Do you prefer running AI tools locally on your device to ensure your private data remains secure?

Perplexity has introduced a local-first mode to its Mac application, allowing AI task processing directly on the device. The update supports planning, reasoning, and file management without requiring a constant cloud connection.

Why it matters

This feature enhances user privacy by keeping sensitive file processing on the hardware, with data only moving to the cloud upon explicit user approval.

The new local-first mode requires an Apple silicon Mac equipped with at least 36GB of unified memory. It includes support for Qwen 3.6 and PPLX Pro local models, with integration capabilities across Notes, Messages, Mail, and Numbers.

The players

Perplexity

Perplexity is an AI-powered search and research engine company that provides conversational answers to complex queries.

Apple

Apple is a multinational technology corporation that designs and manufactures personal computers, smartphones, and software.

The details

Users can download and configure specific local model options directly within the app to perform AI tasks offline. This development builds upon the company's Hybrid Compute platform launched earlier this year.

September 2026: Perplexity launched Hybrid Compute.
October 20, 2026: Local-first mode became available for Mac users.

The Tech Race

This release marks a significant move toward edge computing, where heavy AI workloads shift from remote data centers to personal devices. It positions Perplexity against rivals who primarily rely on cloud-based processing for AI reasoning and agentic tasks.

Pro, Max, and Enterprise subscribers with high-spec Apple silicon Macs can now perform AI-driven planning and file processing offline. This improves workflow privacy, as users maintain complete control over when their local files are sent to the cloud.

The takeaway

Moving AI processing to the local machine offers a balance between advanced intelligence and enhanced privacy. Power users should ensure their hardware meets the specific memory thresholds before attempting to run local-first models.
