Ubie
Free AI symptom checker that builds a report on possible causes and when to see a doctor.
About
Ubie is a free AI symptom checker that walks users through a roughly 3-minute questionnaire on symptoms, age, sex, and medical history, then produces a report of possible causes, treatment information, and guidance on whether to seek care. The company says its AI is trained on 50,000+ peer-reviewed publications and supervised by more than 50 medical experts, and a vignette-based study it cites found accuracy competitive with physicians. Ubie reports more than 13 million monthly users globally, with over a million in the US, and its provider intake product is used by 1,800+ healthcare organizations in Japan.
Founded in Tokyo in 2017 and backed by Google among others, Ubie has raised over $125 million cumulatively, including a $26.2 million Series C in 2022, and entered a collaboration with Mayo Clinic in 2026. It is free for consumers and sells to insurers and pharma as a targeting platform. A symptom checker is a starting point, not a diagnosis: its output is informational, and the company itself directs users to professional care when findings warrant it.
