Meet Citizen Health, A New Teammate For Your Diagnostic Journey

Big news for our community. UDNF has partnered with Citizen Health, and we want you among the first to take part.

Citizen Health was built for rare disease by people who live it, including co-founder Nasha Fitter, a rare disease parent. That lived experience shapes what they build: tools that make the daily work of care easier for families like ours.

Through this partnership, every undiagnosed family gets early access to Ari, a personal AI teammate for your diagnostic journey. It helps carry the daily work: pulling your records into one place, tracking symptoms, drafting insurance appeals, and prepping you for appointments. You text it like a friend, and it does the work.

Ari is in early access. It is new and still growing, and your feedback shapes what it becomes. You are not just getting a tool. You are helping build the next generation of rare disease care.
