Perplexity has launched a local-first mode for its Mac application, allowing users to process AI tasks and files directly on their devices. This new feature runs reasoning and planning agents locally on Apple silicon Macs for Pro, Max, and Enterprise subscribers.
Why it matters
By moving processing from the cloud to local hardware, this update enables users to handle sensitive files within Notes, Messages, Mail, and Numbers without data leaving their machine unless explicitly approved. It represents an expansion of the company's focus on private, on-device computing following their September Hybrid Compute release.
The feature requires a minimum of 36GB of unified memory on Apple silicon Macs to operate. It supports Qwen 3.6 and PPLX Pro as local model options, marking a shift from the previous cloud-only architecture.
The players
Perplexity
An AI search and reasoning engine company that builds agents for information retrieval and file processing.
Apple
A designer and manufacturer of consumer electronics and the creator of the silicon architecture required for this local processing.
The details
The local-first mode enables AI reasoning and planning by executing language models directly on the machine's neural engine and GPU. Users manage model downloads and configuration through the app interface, which then hooks into system-level applications including Notes, Messages, Mail, and Numbers to index and process local files. Data stays local by default, with an approval prompt serving as the gatekeeper for any cloud-based relay.
Timeline
September 2026: Hybrid Compute technology was introduced.
October 20, 2026: The local-first mode became available in the Mac application.
The Tech Race
This development follows the September 2026 introduction of Hybrid Compute, marking the company's pivot toward decentralizing AI inference. It positions Perplexity against other local-model deployments by emphasizing deep integration into native OS applications.
Pro, Max, and Enterprise subscribers with Apple silicon Macs meeting the 36GB memory requirement can begin using the local mode immediately. The feature integrates directly into Mail, Messages, Notes, and Numbers to provide AI reasoning for personal and work documents.
The takeaway
The move suggests a long-term goal of building autonomous, private research agents that exist entirely on the user's desktop. Watch for further model compatibility updates that may lower the 36GB hardware barrier for broader user access.
