Neither extreme is quite right — it's not a doctor, but it's also not useless, if you know what it's actually good for.
1. Fine for: understanding a term your doctor used, getting a plain-language overview of a condition, preparing questions to ask a real provider, general health literacy.
2. Not fine for: diagnosing a specific symptom, deciding whether something is an emergency, dosing medication, replacing an actual exam. AI tools don't have your history, your labs, or the ability to actually examine you, and they can sound confident while being wrong.
3. Treat any AI health answer as a draft for a conversation with a real provider, not a conclusion — bring the question to them rather than the AI's answer as settled fact.
4. If something feels urgent, that's a sign to call a nurse line or go to urgent care, not a sign to ask a chatbot for reassurance.
Used as a way to walk into a doctor's appointment better prepared, it's genuinely useful. Used as a replacement for the appointment, it's where the real risk is.
