Health Copilot Live · continuous · private by default

Your body, translated.
Every beat.

Health Copilot reads the continuous signal from your BioSense Watch, Ring, and Band — and turns it into quiet, useful awareness. Reasoning runs on BioCortex v3.0, Vyvo's 4B-parameter clinical model. Not alarms. Not scores. Just context, exactly when it's useful.

The model inside

Built on a model that
actually studied medicine.

Meet BioCortex v3.0 — a 4-billion-parameter clinical model fine-tuned on a foundation pre-trained across medical text, de-identified chest X-rays, dermatology, ophthalmology and pathology. We pair it with a thin biosignal adapter that translates ECG / PPG / HRV windows into language the model can reason over.

BioCortex v3.0

Vyvo's health intelligence engine

Architecture: 4B-parameter instruction-tuned multimodal LM. Vision encoder handles medical imagery; a Vyvo-trained biosignal adapter fuses ECG / PPG / HRV into the same embedding space.
Pretraining: Inherits a foundation trained across medical literature, de-identified radiology, dermatology, ophthalmology and pathology — then fine-tuned on Vyvo's de-identified biosignal corpus.
Personal to you: Learns your baseline in ~72 hours from readings your device encrypts and forwards. Readiness is graded against you, not a crowd.
Where it runs: In Vyvo's private cloud. At 4B parameters it's too large for a wristband — the band handles capture & encryption, BioCortex does the reasoning.
Privacy: Raw signal is encrypted on the PoSe chip before it leaves your device. You control what's retained, what's shared, and what's deleted.
Grounded, not generative: Every nudge cites the feature it's reacting to. No free-form medical advice — just calibrated context.

Why this matters for you.

01
Reads medicine, not just metrics.
Pretrained on medical text and imaging before it ever saw a biosignal — so it reasons with clinical context, not just thresholds.
02
It knows you.
After a couple of days it has a map of your personal rhythms. Your readiness score is graded against you — not a population average.
03
Calibrated, not guessing.
Every inference carries a confidence band. Low confidence → Copilot stays quiet. High confidence → it surfaces a gentle nudge.
04
Your data stays yours.
Raw signal is encrypted on the PoSe chip before it leaves your band. You control retention, sharing and deletion — end to end.

How it flows

From heartbeat to helpful nudge —
without your data ever leaving you.

Signal is captured at the skin, encrypted on the PoSe chip, then reasoned over by BioCortex v3.0 in Vyvo's private cloud. Only the summary reaches the Copilot — and only the insights you opt-in to share.

What it watches

Seven signals, one coherent picture.

Heart rate & ECG

Clinical-grade electrocardiogram from curved-glass electrodes. Resting, active, and recovery trends — flagged when they drift from your baseline.

HRV & stress

Your nervous-system balance, measured continuously. Context, not a single overnight number.

AFib monitoring

Continuous atrial fibrillation detection — alerts you the moment an irregular rhythm is picked up.

SpO₂ & breath

Nightly oxygen saturation and breath rate — checked against your own baseline, not a global average.

Sleep stages

REM, deep, light, and disturbances — with a bedtime suggestion that actually follows your rhythm.

BIA body composition

19 measurements of fat, muscle, water, and cellular health — from the curved electrodes on your wrist.

Energy & readiness

A calibrated score — updated hourly — for when to push, and when to rest.

Air quality

World-first wrist-level AQI — the air you're breathing right now, refreshed every 10 minutes.

Your body, translated. Every beat.
