Perplexity announced on September 14 that its on-device AI agent, Portable Computer, now supports Windows PCs[1]. The feature works on NVIDIA GeForce RTX and NVIDIA RTX PRO Workstation systems with 24GB or more of VRAM, extending the Linux and NVIDIA DGX Spark support that launched in late August[1][2]. The agent keeps sensitive information on the device while handling multi-step tasks.
From Linux to Windows in About Three Weeks
Portable Computer is a local version of Perplexity's agent platform, Perplexity Computer. It first launched on Linux and NVIDIA DGX Spark on August 25, with Windows support already flagged for September at that time[2][3]. Today's announcement delivers on that plan: compatible PCs need an NVIDIA GeForce RTX or NVIDIA RTX PRO Workstation GPU with at least 24GB of VRAM[1][3]. Support for NVIDIA DGX Station is described as coming soon and is not part of this release[1].
Cloud Access Requires the User's Permission
Portable Computer handles multistep tasks such as organizing files, coordinating tools and managing recurring work, all processed by a model running locally on the PC. Work completed on-device does not consume Perplexity Computer credits[1]. For tasks that need heavier reasoning, the agent can hand off to cloud models, but only after asking the user for permission to send information off the device[1].
The app runs local models such as Qwen 3.8 27B, which has been optimized for NVIDIA RTX GPUs, so users don't need to research models or configure a complex local AI stack themselves[1]. Portable Computer also connects to everyday work tools, including Microsoft Outlook, OneDrive, Word, Google Drive, Gmail, Slack and GitHub[1].
What the Agent Can Actually Do
NVIDIA's examples include an engineering use case where the agent reviews open pull requests in a connected GitHub project, sorts them by status and flags outdated documentation[1]. A finance example has the agent trace two years of brokerage statements and tax returns to find recurring fees, citing the exact file and page for every figure without the documents ever reaching a chatbot[1]. A startup-focused example has the agent analyze a local funnel export to find where signups drop off, then post the findings directly to a team's Slack channel[1].
Available to Pro and Max Subscribers, NVIDIA-Only for Now
Portable Computer is available to Perplexity's Pro, Max, Enterprise Pro and Enterprise Max subscribers[2][3]. Supported hardware currently centers on NVIDIA GPUs, and Apple Silicon support is not on the roadmap at this time[3]. By letting users choose between local and cloud processing, the release highlights how privacy and cost considerations are shaping the practical use of AI agents.
Summary
Perplexity announced Windows support for its local AI agent, Portable Computer, on September 14. It runs on NVIDIA GeForce RTX and RTX PRO Workstation PCs with at least 24GB of VRAM, extending the Linux and DGX Spark support that debuted in August. By processing work on-device and only reaching out to the cloud with the user's permission, the release is aimed at agentic workflows involving sensitive data.
