Tell us about you
Age, gender, ethnicity, and your primary condition. That's it. No account, no email, no waiting.
We build your group

Start talking
Each patient plays a unique role in your support group: your Mirror, your Veteran, your Navigator, your Ally, your Specialist.
Your support group
5 patients. 5 roles. All matched to you.
The Mirror
Someone exactly where you are. Same stage, same treatment, closest demographic match.
The Veteran
12-36 months ahead of you. Proof that it gets better. The hope narrative.
The Navigator
Managing your condition plus the most likely comorbidity. Expands what you know is coming.
The Ally
Same disease, different background. The cross-cultural bridge that proves you're not alone.
The Specialist
On your exact treatment. Shares the day-to-day of your specific therapy.
Why this works
Not another chatbot. A support group built for you.
Clinically grounded
Every patient profile is built from PrimeKG (Harvard), CDC NHANES, and leading hospital data. Not hallucinated. Cited.
Private by default
No account or credit card required. Your data is never sold. Your health data stays yours.
Demographically matched
Race, age, gender, insurance, geography. We match across 5 axes because health experiences aren't one-size-fits-all.
Equity-aware
CDC-documented health disparities are encoded, not ignored. Your group reflects real barriers, not average ones.
Mobile-first
Works on any phone, any browser. No app to download. PWA-ready for offline use.
Crisis-safe
5-tier crisis detection with immediate 988 Lifeline routing. Safety is a mandatory transition, not an optional branch.
Built on open science
Every synthetic patient links back to its source. No black boxes.

Important
An Experimental AI Community
While we have safety guardrails in place, this platform is an evolving work in progress and should be used at your own risk.
Not a doctor
Synthetic patients cannot replace a real healthcare provider, so please do not rely on them for medical information or advice.
AI hallucinations
AI health companions can sometimes hallucinate, meaning they may confidently invent and share false or inaccurate details.
