Clinician-governed · Consent-based · On WhatsApp
A health twin that knows you — and knows when to call a human.
TwinSelf builds a living picture of your health from your wearables, your bloodwork and your history — then keeps you on track right inside WhatsApp — no new app to learn — with clinical governance built into the system from day one.
We don't diagnose. We link, nudge, and keep people healthy.
Re: Right knee pain, running-related — assessment request
Presentation: Dull ache 5 days, mild swelling, no clicking, worse descending stairs (6/10), eases with warm-up. Onset after Sunday's padel. Not settling.
Context: Training load +18% week-on-week; HRV down 18% over 3 days with shortened sleep — recovery not keeping pace with load.
Patient consent: Given 07:09
— Shared by TwinSelf on the patient's behalf
The safety spine
Every message passes through clinical governance.
The twin responds to you directly, always. Behind it sits a clinical governance layer — oversight designed into the system, with clinician review that scales as we grow — and each interaction is classified by the degree of human attention it warrants.
Autonomous
Within a clinically defined scope — wellbeing guidance, interpretation, and day-to-day support — the twin operates on its own. No human attention required.
Flagged for oversight
The twin responds as usual, and the interaction is logged and surfaced for clinical review. The team may follow up, at their discretion.
Highest priority
When the twin identifies something serious, it stays with you, responds, and points you toward appropriate care. The interaction is marked highest-priority for clinical oversight.
How it works
No new app to learn. TwinSelf lives where you already talk.
Link your health data
Connect the wearables you already own — and share bloodwork or history when you choose to. The fuller the picture, the better the twin.
Message it on WhatsApp
Your twin lives in WhatsApp — no new app to download. It tracks your trends, answers questions, and nudges you on sleep, recovery, training and daily habits.
Referral, only with consent
When something genuinely needs a professional, the twin asks first — then, with your consent, shares a short summary with a registered clinician. A separate step, always your call.
Your data, treated like it matters
TwinSelf is built by a registered company and handles your health information as sensitive personal data — because it is.
What we collect
Wearable metrics, the health information you share in conversation, and documents you choose to upload — with your explicit consent, for the sole purpose of running your twin.
How AI is used
Your data is de-identified before any AI processing, and clinical oversight governs anything clinical, under a registered health professional. The twin advises on wellbeing; it does not diagnose.
Where it lives
Your records are stored in secure, encrypted infrastructure. We don't sell personal information, and we don't share it except as set out in our privacy policy.
Your control
You can request access, correction or deletion of your information at any time by writing to privacy@mytwinself.com.
Get in touch
TwinSelf is in a limited early pilot. If you'd like to take part — or you're a clinician, partner or wearable platform who wants to talk — we'd like to hear from you.
