# Citizen Health

> Citizen Health is a San Francisco-based AI health platform built for people living with rare and complex conditions. It pulls a patient's fragmented medical records into one place, turns them into a structured, queryable dataset, and layers on an AI advocate plus a peer community so patients, families, and clinicians can ask plain-language questions and find the next best step. Consenting patient data also powers research for pharmaceutical partners. The company grew out of Ciitizen, the patient-data startup acquired by Invitae, and relaunched independently in December 2023.
