Buoy Health is an AI-powered symptom checker and health navigation tool that helps users understand what their symptoms might indicate and what level of care is appropriate. Users describe symptoms through a conversational interface, and Buoy's clinical AI asks follow-up questions to narrow down potential causes, providing information about relevant conditions and directing users to the appropriate care setting: self-treatment at home, a telehealth visit, urgent care, or emergency services. The tool was built by a clinical team with Harvard Medical School connections and trained on thousands of clinical decision pathways. It processes millions of symptom checks annually and is embedded into health system websites, insurance portals, and employer benefits platforms as a white-label care navigation solution. The clinical database covers over 800 conditions and is updated to reflect current medical guidelines. Buoy Health is free for individual users through the web interface. For healthcare organizations, insurers, and employers, it is available as a white-label platform embedded in patient-facing portals to reduce unnecessary ER visits while ensuring patients with serious symptoms are directed to emergency care promptly. It is particularly valuable for health systems looking to manage ED utilization.

What the community says

Generally positive among consumer health audiences who find it more reliable than searching symptoms on Google. Users appreciate the conversational format and clear care guidance over raw search results. Medical professionals and patient advocates note that AI symptom checkers including Buoy should complement rather than replace clinical evaluation. Criticism focuses on it being more conservative than users would like (directing to urgent care when self-care would suffice) and occasionally asking many questions before reaching guidance. Considered one of the more clinically rigorous free symptom checkers available.
