Perplexity is adding a new local-first mode to its Mac app that lets Computer work entirely on the device, including running tasks without an internet connection. The launch builds on Hybrid Compute, which arrived in September and splits tasks between cloud models for research and reasoning and a local model for working with private files.
Local-first goes further by running both the AI model and the agent directing the task on the Mac. Perplexity says planning, reasoning, and file processing can all happen on the device, with files reaching the cloud only when the user approves. With permission, Computer can work with local files and supported Mac apps, including Notes, Messages, Mail, and Numbers.
One example Perplexity gives is reviewing recent messages and emails, identifying deadlines, and creating an action list in Notes. Users can still authorize cloud access when a task needs current information, browser use, or connected apps. Hybrid Compute remains available in the same Mac app.
The new local mode is available to Perplexity Pro, Max, and Enterprise subscribers. It launches with Qwen 3.6 and PPLX Pro as local model options, which users can download and set up through the app. For the best experience, users need an Apple silicon Mac with at least 36GB of unified memory.
