Local AI on Mac.
Local AI means the model runs on the machine in front of you. On an Apple Silicon Mac, that is not a compromise — the Neural Engine, GPU, and unified memory are enough to run real intelligence without sending a single byte to a vendor. NeutronTech builds software that assumes this by default.
Apple Silicon, not a data center
M-series chips share memory between CPU, GPU, and Neural Engine. A model can read the same buffer the renderer writes to, so inference happens where the data already lives — no upload, no round trip.
Offline by default
Core intelligence runs with the network off. Airplane mode, an air-gapped clinic, a locked-down enterprise laptop — the behavior is identical because nothing was outsourced.
Sovereign by construction
Sovereign intelligence means the owner of the hardware is the owner of the data and the model run. There is no vendor console holding your prompts, no retention policy to trust.
No metered inference
On-device inference has no per-token bill. Cost is the hardware you already bought, which changes what you are willing to run continuously in the background.
Cloud AI versus on-device AI
The difference is not model quality. It is who holds the data, who holds the switch, and what happens when the network is gone.
| Cloud AI | Local AI on Mac | |
|---|---|---|
| Where the model runs | Vendor GPUs | Your Mac's Neural Engine and GPU |
| Data leaving the device | Every request | None required |
| Works without internet | No | Yes |
| Marginal cost per use | Per token or per seat | Zero |
| Who can revoke access | The vendor | You |
What we run locally today
Three products, all Apple-native. No Windows, Linux, or Android builds — the architecture depends on Apple Silicon.
Nurse Neutron
Air-gapped clinical intelligence for the Mac, running MedGemma entirely on device. Shipping today on the Mac App Store.
DownloadHubyn (HBM)
Private messaging, calls, and workspaces with local transcription and a local assistant, built around a Hubyn PIN instead of a phone number.

A fully local AI workstation for the Mac you already have. One agent, Jimmy, routes your work to the right bundled model automatically on the shared Neutron Engine foundation — no setup, nothing leaves your machine.

Every cloud assistant is a standing dependency: a subscription that can be repriced, a policy that can change, a log you cannot inspect. For regulated work — clinical, legal, defense, anything under a data residency rule — that dependency is often the blocker, not the model.
On-device intelligence removes the dependency instead of insuring against it. The model ships with the app, the inference happens in your memory space, and the audit answer is simply that nothing left the Mac.
