Perplexity brings its 'Personal Computer' AI agent to Windows

Perplexity expanded its agentic Personal Computer tool to Windows PCs, after launching it for Mac in April. It acts as a general-purpose digital worker that can access local files and apps to perform tasks like creating documents and updating spreadsheets on a user's behalf.

Why it matters: This pushes autonomous desktop agents from a niche Mac feature to the dominant PC platform, putting Perplexity in more direct competition with Microsoft's own Copilot agents on their home turf. It's also another data point in the broader shift toward AI systems that act directly on local files and apps rather than just chatting.
