What is Buoy Health?

Buoy Health is an AI symptom self-check and medical treatment navigation tool for ordinary users. Founded by Dr. Andrew Le and others at Harvard Innovation Labs, it was established in Boston in 2014. Unlike general search engines that provide direct answers, it simulates a doctor's consultation logic through conversational question-and-answer, narrowing down possible causes of symptoms and providing triage suggestions with each question. Its core difference lies in clarifying "whether you should go to the hospital, which department to register for, and the priority of urgency," and it is accompanied by popular science content reviewed by clinical experts.

Who is it for?

Ordinary users who are feeling unwell but unsure whether to seek medical attention and want to clarify their symptoms first.
People with mild or chronic conditions who want to distinguish between "staying at home for observation" and "going to the hospital".
Employers and health insurance institutions that provide medical care navigation for their employees and members.
Readers who need reliable health science content and want to avoid exaggerated and misleading information.
Medical institutions and public health projects that want to embed preliminary triage into their own processes.

Key features

Symptom Checker Dialogue

After a user enters their discomfort, the AI selects the next question in real time based on the responses. The official states that it covers more than 1,600 types of diagnoses and about 30,000 interview questions, with training data sourced from 18,000 clinical papers and approximately 5 million patient records.

Smart Triage

Combines symptom severity and risk factors to recommend self-monitoring, general practice appointments, Urgent Care, or emergency care, and provides nearby healthcare access when needed to reduce unnecessary emergency department visits.

Clinically Reviewed Popular Science Content

Health articles and symptom guides are written and reviewed by doctors, clinicians, nurses, and therapists. The official states that the content is edited by experts, clearly presented and actionable, and supported by clinical research.

Rankings and Evaluations

The editorial team compiles Top 10 checklists and evaluations from third-party services or doctors, helping users compare options horizontally beyond AI and expert opinions.

Corporate Navigation Solution

It delivers navigation capabilities to health insurers, employers, and healthcare systems in the form of B2B, and officially states that its partners include institutions such as Cigna, Humana, and Optum.

How to use Buoy Health

First, clearly state your main symptom, then patiently answer the follow-up questions.
the more specific your input, the more accurate the triage suggestions will be, so don't skip details in the first step.
Treat it as a "self-check before seeing a doctor" rather than a diagnostic tool: The official states that its consistency rate with doctors' diagnoses in the first-round quality control test is about 90.9%, but it is only a reference and not a conclusion.
In case of emergency signs (such as chest pain, difficulty breathing, altered consciousness, suicidal thoughts, etc.), do not wait for the tool's conclusion.
seek medical attention immediately or call local emergency and psychological crisis hotlines.
For matters related to medication use, pregnancy, and chronic disease follow-up visits, the judgment of your attending physician shall prevail at all times.
the official clearly states that this tool cannot replace professional medical diagnosis.
Before corporate procurement, confirm the data ownership, retention and privacy terms.
for individual users, remember that its output does not constitute medical advice, and offline consultations are still required for major decisions.
