Personal Computer lands on Windows.

On July 28, 2026, Perplexity launched Personal Computer for Windows — its agent platform, now running on the operating system where most office work actually happens. It can open the Word file on your desktop, pull fresh data from the web, update the Excel model next to it, and tidy your Downloads folder on the way out. Here's what it does, the honest catch on who gets it, and the question everyone will ask: what about Copilot?

01 What launched

Perplexity's Computer started this spring as an agent that could research, build documents, and operate web apps. In May it moved into Microsoft 365 — a side panel in Word, Excel, PowerPoint, and Outlook — and into Teams. The missing piece was the machine itself: the local files, folders, and desktop apps where what Perplexity calls "the often messy way enterprise work gets done" actually lives. That's what shipped: the agent now works inside the Windows environment, not just in a browser tab beside it.

The one-sentence version

Ask Computer to do a task, and it can now move between your local files, your Microsoft apps, and the open web in one flow — instead of stopping at the browser's edge.

02 What it can do on your PC

Local files

Create, edit, and organize files on the machine

It can draft or update local Word and Excel files, refresh a PowerPoint deck with current web data before a meeting, and find that elusive file in Downloads and move it to the right File Explorer folder. Files it creates are made in a sandbox, and it's built to save work back to disk so you can review offline.

The Microsoft stack

Office 365, Outlook, and beyond

Personal Computer plugs into the Microsoft 365 integration Perplexity shipped in May, works with Outlook email, and reaches 400+ other tools through App Connectors — pulling Snowflake, Salesforce, or HubSpot data into the spreadsheet it's editing locally.

Hands-free and hand-off

Voice mode and phone-to-desktop tasks

You can talk to Computer to have it carry out actions on the PC, or start a task from your phone at lunch — "update the Excel model on my desktop based on today's news" — and let it finish on the desktop.

Quick check

You ask Personal Computer to "clean up my Downloads folder and email the Q3 report to my accountant." What does Perplexity say happens before that email goes out?

03 The honest catch: who actually gets it

Personal Computer for Windows rolls out to Max and Enterprise Max subscribers only — the ~$200/month tiers. If you're on the regular Pro plan, this launch isn't for you yet, and Perplexity hasn't announced when (or whether) that changes. Also worth calibrating: Perplexity's "$9.4B in labor-equivalent work" figure is the vendor's own estimate, not an audited number.

The security story is more concrete: Perplexity says the agent always alerts you before a sensitive action like sending an email or deleting a file, builds files in a secure sandbox, keeps its actions auditable, and doesn't train on company data under Enterprise. Those are the right design choices — and they're still vendor claims. Give it access to what a task needs, not to everything you have.

04 The Copilot question

Perplexity just parked its agent in Microsoft's front yard. Copilot is built into Windows and Microsoft 365, comes from Microsoft itself, and costs a fraction of Max. So who is this for? The pitch is orchestration: Computer routes work across many AI models and treats Microsoft apps as one stop among many — local files, Google-side tools, Snowflake, Salesforce, and the open web in a single task. Copilot's pitch is depth inside Microsoft's own apps at a price normal teams can justify.

Our read

If your company already pays for Max, try it on a real multi-app task and see if it earns its keep. For everyone else, this launch matters mostly as pressure: the agents-on-your-PC race now has two serious players on Windows, and that competition tends to show up in Copilot's roadmap. Our Perplexity inside Microsoft 365 lesson covers how the two assistants divide the work.

Frequently asked

Personal Computer for Windows — your questions, answered

What did Perplexity launch on July 28, 2026?

Personal Computer for Windows — Perplexity's agent platform running on Windows PCs. It can create and edit local Word, Excel, and other files, organize File Explorer folders, work with Outlook email, research the web, and connect to 400+ tools through App Connectors.

Who can use Personal Computer for Windows?

At launch it rolls out only to paying Max and Enterprise Max subscribers — Perplexity's top tiers, which start around $200 per month. It is not included in the regular Pro plan at launch.

What can it actually do on my PC?

Perplexity's examples include reading a to-do list in Notepad and completing each task across local files, emails, connected apps, and the web; refreshing a local PowerPoint deck with current web data; and finding files in Downloads and moving them to the right folder. Voice mode lets you speak tasks, and a task started on your phone can finish on your desktop.

Is it safe to let an agent touch my files?

Perplexity says Personal Computer always alerts you before sensitive actions like sending an email or deleting a file, creates files in a secure sandbox, keeps actions auditable, and doesn't train on company data on Enterprise. Those are vendor claims — the sensible posture is to give any agent access to what the task needs, not everything you have.

How is this different from Microsoft Copilot?

Copilot is built into Windows and Microsoft 365 by Microsoft itself and is far cheaper for most users. Personal Computer is a third-party agent that orchestrates multiple AI models and reaches across local files, Microsoft apps, and 400+ non-Microsoft tools in one flow. At $200+/month it's aimed at heavy agent users, not everyone.
