Short answer: if you want an offline AI on a Mac and you enjoy the command line, use Ollama or LM Studio — they are free and excellent. If you want the same privacy as a finished, drag-to-Applications app with document reading and voice built in, from a company you can hold accountable, use SecureOffline. Everything below is the reasoning.
A word on bias: SecureOffline is our product. We have tried to make this the roundup we would want to read ourselves, which means naming the free alternatives clearly and conceding where they are better. If a free tool is the right fit for you, we would rather you use it than buy the wrong thing.
What "offline AI" actually requires
An offline AI app has one job: run the language model on your Mac's own chip, so the app keeps working with Wi-Fi off and your prompts never leave the machine. Every app below does that for the AI itself. Where they differ is in setup effort, what is built in (documents, voice), who stands behind it, and whether you can verify the "nothing leaves" claim. All of them need an Apple Silicon Mac (M1 or newer) to be genuinely useful; Intel Macs are too slow for current models.
The roundup at a glance
| App | Price | Setup | Reads your PDFs | Voice in / out | Best for |
|---|---|---|---|---|---|
| SecureOffline | $59 once (Personal); Professional plan for client work | Drag to Applications | Built in | Built in | Professionals with confidential documents; anyone who wants it to just work |
| Ollama | Free, open source | Terminal, or its simple desktop app | Needs a separate front-end | No | Developers and tinkerers |
| LM Studio | Free | Download, then pick a model yourself | Yes (attach files in chat) | No | Exploring many models with a GUI |
| GPT4All | Free, open source | Download, then pick a model | Yes (local document collections) | No | Open-source purists who want doc chat |
| Jan | Free, open source | Download, then pick a model | Limited | No | A clean chat UI over open models |
1. SecureOffline — best for professionals and anyone who wants a finished product
SecureOffline is a complete offline AI assistant for Apple Silicon Macs: chat, PDF reading, dictation, spoken answers, and PDF export, with no account and no setup beyond picking a model size. It is Apple-notarized, published by OnyxLinc LLC (a US company), and makes no network connections during use — which you can confirm with any network monitor.
It ships a curated set of Qwen 3 models (1.7B, 4B, 8B) sized to your Mac's memory rather than a catalog of hundreds. That is the trade-off: less choice, no tinkering. The Personal edition is $59 once; a Professional plan adds longer document reading, profession-specific template packs, and priority support for client work. There is a free 7-day trial and a 30-day money-back guarantee.
Where it loses: if you want to swap in any model on the internet, run a local API server for your own code, or pay nothing, the tools below are better. Frontier cloud models also remain more capable at open-ended reasoning than any model that fits on a laptop — that is true of every app on this list.
2. Ollama — best for developers and tinkerers
Ollama is a free, open-source tool that downloads and runs open models from the command line, with a large model library and a local API that other software can call. It is the backbone of a lot of the local-AI world, and if you are comfortable in a terminal it is the fastest way to try a new model the day it comes out. It now includes a simple desktop chat window on Mac as well.
Where it loses: out of the box it is a model runner, not an assistant. Reading PDFs, voice, and a polished chat interface mean adding a separate front-end (Open WebUI, AnythingLLM, and others), which is where the "afternoon of setup" usually goes. The ecosystem is excellent, and it is a project you maintain yourself — model updates, front-end updates, and the occasional breaking change.
3. LM Studio — best free GUI for exploring models
LM Studio is a free desktop app that lets you browse, download, and chat with open models through a graphical interface, and it can attach documents to a chat. For someone who wants to compare a dozen models without touching a terminal, it is the strongest free option on Mac, and it can also run a local server for developers.
Where it loses: you still choose the model, the quantization, and the context settings yourself, and the interface is built for people who want those knobs. No voice. It is a tool for exploring local AI more than a finished assistant for a specific job.
4. GPT4All — best open-source option with document chat
GPT4All (from Nomic) is a free, open-source desktop app with a built-in feature for chatting with folders of your local documents. That "local docs" capability is its standout, and being fully open source means anyone can inspect exactly what it does.
Where it loses: smaller model selection than LM Studio, a plainer interface, and the same self-serve model choices. Like the other free tools, there is no company support line if something breaks.
5. Jan — best for a clean, ChatGPT-style interface over open models
Jan is a free, open-source app that gives open models a familiar chat interface and can run entirely offline. If your main complaint about local AI is that it looks like a developer tool, Jan is the answer to that.
Where it loses: document and voice features are limited compared with the apps above, and it is still a pick-your-own-model experience.
What about the offline-AI USB sticks?
There is also a category of physical gadgets sold online that promise private AI on a USB stick. The idea is right; the delivery is where it struggles — shipping waits, no trial, and often an anonymous seller. We covered it in detail in our honest look at offline AI USB sticks.

- "I enjoy this stuff and want to pay nothing." Ollama, and add a front-end when you want documents. You will be happy.
- "I want to try lots of models with a GUI." LM Studio.
- "I want everything open source, including document chat." GPT4All.
- "I have confidential documents, a job to do, and no interest in a side project." SecureOffline. Try it free for 7 days with the Wi-Fi off and judge it against that bar.
Verify any of them the same way
Whichever app you pick, the privacy test is identical: open a network monitor, use the app, and watch what leaves your Mac. For the AI itself, every app on this list should show nothing — that is what offline means. Some apps still contact the internet for update checks or model catalogs, so look at what is being sent, not just whether anything is. SecureOffline is built to show zero during use; we would encourage you to check rather than take our word for it.
Frequently asked questions
What is the best offline AI app for Mac?
It depends on who you are. For developers and tinkerers, Ollama (free, open source) is the best offline AI for Mac. For a free graphical app to explore many models, LM Studio. For professionals who want a finished assistant with PDF reading and voice built in, from an accountable US company, SecureOffline ($59 once, free 7-day trial).
Is there a free offline AI for Mac?
Yes. Ollama, LM Studio, GPT4All, and Jan are all free and run open models entirely on an Apple Silicon Mac. They require you to choose and manage models yourself, and document or voice features usually need extra setup. A paid app like SecureOffline trades that flexibility for a finished, supported product.
Does offline AI on a Mac work with no internet at all?
Yes, once the model is downloaded. All the apps in this roundup run the AI on the Mac itself, so chat works with Wi-Fi off. The one-time model download (roughly 1 to 5 GB) needs a connection.
What Mac do I need for offline AI?
An Apple Silicon Mac (M1 or newer) with at least 8 GB of memory. More memory lets you run larger, more capable models. Intel Macs are too slow for current local models to be practical.
Is SecureOffline better than Ollama?
Not for everyone. Ollama is free, open source, and far more flexible about which models you run. SecureOffline is a finished app: drag to Applications, PDF reading, dictation and spoken answers, Apple-notarized, with support and a refund policy. Choose Ollama if you want a project; choose SecureOffline if you want the outcome.
Private AI that works even when the internet doesn't
