AI startup Perplexity AI has announced the launch of Personal Computer, a new product designed to function as a digital proxy that can perform tasks on behalf of users.
The announcement comes just weeks after the company introduced another agentic tool, signalling its continued push into autonomous AI assistants.
According to the company, Personal Computer is built to “orchestrate all of your tools, tasks and files from any device, anywhere.” In simple terms, it acts as a persistent AI assistant capable of researching topics, drafting emails, generating daily briefings and managing workflows without requiring constant supervision.
The system runs on a dedicated Apple Mac mini device and operates within a secure environment designed to protect user data. It also maintains a detailed audit trail of every session and requires explicit user approval before executing sensitive actions, giving users transparency and control over what the AI agent does.
Personal Computer supports multiple leading large language models, allowing users to choose between models such as Claude, Gemini and Grok. A notable feature is its ability to run several models simultaneously, enabling them to interact with each other to refine responses or complete complex tasks.
At launch, the product supports Mac systems, though Perplexity said it is developing an enterprise version that will include features such as single sign-on for organisations.
The launch also comes alongside several enterprise-focused offerings from the company, including Computer for Enterprise, Comet Enterprise and a new set of developer APIs covering search, agents, embeddings and sandbox environments.
