Perplexity is putting an always-on agent straight onto the Windows desktop. You hand it a goal — “build an interactive guide on whales,” “clean up this spreadsheet” — and it decides which apps to open, which files to touch, and how to finish the job across Excel, PowerPoint, Word, Outlook, and OneDrive.

## What it actually does

This isn’t a chatbot stuck in a sidebar. Personal Computer acts on your machine: opening local apps, reading local files, chaining steps toward an outcome instead of answering one question at a time. It was announced June 2 alongside Intel, is slated to launch in July, and is waitlist-only for now.

## Why the routing matters

The real trick is the hybrid reasoning system. Sensitive data — financial records, medical files — gets handled by small on-device models, while heavy workloads route out to cloud models. The same framework also runs on NVIDIA’s RTX Spark silicon. It’s a privacy-versus-power tradeoff made automatically, and that’s exactly the bet that makes a desktop agent something people might actually trust with their files.
