l3ms app icon: violet Mac display with an offline cloud symbol and a spark

Run local AI on your Mac.
The models your hardware can actually handle.

l3ms looks at your Mac, tells you which local LLMs will run well on it, and handles download and inference. Everything stays on your machine. No cloud. No account. No guessing.

Free during early access. macOS 13 or later.

How it works

  1. 1. It checks your hardware

    l3ms reads your Mac's chip, memory, and GPU headroom.

  2. 2. It recommends a model that fits

    Not the biggest model. The model that runs well on your machine, with an honest speed and quality tradeoff.

  3. 3. You download and run

    One click. Inference runs locally through ollama, streaming responses with no uploads.

Why local

Private by design

Your prompts never leave your Mac. No cloud, no account, no data collection.

Matched to your hardware

Get a recommendation that respects what your machine can actually do, instead of trial and error.

Works offline

Once a model is downloaded, you can use it without an internet connection. The cloud symbol in the icon is crossed out on purpose.

Frequently asked questions

What is l3ms?

l3ms is a macOS app that manages local LLMs. It looks at your Mac's chip, memory, and GPU headroom, recommends models that will actually run well on that hardware, and handles download and inference for you.

Does l3ms send my data anywhere?

No. Prompts and chat history stay on your Mac. Inference runs locally through ollama, and there is no account and no cloud component.

Which Macs does l3ms support?

macOS 13 or later. Recommendations adapt to your actual hardware, so an 8GB M1 gets honest suggestions, not the same list as a 64GB M3 Max.

How is l3ms different from ChatGPT or other cloud AI?

Cloud AI sends your prompts to a server and stores them. l3ms runs models on your own hardware, works fully offline once a model is downloaded, and needs no account.

Does l3ms cost anything?

It is free during early access. Donations are welcome. The app is part of a larger suite of local, offline-friendly apps from AIVI AI Services, an AI consulting firm in Amsterdam.

Do I need technical knowledge to use it?

No. l3ms tells you which model fits your Mac and handles the download. The chat interface is a regular app window, no terminal needed.
