Perplexity has introduced a fully local version of its AI Computer for supported Apple silicon Macs, giving users the option to complete complex, multi-step tasks directly on their computers. Announced on October 20, 2026, the update is designed to help users manage files, work across supported Mac applications and process sensitive information without routinely sending that information to cloud servers.
The new mode represents a further step in Perplexity’s efforts to bring AI-powered task automation to personal computers. Instead of relying entirely on remote servers to process requests, the local version runs the AI model and the system responsible for planning and executing tasks on the Mac itself.
The feature is available through the Perplexity Mac application to subscribers on Pro, Max and Enterprise plans. It requires a supported Mac powered by Apple silicon. Perplexity recommends a system with at least 36GB of memory for running Computer locally.
How Does the Local AI Computer Work?
Perplexity Computer is designed to do more than answer questions. It can plan workflows, process information, use supported tools and carry out a series of related tasks to produce a completed result.
In the new local mode, the AI model, task planning, reasoning and file processing run directly on the user's Mac. This reduces the need to transmit private documents and other sensitive information to remote servers during tasks that can be completed locally.
Perplexity says the local version launches with two model options, Qwen 3.6 and PPLX Pro, a Perplexity model based on Qwen. Users can download and configure a local model through the Mac application before selecting the fully local option.
The computer's own processing resources are used to run the workflow. As a result, performance will depend on the Mac's hardware capabilities, available memory and the complexity of the task.
Work Across Mac Applications and Local Files
One of the main features of the update is the ability to work with local files and supported native Mac applications after the user grants permission.
The supported applications include Notes, Mail, Messages and Numbers. This allows the AI assistant to combine information from different sources on the computer and prepare useful outputs.
For example, a user could ask Computer to review a to-do list in Notes, identify deadlines mentioned in Messages and examine budget figures stored in a spreadsheet. It could then organise the information into a status report and prepare follow-up material.
Other possible uses include reviewing confidential documents, preparing client proposals, organising project information and summarising work-related communications.
These capabilities could be useful for professionals who regularly handle sensitive business information. Instead of manually moving information between applications, users can delegate several connected steps to the AI assistant.
However, access is permission-based. Users should review the access requested by the application and understand which files and applications the assistant can use before authorising a workflow.
Privacy and Data Protection
Data privacy is a central part of Perplexity's announcement. By processing information directly on the Mac, the local mode gives users more control over how private files are handled.
When a task remains fully local, the AI model can analyse information and execute supported actions on the device without sending the task's sensitive contents to Perplexity's cloud servers.
This approach may appeal to people working with confidential financial documents, client records, internal reports or personal correspondence. Keeping processing local can reduce exposure associated with transferring sensitive information to remote services.
Perplexity also states that code and tool execution take place in isolated sandbox environments with controlled access to files and connected applications. These safeguards are intended to help restrict what an AI workflow can access while it carries out a task.
Nevertheless, local processing should not be treated as a guarantee of complete security. Users should keep their operating systems and applications updated, review permissions carefully and avoid granting unnecessary access to private information.
Can Perplexity Computer Work Without the Internet?
The fully local mode is designed to support tasks that can be completed on the Mac without an internet connection. Because the model and task-execution system run on the device, users can carry out suitable workflows without depending on cloud-based AI processing.
However, offline functionality has limits. Tasks that require current information from the web, browser access or certain cloud-connected applications may still need an internet connection.
Perplexity allows users to authorise a task to use cloud resources when necessary. The local system can request permission to access advanced cloud models or services for work that cannot be completed entirely on the device. Users therefore retain greater control over when a task moves beyond local processing.
This distinction is important. The new feature does not mean that every Perplexity function is available offline. Instead, it allows compatible workflows to remain on the Mac while providing the option to use cloud capabilities when required.
Availability and System Requirements
The fully local AI Computer is available through the Perplexity Mac application to Pro, Max and Enterprise subscribers using supported Apple silicon Macs.
The company recommends at least 36GB of memory for local operation. Users need to install the latest version of the Mac app, download and configure a supported local model, and select the fully local mode before running a task.
Users with less capable hardware or workflows that require advanced cloud reasoning may prefer Perplexity's Hybrid Compute option. That approach combines cloud-based AI capabilities with local processing for sensitive files and information.
The choice between fully local and hybrid processing will depend on the user's hardware, privacy requirements and the nature of the task.
What the Update Means for AI on Personal Computers
Perplexity's latest update reflects a wider shift towards AI systems that can perform work directly on personal devices. Running AI locally can improve user control over private information and reduce reliance on remote processing for compatible tasks.
For Mac users, the ability to coordinate work across files and native applications could make AI assistants more practical for everyday productivity. The technology may be particularly useful for multi-step workflows that involve organising documents, analysing spreadsheets and preparing reports.
At the same time, local AI depends on suitable hardware and may not match the capabilities of the most advanced cloud models for every task. Users will need to balance privacy, performance and access to current information when choosing how to run their workflows.
With the introduction of fully local Computer for Mac, Perplexity is offering subscribers another way to automate complex work while keeping more of the process on their own devices. The extent of the benefit will depend on the task, the Mac's capabilities and whether cloud access is needed.
