into something else: a company selling a browser called Comet that can browse and shop on your behalf, and now a desktop agent that can run tasks across your entire computer.
Perplexity closed a funding round that pushed its valuation to around 20 billion dollars in September 2025. Comet itself went from a paid product to a free one within months, a move that has more to do with pulling in users than earning money from the browser directly.
Personal Computer is where the actual business model shows up. It sits inside Perplexity's Max plan, priced at 200 dollars a month, with pricier Enterprise Max seats built for larger teams.
The price tells you who this is really built for. It is not aimed at someone checking email at home, but at businesses paying per seat to replace hours of manual admin work, the kind of task that eats up a back-office day: pulling numbers into a spreadsheet, drafting a report, digging through old files for one number.
Perplexity is not alone in this race. Microsoft has been building similar "computer use" tools directly into its own Copilot Studio, letting agents click buttons and fill forms inside Windows apps, while OpenAI extended computer control to Windows through its Codex tool this year and Anthropic's Claude can also take over a computer to finish tasks on its own.
Much of this activity picked up speed after an open source tool called OpenClaw went viral for doing exactly this kind of work, briefly becoming one of the most popular software projects ever released. That race matters even if you never open any of these products yourself.
If your job involves moving information between systems, drafting reports, updating spreadsheets, or repetitive research, this is exactly the kind of task these agents are built to take over. Perplexity's own materials describe this as the messy way enterprise work actually gets done on local machines, which is a fairly accurate description of a lot of back-office jobs today.
The real question is trust, not capability. Letting software click through your files, send emails, and delete things on its own carries real risk, and security researchers already point to data leakage and manipulated instructions as fast-growing problems tied to these agents.
Perplexity says it does not train on company data and will ask before sensitive actions. Whether that promise holds up under everyday business use, with real files and real deadlines, is the part worth watching over the next year.
