The race to build practical, local AI agents that can autonomously operate your computer on your behalf is accelerating, and Perplexity's rollout of Personal Computer to all Mac users is the latest signal that this category is moving from experimental to mainstream. The demand has been clearly demonstrated by OpenClaw, which popularized the idea of AI agents with elevated system permissions capable of performing tasks on users' behalf across applications and files. But OpenClaw also surfaced a set of serious security concerns that have shadowed the entire category — its elevated permissions model presented risks significant enough that security researchers and publications flagged it as a meaningful threat vector for users who granted it broad access to their systems. Perplexity is explicitly positioning Personal Computer as a safer alternative, running agent operations within a secure development environment on its own servers rather than directly on the user's machine with unrestricted permissions.

Whether that architecture fully resolves the security concerns inherent in giving any AI agent broad access to your local files, applications, and web activity is a question that will be stress-tested as the user base scales. The honest answer is that no local AI agent is without tradeoffs between capability and security surface area, and users should approach any tool in this category with a clear understanding of what access they are granting and to whom. That said, the practical productivity case for well-designed local AI agents is genuinely compelling — the ability to automate multi-step workflows that currently require manual switching between applications, file formats, and web tools represents a real and meaningful reduction in cognitive overhead for knowledge workers. Perplexity's entry into broad availability, combined with the Comet browser integration and remote iPhone access, makes Personal Computer one of the most fully featured local agent products currently available to everyday Mac users — and the competition with OpenClaw and whatever OpenAI brings to this space is only going to intensify from here.
