Early, invite-based beta

Request access to the beta.

Ilfirin is a personal longevity coach that runs on your own computer and reads your health data locally. The beta is small and hands-on — we set up your instance with you, then hand you the keys.

The request

Tell us a little, and we'll be in touch.

A few questions, not a sign-up. There's no account to create — we read this, reply by email, and set up a personalized installer for your machine.

Name

Primary wearable

Once you're set up, Ilfirin reads the devices you already use — Fitbit, Pixel, Withings, and Garmin today, with Whoop and Oura easy to add. This just tells us where to start.

What do you want from it? (optional, but it helps)

No wrong answer. It helps us judge fit and tailor your onboarding.

We email you back. No account, no newsletter, nothing sold.

What happens next

Three steps, no surprises.

We read your request and reply.
A real person, by email. If the beta's a fit for your setup, we'll say so plainly — and if it isn't yet, we'll tell you that too.
We set up your instance together.
We provision a personalized installer for your machine — your subdomain, your allowlist — and walk you through it. Not one-click; we don't pretend it is.
You connect your devices once.
Link them once and Ilfirin reads them all in one place. From then on, you just talk to it in a normal Claude chat.

Honest framing

What this is — and isn't.

Beta
An early, invite-based beta. Hands-on by design — not a polished consumer app, and not pretending to be one.
Local
Runs on your own computer. Your health data stays on your machine. Honest caveat: during a chat, tool results pass through Anthropic so Claude can read them.
Yours
No account, no company database. Nothing about you is stored on our side or sold. Three privacy modes let you decide how much ever leaves the machine.

One normalized view

Connect once. It reads the devices you already use.

Once you're set up, it pulls your devices straight to your own machine — one place for everything, no manual entry for most of the day-to-day signal. Your device above just tells us where to begin.

Fitbit Google Pixel Withings · scale + BP Garmin · community Whoop · addable Oura · addable Apple / CGM · not yet

Most of the passive signal — heart rate, sleep, steps, recovery — read for you, no daily form-filling.

The remaining slice — food, bloodwork, how you actually feel — you handle in a quick chat, not a spreadsheet.

Rather just write to us?

Email works too.

Skip the form and tell us about yourself in your own words. Same inbox, same real reply — whatever's easiest for you.
