One in Three Americans Now Use AI Chatbots for Health, Rock Health Finds

Overview

• Rock Health’s latest consumer survey, fielded in December 2025, reports 32% of U.S. adults have used an AI chatbot for health information, up from 16% a year earlier.
• Most people seek help from general-purpose tools rather than health system bots, with 74% using services like ChatGPT and Gemini, and brand shares led by ChatGPT at 23% and Gemini at 15%.
• Users act on what they learn, with Rock Health finding 81% took steps such as searching more, trying a new behavior, or contacting a clinician, and these users also track more health metrics and use more care.
• Privacy trade-offs are growing as AI users share sensitive data more readily with health tech and consumer tech firms outside HIPAA’s protections, which raises concerns about data rights and accountability when tools get things wrong.
• A separate Zocdoc survey shows 26% of patients now ask AI for medical advice, many hide that use from doctors, most clinicians view AI-informed patients positively, and many visits run longer as doctors correct misinformation.
