chanio on a Mac

Your intelligence, on your own device.

chanio keeps what you think through with AI as plain files on your Mac, and a small AI on the same Mac answers from them and writes you a summary each morning. Your chats still happen in the cloud; your notes and the summary stay at home, not in a cloud that “protects” your memory by keeping it.

What runs: the starter, on a Mac with macOS 14 or newer, with its small AI in Ollama; the nightly pass runs on your Mac. What was tested: in July 2026, one step, answering from the memory pack, ran on Apple's own model, on the Mac itself. The starter does not use Apple's model.

Your AI chats → your Mac → overnight → a summary by morning. It runs on a Mac, with a small AI in Ollama.
01 · The loop, end to end

What you save from your AI, working for you while you sleep.

Seven beats, as the starter runs them on a Mac. Most of the work happens while you sleep: you use your AI, and a summary is waiting in the morning.

01
You use your AI
Claude, ChatGPT, Gemini, whatever you already pay for. Nothing changes about how you work.
02
You save what matters
Paste a chat or an article into chanio and it is saved as a plain file on your Mac, next to your own notes.
03
The small AI answers from your notes
It shows the lines it drew on. When your notes don't settle a question, it keeps the question for tonight instead of guessing.
04
It works overnight
At 5 a.m. the small AI reads the day's notes on your Mac. The questions you kept go out in one batch only if you have added your own Claude key.
05
A morning summary
A note on your Mac each morning: what mattered, the threads still open, and the questions worth asking.
06
Your aims, next to what you did
Write what you are aiming at in focus.md. chanio reaim sets each aim against the last 14 days of your notes: active, present, or quiet.
07
The next AI you open can start with you
Your aims and a week of summaries, in one memory pack under 6 KB. Hand it over and the AI starts from where you are; the rest stays on your Mac.
02 · Apple's pieces

What chanio has tested on Apple's own model.

One test so far: Apple's own model, on a Mac, answering from a memory pack (section 04). The starter does not use Apple's model; its small AI runs in Ollama. Tap a card for Apple's own documentation.

SystemLanguageModel
Apple's own model, built into the device. Tested in July 2026: chanio loaded a memory pack as its instructions and it answered on the Mac itself. The starter does not use it; its small AI runs in Ollama.

Private Cloud Compute
Apple's server model for requests too big for the device. Apple says request data is not kept, and it publishes the server software for outside researchers to inspect. chanio does not use it.

03 · Why your own machine is the whole point

The model is rented. The memory is yours.

Apple itself reportedly rents a bigger, outside model for Siri. Everyone runs the same commodity intelligence now — the value moved up, to the layer that remembers you and compounds. The cloud giants know it, so they all offer to “amplify and protect your intelligence.” Read the fine print: it lives inside their systems, and “protect” means a promise not to train on it.

chanio's rule is the opposite: your memory stays as plain files on your disk, and you decide what any model sees. A bigger AI you hand part of it to sees that part, like any chat. The overnight work runs where the memory already lives: the small AI on your Mac. No AI should eat the intelligence of the person it's deployed inside.

Apple's own Siri makes the point for us. It now keeps a memory on the device — but of your apps: the messages, mail, and photos Apple can see. It can't see the hours you spend thinking with Claude, ChatGPT, or Gemini, and its index is a black box you can't take with you. chanio keeps exactly that missing layer, as plain files you own. Siri remembers your apps. chanio remembers your thinking.

Sovereign
Your notes live on your Mac as plain Markdown files. They outlive any model.

Nightly, on your Mac
The nightly pass runs on the small AI on your Mac. Questions you keep go out only with your own key, under your daily spending limit, and the meter counts what left.

One Mac so far
The starter needs macOS 14 or newer. It has run on one Mac so far, the founder's, so expect rough edges.

Your files, your call
Your notes stay on your Mac; a bigger AI sees only what you send it. The privacy policy covers what this website itself collects.

04 · Where it is today

Running now, on a Mac.

This part is not a mockup. The starter runs the loop on a Mac today: saving what you paste, the small AI answering from your notes, the morning summary, and the memory pack. In a July 2026 test a memory pack ran on Apple's own model, through the runtime Apple ships in macOS 27: fm respond, with the memory pack loaded as its instructions. In about five seconds, on the Mac itself, it answered a grounded question about the person, citing what they care about and keeping them to their own rules. We ship neither the model nor the runtime; Apple does, inside the OS. That test covered one step, the answer; the starter's small AI runs in Ollama.

On a Mac, the starter sets up this loop today. It has run on one Mac so far, so expect rough edges.

The same idea for health alerts is Harness Health’s Pocket: a prototype, not released, where your iPhone and your Mac keep the heart-rate readings and fixed rules set the urgency.
