Whoever you trust to know you, remember for you, and connect your whole life holds the most valuable ground in technology. Today that's the companies that profit from knowing you.
Arkhelion is the private alternative.
See it running
Open it in this browser tab.
The real interface, filled with one imagined person's record. No download, no account, nothing to set up. It opens in about a second.
Runs in the browser. Mac app is the real one.
- You'll see Every screen, laid out exactly as it is on the Mac.
- You'll see A made-up person's health record, labelled as made up on every screen.
- You won't get Answers. A browser tab can't do the thinking — that happens in the Mac app, on your own key. Ask it something and it tells you so, instead of inventing a reply.
- You won't leave Anything behind. Nothing you type is saved, because there's nowhere in a browser tab for it to go.
Free, no account
Check the days before your worst days.
Most trackers only compare today to today. If it started two days earlier, they find nothing. This reads a spreadsheet you already have and looks backwards. It runs in your browser, and your file is never uploaded.
Nothing to install. Nothing to sign up for.
Where it's going.
It begins where care fragments: every doctor seen, still no clarity. It grows into an intelligence for a whole life.
- Today A private command center on your Mac.
- Next On your phone. Noticing what matters while you aren't.
- In time Open only to the tools you choose. Never given away.
Why Arkhelion exists
Your life is scattered across apps that don't talk. Each sees a slice. None sees you.
You've spent years piecing your own history together, one appointment at a time.
Nothing connected it. This connects it.

What it notices
The pattern shows up before the week is over.
This is the first card the app shows in the morning. Nobody asked it a question — it went looking through the record on its own, and it says where the finding came from and how sure it is. It is not a verdict on how you spent your week. It is something to watch while there is still time to act on it.
First Read, marked Keyless · Local. Demo data shown.
“I watch it so I can pace myself.”
The example record's own note, beside the finding. The card prints its own hedge underneath the pattern: a correlation, not causation, and not medical advice. It is not a verdict on how anyone spent their week.
What it remembers
You logged them weeks apart. It put them together.
Migraine, six times between 25 July and 13 August. Pain, five times, scored out of ten. Brain fog, four times. You entered those one at a time, on days that felt unrelated. The trail is the part you can never hold in your head — and the part a doctor asks for in the first two minutes.
Trail, marked Recurrence · Local. Demo data shown.
What you can ask it
One line at the bottom of everything.
Ask it anything about your own record. On the Mac, the answer comes back from a model running on a key you supply. It is off unless you turn it on; when it is on, the AI provider is shown the part of your record that bears on your question.

The only intelligence that connects your whole life. Behavior, body, and calendar, not just lab tests. It sees patterns coming, works only for you, and stays entirely yours.
