Kalon
Edge-Ready. Human Aligned.
A private, agentic AI that runs entirely on your Mac and iPhone.
Free for the Mac now, no account. iPhone and iPad are next.
On the Mac, an image from a service you connect. On iPhone, Gemma 3 1B, running on the device.
Get the highlights.
Maths and diagrams, drawn in the chat.
Formulas are typeset and SVG diagrams render in the reply, animations included, in a sandbox that cannot reach the network.
Sized to your memory.
Kalon reads how much memory the device has and fits the model to it. On an M1 Pro with 16 GB it allows up to 11.8 GB.
It tells you when it's ready.
Pick a model and a notice drops from the Dynamic Island. On the Mac, the notch shows the memory it takes.
One switch. No connections.
Turn on Block all network access, and Kalon makes no outbound connections, on the Mac and on iPhone.
Writes code, too.
Ask for a function and get it, explained, from a model on the phone in your hand.
A local API, on your terms.
An OpenAI-compatible server on port 11434, stopped until you switch it on.
Skills, in plain Markdown.
Recipes that make Kalon a specialist. Only their names sit in context until a task needs one.
How it works
What sets Kalon apart.
It runs on your device.
The model, your chats, memory and files stay on the Mac or iPhone in front of you.
Why Edge Intelligence
Intelligence where the network isn't.
Nearly one-third of humanity, 2.6 billion people, remains offline. Even connected regions face a fragile backbone: over 95% of international traffic rides subsea cables, and cloud reliance remains costly.
Kalon puts the model on the device in your hand. It answers without a round trip, keeps your data where you are, and keeps working when the network doesn't.
- 2.6B
- people, nearly one-third of humanity, remain offline.
- 95%+
- of international traffic rides subsea cables.
- 90M–1T
- parameter open-weight models, from a phone to a 512 GB workstation, each sized to the memory it has.
Privacy
Nothing leaves without your say.
Conversations, files and memory stay on the hardware you own. Online models stay off until you choose one, and a single switch stops every outbound connection.
- Data
- Conversations, files, and memory stay on your device.
- Remote models
- Optional, off by default. You choose the provider and the key.
- Backups
- Password-protected, AES-encrypted archives you can move between your own devices.
- Block all network access
- One switch stops Kalon's outbound connections, including model downloads, online models and realtime voice.
Products
One assistant. Two companions.
No network required for any of them. The long-term goal is one app: Air Kalon folds into Kalon first, AirLink follows.

Developers
Your tools. Your machine.
Point anything that speaks the OpenAI API at Kalon, and it answers from the model on your own hardware.
- OpenAI-compatible API served by the app on 127.0.0.1:11434
- Local network access is a separate switch
- MCP servers over stdio and HTTP
- Skills in plain Markdown, and plugin bundles

What people say
“The first assistant I trust with my real documents. They never leave the laptop.”
“No Wi-Fi on the flight, and I still got real work done. The pitch holds.”
“Sent a deck to a colleague's phone with the camera. No cable, no pairing, no cloud.”
“Running MCP tools locally, with no server in the loop, changed how I prototype.”
No. Models, tools, memory, and voice all run on the device. You only need a connection to download a model the first time, or if you choose to add a remote provider.
Intelligence on the device you already own.
Private by default, fast without a network, and free for macOS and iPhone.
