AI Health Apps: Checking Symptoms and Preparing for Doctor Visits

AI health apps are phone or web applications that ask you questions about symptoms you are experiencing and then give you information about what might be going on and whether you should seek medical care. They are not a replacement for seeing a real doctor — but they can help you feel more prepared and informed before, during, and after a medical appointment.

The most well-known free AI health assessment app is Ada Health, available at ada.com. You describe your symptoms — for example, a headache that started two days ago, along with some nausea — and Ada asks follow-up questions the way a doctor might. It then gives you a summary of possible explanations, ranked by likelihood, along with a recommendation about the level of care you might need (such as "see a doctor soon" or "self-care at home may be appropriate").

Another option is Buoy Health (buoyhealth.com), which works similarly through a web browser without requiring an app download.

It is important to understand what these tools are and are not. They are decision-support tools — meaning they help you think through a situation, not diagnose you. They can be wrong. They may miss something important. They are most valuable for helping you figure out whether something warrants a doctor visit, for preparing a list of symptoms to describe accurately to your doctor, and for understanding possible explanations for what you are feeling.

These apps are not appropriate for emergencies. If you are experiencing chest pain, difficulty breathing, sudden severe headache, signs of stroke (face drooping, arm weakness, speech trouble), or any other potentially life-threatening situation, call 911 immediately.
