Introducing Portable Computer for local-first AI

Perplexity has launched Portable Computer, a local version of its AI agent platform developed with NVIDIA that runs entirely on NVIDIA DGX Spark systems and is planned for future NVIDIA RTX GPU PCs. Designed for private codebases, confidential documents, and other sensitive work, it processes files, searches local data, executes workflows, and maintains planning, scheduling, routing, and indexing functions on the user’s device without consuming cloud credits. It uses Qwen 3.8 27B or Perplexity’s post-trained PPLX 27B model, with NVIDIA Nemotron 3.5 Lightning planned as an additional option, and can request permission to escalate specific tasks to cloud services for web research, connected applications, or advanced reasoning while retaining sensitive local information. The platform supports connectors such as Google Drive, Gmail, Slack, and GitHub, offers locally processed dictation through NVIDIA’s speech-recognition model, and uses sandboxed execution environments for security. Portable Computer is initially available to Perplexity Pro and Max subscribers on Linux-based NVIDIA DGX Spark hardware, with Windows support expected later.
