Better than Google and ChatGPT: discover our symptom checker created by doctors

When we have a headache that just won’t go away or feel a weird pain in our elbow, what’s the first thing we often do? Google. And what does it tell us? Usually a mix of alarming, contradictory and often stressful hypotheses (hello cancer!). If it’s not Google, it’s ChatGPT, and while this chatbot is useful for different things, a doctor it is not… and should not be used for medical advice.

When it comes to our health, always rely on a trustworthy, tried and tested tool. That’s where Bonjour-santé's symptom checker for self-diagnosis makes all the difference.

A reliable medical tool, created and backed by doctors

Unlike popular web search engines, the Bonjour-santé symptom checker has been designed and validated by a team of doctors who have spent more than 120,000 hours analysing various symptoms and their most likely causes. Each recommendation and scenario is based on sound clinical protocols backed up by proven medical technology.

Available 24/7, the self-diagnosis symptom checker doesn't just collect information: it analyses your symptoms to identify the most likely causes among more than 1,000 common pathologies, and directs you to the appropriate care. Depending on the severity of your condition, the tool can recommend treating yourself at home, seeing a doctor or another healthcare professional, or even contacting emergency services.

That said, the Bonjour-santé symptom checker is not intended to replace the advice of a doctor; it will help you better understand your state of health and direct you to the right care, at the right time.

The power of AI for your health

Bonjour-santé's symptom checker is not only reliable; it also learns and improves over time as it analyses symptoms, thanks to artificial intelligence. With each use, it becomes more powerful, more accurate and more personalised. 

Whether you're describing symptoms of bronchitis, sciatic nerve pain, dizziness or a sore throat, our AI works rigorously to provide you with a clear, rapid and tailored response.

A simple, quick and reassuring experience 
  1. Enter your information or that of someone else (child or adult).
  2. Describe symptoms and answer a few questions.
  3. Get a personalised analysis of the probable causes in just a few minutes.
  4. Receive concrete recommendations in terms of care.


Why is it better than Google and ChatGPT?
  • Created by doctors, not by generic algorithms that comb through various - and often unverified - sources.
  • Clinical validation of causes according to their level of probability, and related recommendations.
  • Continuous AI optimisation, with millions of cases analysed.
  • Secure, confidential and respectful of your data.
  • Useful and accurate answers, with no worrying assumptions or unreliable foundations.
