Your devices
Your watch, scale, cuff, and any monitors you own. You connect each one a single time. After that they sync on their own — there's nothing to open or remember.

How it works · early beta
Connect your devices once.
Connect your devices once.
It does the rest.
Ilfirin reads the wearables and meters you already use — pulled directly to your own machine and shown in one place — and you coach with it through a normal Claude chat. No spreadsheets, no new app to learn, and your records stay in files on your own computer.
An early, invite-based beta. We say so plainly — that honesty is the point.
Works with what you already wear
The devices you use, pulled to your own machine.
Connect each device once and Ilfirin pulls it straight to your computer, then shows them in one view — no manual entry for most of what matters. Today that's Fitbit and Google Pixel (via Google Health), Withings scales + BP, and Garmin (community-supported). Whoop and Oura are easy to add. Apple Watch and CGM aren't supported yet — we say so plainly rather than imply otherwise.

One view
Most
of the passive signal — heart rate, sleep, steps, recovery — read for you, with no forms to fill.
Linking happens once, then it's passive: a daily pull keeps your watch, scale, and meters in sync without you lifting a finger.
The shape of it
Three layers, in plain language.
Nothing exotic: your devices feed a small program on your own computer, and you talk to that program through a chat you already know.
Ilfirin, on your computer
A small program runs on your own machine. It pulls your devices into one normalized view, finds the well-studied signals most apps ignore, and keeps your records — locally. There's no Ilfirin account and no company server.
Reads your data · never sends it anywhere on its own
You, through a Claude chat
No new app to learn. You chat in plain language — and Ilfirin answers from your own data, citing its sources. The dashboard is for looking; the chat is for doing.
"how am I today?" · "plan next week" · "log breakfast"
What's automatic, what's you
Most of it just happens. The rest takes seconds.
Most of the day-to-day signal — heart rate, sleep, steps, recovery — is captured automatically by your devices. The rest — food, bloodwork, and how you actually feel — you handle in a normal chat, no forms.

The dashboard · show, don't tell
All of it, in one glanceable view.
Everything above lands here — five domains, the signals most apps miss, this week's plan. It's read-only: every action happens in the chat. And there's no composite "longevity score," because components matter and single scores mislead.
Sample dashboard for an anonymized user. Status colors always carry a text label.
Where your data lives
It runs on your computer. Your data stays there.
Privacy here is by architecture, not by promise. The dashboard and your records live on your own machine — there's no Ilfirin account and no company database of your health data.
The honest part
- localYour records and dashboard live on your machine. We own no servers and keep no copy — there's nothing for us to sell or leak.
- honestDuring a chat, tool results pass through Anthropic — that's how Claude reads your data to coach you. We link Anthropic's privacy policy and don't pretend otherwise.
- 3 modesStandard for best quality, aggregated for summaries-only, or local-only to keep everything on your machine. Your call, anytime.
- no accountNo sign-up, no analytics following you, nothing sold. Plus a local audit log of every data access, readable any time.

Tell us a little about your devices and your setup. We'll provision your own instance and send you a personalized installer — no terminal required. It's an early, invite-based beta, and access is limited while we keep it small.
An early beta — not a finished, polished product, and not pretending to be.
