Perplexity Launches Personal Computer, an Always-On AI Assistant Running on Mac Mini.

Perplexity has launched Personal Computer, a new service that positions an always-on Mac mini as a personal AI workstation that users can control from anywhere. The announcement marks the company's latest move beyond its core search product, following their recent Computer platform launch.

The service combines a physical Mac mini running locally with Perplexity's cloud infrastructure to create what the company calls a "local merge" that operates continuously. Users can access their Personal Computer from any device, with the Mac mini handling integrations with local files, applications, and ongoing sessions while maintaining a persistent connection to Perplexity's servers.

Perplexity emphasizes that Personal Computer runs in a secure environment with user-controllable access. The architecture keeps the Mac mini connected to both local resources and Perplexity's infrastructure, creating a hybrid system designed to handle tasks that require both cloud intelligence and local data access.

The company positions this as a step toward making AI assistance more personal and context-aware, since the always-on Mac mini can maintain state across sessions and access files and apps that cloud-only services typically cannot reach. The tradeoff is requiring dedicated hardware rather than operating purely in the cloud.

Starting today, users can join the waitlist for the Personal Computer program. Perplexity plans to onboard an initial cohort with dedicated support and resources, suggesting a measured rollout rather than immediate broad availability.

The announcement leaves several implementation questions unanswered, including pricing structure, whether users must provide their own Mac mini or if hardware is included, and how the service handles data synchronization and privacy. The company also has not detailed which specific local apps and file types will be supported at launch.

Personal Computer represents a different approach to AI assistants compared to cloud-only offerings like ChatGPT or Claude. By anchoring the service to dedicated hardware, Perplexity aims to provide deeper integration with users' existing workflows and data, though this comes with the overhead of maintaining physical infrastructure.

The move follows Perplexity's broader strategy of expanding beyond search into productivity tools, including their Computer for Enterprise launch with Slack integration. Personal Computer appears designed to serve individual power users who need persistent, locally-integrated AI assistance rather than occasional query-based interactions.

Whether the market demands always-on, hardware-based AI assistance at scale remains to be seen. For now, Perplexity is testing the concept with a limited cohort before committing to wider availability.
