Perplexity Computer local mode is now live for Mac users on Pro, Max, and Enterprise plans. It lets the AI agent plan, reason, and handle your files entirely on your own machine, with no cloud round trip unless you allow one. If you’ve been wary of handing your email and messages to a cloud AI, this is the version built for you.
Here are the quick facts, so you can skim and decide whether to read on.
- Launched October 20, 2026, for Perplexity Pro, Max, and Enterprise subscribers.
- Runs on Apple silicon Macs through the latest Perplexity Mac app.
- Perplexity recommends at least 36GB of unified memory (a recommendation, not a hard minimum).
- Local models at launch: Qwen 3.6 and PPLX Pro, Perplexity’s own post-trained Qwen.
- Cloud access is optional and can be switched on per task.
What Perplexity Computer local mode actually does
Perplexity Computer is an AI agent that does tasks for you, not just answers questions. With your permission, it can work across Notes, Messages, Mail, and Numbers. A typical job: read your recent threads, spot deadlines, and build an action list in Notes.
That mix of apps is what makes it useful day to day. Your own messages and mail are exactly the data many people don’t want in someone else’s data center.
The new part is where the thinking happens. Planning, reasoning, and file processing stay on your Mac. Code and tool actions run inside isolated sandboxes, and Perplexity says the cloud version has the same protections.
This follows Perplexity’s earlier Hybrid Compute option, which was cloud-first and used local models only for private data. Local mode flips that default. You can pick local or hybrid for each task inside the same app.
How to turn it on
Setup is short, according to TBreak’s launch coverage. You do three things:
- Update the Perplexity Mac app to the latest version.
- Download a local model inside the app.
- Choose the fully local option when you start a task.
The model download is the slow bit, so do it on a good connection before you need it.
Which Macs can handle it?
Memory is the deciding factor. Local models live in unified memory, so the more you have, the smoother the agent runs. AppleInsider’s breakdown of current Macs against the 36GB recommendation looks like this:
| Mac | Memory | Meets 36GB advice? |
|---|---|---|
| Standard M6 Mac mini | Up to 32GB | No |
| M5 Pro Mac mini | 48GB or 64GB | Yes |
| M5 Max Mac Studio | Starts at 36GB | Yes, no upgrade needed |
| Older Apple silicon Macs | Varies | Yes, if they have enough memory |
Because 36GB is a recommendation, a smaller Mac may still run it, just slower or with limits. Perplexity hasn’t published results for full Computer workflows across different configurations, so treat low-memory setups as a test, not a promise.
If you like running models on your own hardware, our look at Recursive Flint, a 40B coding model for a 48GB Mac shows how much memory matters for local AI in general.
Where local mode still needs the internet
“Fully local” doesn’t mean “offline for everything.” Sending an email or using an online service still needs a connection. And if you want current information, browser use, or connected apps, you have to allow cloud access.
When you do, the local agent can call one of more than 15 frontier models for harder reasoning. That’s a handy escape hatch, but it also means some data leaves your Mac. Decide per task, and keep sensitive jobs on local only.
Local also isn’t a magic security shield. AppleInsider notes that mishandled files or malicious instructions hidden in documents are still risks. It also points out that Perplexity hasn’t said whether the agent needs Full Disk Access, which Apple plans to tighten. For a wider view of this trend, see our piece on hybrid intelligence PCs.
Frequently Asked Questions
Is Perplexity Computer local mode free?
No. It’s available to Pro, Max, and Enterprise subscribers. Perplexity also pitches local mode as a way to control credit spend, since local tasks don’t burn cloud resources.
Do I need 36GB of memory to use it?
Perplexity recommends 36GB or more, but says it isn’t a strict minimum. Expect better results on 48GB or 64GB machines.
Does it work on Intel Macs or Windows?
Local mode targets Apple silicon Macs. Perplexity has a separate Portable Computer product for Windows RTX PCs, according to TBreak.
Is my data really private?
Planning and file processing stay on your Mac in local mode. Anything you send through cloud access, such as web lookups or frontier models, does leave the device.
My take: if you already own a Mac with 36GB or more, try local mode on one low-risk task, like sorting your Notes into an action list. Keep cloud access off until you’re happy with the results. If you’re buying a Mac mainly for this, wait for real-world benchmarks, because Perplexity hasn’t shown how the full agent performs across different configurations yet.
