Perplexity Brings Agentic 'Personal Computer' Feature to Windows

Perplexity has expanded its agentic AI feature, Personal Computer, to Windows 10 and 11, according to a hands-on report from ZDNET. The feature was previously available only on macOS and lets Perplexity's AI complete multi-step tasks on a user's computer with minimal manual input.

What Personal Computer Does

Access to Personal Computer requires a paid Perplexity subscription — Pro, Max, or Enterprise. Pricing for these tiers was not specified in the source report. Once installed via the Perplexity Downloads page or Microsoft Store, the Windows app can interact with a user's environment in three ways: reading and writing local files, operating native Windows applications, and connecting to cloud services including OneDrive, Google Drive, Box, and Dropbox. The app also supports voice mode for back-and-forth conversation before task execution.

Users must explicitly enable local file access on first launch, and third-party service connectors (e.g., Microsoft 365) are added manually through a Customize menu. Perplexity offers a selectable range of underlying models for the Computer function, though the default model is recommended for most tasks.

Reported Task Performance

ZDNET contributor Lance Whitney tested five tasks on the Windows version, mirroring an earlier test he ran on macOS:

1. Local PDF summarization — Perplexity scanned a Downloads folder, summarized medical record PDFs into a two-page document, identified duplicate files, and produced a downloadable summary.
2. Cloud document summarization — Using a Microsoft 365 connector, the AI searched a OneDrive folder for articles matching a topic and generated a five-page summary saved as a new Word document. Whitney, who authored the source articles, reported no factual errors or hallucinations.
3. Email triage — The AI scanned six months of Outlook folders across multiple accounts, identified six unanswered emails, and drafted replies for review before sending.
4. Recurring task scheduling — Perplexity set up a daily check (around 9 a.m. ET) for news updates on a specified topic, agreeing to surface source, date, and relevance for future alerts.
5. File format conversion — Converting legacy .doc and .xls files to modern formats proved the most difficult task, with the AI initially blocked from folder access and unable to write files to a new directory. It eventually completed the task after multiple workarounds and some user intervention.

Whitney reported that earlier versions of the Windows app threw errors when tasks required local folder access, an issue he said has been resolved in the current release.

What this means

This is a platform expansion, not a new model release — Perplexity is porting an existing agentic capability from macOS to Windows, widening its addressable user base rather than shipping new underlying AI. The report is a single reviewer's hands-on account rather than an independent benchmark, and reliability issues surfaced in at least one of five tasks, suggesting the feature is functional but not yet frictionless for file-system-level operations. For enterprises evaluating desktop AI agents, the OneDrive/Outlook integration is notable because it tests real credentialed access to cloud services rather than sandboxed demos — an area where competitors like Microsoft Copilot and Anthropic's computer-use tools are also actively pushing. The lack of disclosed pricing for the underlying subscription tiers required to use this feature limits how directly it can be compared to alternatives.
