Perplexity has extended its Personal Computer desktop agent to Windows. The tool, launched on Mac in April, operates as a “general-purpose digital worker” with access to local files and apps to perform actions on behalf of the user: create documents, update spreadsheets, move between disk and web. The Windows version closes the gap between the Office 365 and Teams integrations that arrived in May and the operating system where, according to Perplexity, enterprise work happens locally and was so far “beyond the reach of AI”.

Why it matters. Desktop agents with access to local desktops have so far stayed within Apple’s walled garden. Windows covers about 90% of business PCs: this means anyone building automations has a new channel to target. If you have a workflow that runs through local files, Excel and web searches, there’s now a tool that tries to close it in a single interface. Perplexity says it doesn’t train on business data and asks for confirmation before sensitive actions like sending emails or deleting files. The real test is how it holds up on actual, repeatable tasks, not on the demo.

Available today for Max and Enterprise Max subscribers, with plans starting at 200 dollars per month.

In detail

Perplexity launched Personal Computer on Mac in April 2026 as a first step to bring its agentic search engine into the user’s operating system. In May it added integrations with Microsoft 365 and Teams. Today’s Windows release completes the picture: the agent doesn’t just rely on cloud APIs from Microsoft services, but operates directly within the Windows environment, with access to the local filesystem.

The practical difference is sharp. An agent that lives in the browser can read email via API or search the web, but can’t see the folder with customer files on the desktop, nor can it open a local Excel file to update it. Personal Computer for Windows tries to close that gap, which Perplexity describes as where “messy enterprise work” actually happens: scattered files, local versions, appointments jotted down on calendars that don’t talk to any system. In theory, this means a professional can ask the agent to gather data from a PDF on the desktop, cross-reference it with a web search, and fill in a Word report, all in one sequence without switching windows. Until now, getting the same result required at least two separate tools and a manual handoff.

Pricing stays steep. Max and Enterprise Max plans start at 200 dollars per month, clearly positioning the tool in the professional and enterprise segment, not general consumption. Perplexity highlights two security guarantees: no training on business data and mandatory notification before sensitive actions (sending email, deleting files). This is a pattern consolidating among computer-access agents: permissions matter more than the underlying model. Anyone evaluating these tools should first look at which actions require explicit confirmation and which run automatically, because that’s where real risk is decided, not in model power.

The limits are evident. There are no independent tests yet on repeatable tasks, and the “general-purpose digital worker” idea is the same formula we’ve seen applied to still-immature tools in this category. Operating inside Windows helps those locked in the Microsoft ecosystem, but real quality will be measured on concrete workflows: an agent that needs to update thirty local Excel sheets following specific business rules, manage nested folders, and recognize when data doesn’t add up, not a demo with two sample files. For anyone building automations, it’s worth watching the channel, but verify on your own use case before committing to it.
