Free AI Symptom Checker

Free AI symptom checker: select your symptoms, add duration and severity, and get an instant medical AI assessment with an urgency level and advice on when to see a doctor.

Select your symptoms and get an instant, private assessment from a medical AI — no sign-up needed.

This tool gives guidance only and is not a medical diagnosis. In an emergency, call your local emergency number (911 in the US, 999 in the UK, 112 in Europe).

How the AI symptom checker works

Pick the symptoms you have from six body areas or describe them in your own words, then tell us how long you have had them, how severe they feel, and optionally your age and sex. The medical AI weighs common causes against red-flag signs and returns an urgency level (low, moderate, high or emergency), a short analysis of the most likely explanations, three practical tips, and clear advice on when to see a doctor. It takes about ten seconds and nothing is stored without an account.

What this symptom checker can and cannot do

  • It can help you decide what to do next: rest and monitor, book a GP appointment, or seek urgent care.
  • It cannot examine you, order tests, or replace a clinician who knows your history — treat the result as a starting point for a conversation with a doctor.
  • Severe chest pain, difficulty breathing, sudden weakness or numbness, confusion, heavy bleeding or a very high fever in a baby are emergencies: call for help before using any online tool.
  • Results depend on what you enter; the free-text box lets you add anything the checklist misses.

Is the AI symptom checker free?

Yes. Checking your symptoms is completely free and does not require an account or a card. A free account lets you continue in a chat with the AI doctor and keep a history.

How accurate is an AI symptom checker?

It is designed to sort symptoms by urgency and list the most common explanations, not to give a definitive diagnosis. Studies of symptom checkers show they are useful for triage — deciding how quickly to seek care — which is exactly what this tool focuses on.

Does it work for children?

You can enter a child's age and symptoms, and the AI will take the age into account. Babies under three months with a fever, and any child who is drowsy, struggling to breathe or not drinking, need a doctor straight away rather than an online check.

Is my data private?

Symptoms you enter are sent encrypted to the AI to produce the assessment and are not sold or shared. Without an account, nothing is kept once you close the page.

When should I go to the emergency room instead?

Go immediately for chest pain or pressure, trouble breathing, signs of stroke (face drooping, arm weakness, slurred speech), heavy bleeding, a seizure, loss of consciousness, or a severe allergic reaction.

Which countries is AI Doctor available in?

The English symptom checker works anywhere. AI Doctor also has dedicated pages for the United States, the United Kingdom, Canada, Australia, India and more, plus Arabic and French versions.
