Perplexity's Computer can now run entirely on your Mac, even with no internet connection
A new local mode in Perplexity's Mac app runs both the model and the agent on the computer itself, and only sends files to the cloud when the user approves it.
Perplexity has launched a local mode in its Mac app that lets Computer, its task-running assistant, work entirely on the device, even with no internet connection. The company announced the feature on October 20, and it is already available in the app.
As 9to5Mac senior editor Zac Hall reports, the update follows Hybrid Compute, which arrived in September. That feature splits the workload: cloud models handle research and reasoning, while a local model deals with private files.
Local mode goes further. Both the AI model and the agent carrying out the task run on the Mac. According to Perplexity, planning, reasoning and file processing can all happen on the device, and files only reach the cloud when the user approves.
What the assistant does on the device
With permission, Computer works with local files and with compatible Mac apps, including Notes, Messages, Mail and Numbers. In the announcement, the company summed up the pitch this way: "The model and the agent run on your Mac."
One example Perplexity gave is reviewing recent messages and emails, spotting deadlines and building an action list in Notes.
Users can still grant cloud access when a task needs up-to-date information, browser use or connected apps. Hybrid Compute remains available in the same app.
Who can use it
Local mode is open to subscribers on the Pro, Max and Enterprise plans. It launches with two local model options, Qwen 3.6 and PPLX Pro, which users download and set up directly in the app.
For the best experience, Perplexity recommends a Mac with Apple silicon and at least 36GB of unified memory.
What this means for brand teams
In local mode, Perplexity's assistant works with the user's own files and apps, without relying on the internet. When a task calls for current information or browsing, it is the user who unlocks cloud access. In practice, searching the web becomes a step the person signs off on, rather than the starting point of every task.
