How does the symptom checker work?
You answer structured questions about your symptoms. Within minutes you get an assessment and a concrete recommendation – for example a home remedy, a medication, or a doctor's appointment.
Why a certified medical device – not Google or AI
The Well symptom checker is a certified medical device that follows medically validated algorithms. Unlike a Google search or a general chatbot, its assessment is based on validated clinical data.
What makes a medical symptom checker different?
It asks targeted follow-up questions, takes pre-existing conditions and risk factors into account, and gives a traceable, validated recommendation instead of a generic list of possible causes.
Why LLMs can't make a diagnosis
Language models generate plausible-sounding answers but aren't clinically validated or regulated. A safe assessment requires a validated and regulated medical device like the Well symptom checker.
After the symptom check – Well guides you to the right place
The symptom checker is open to everyone and shows you the next step based on the result: pharmacy, telemedicine, GP or specialist – including direct appointment booking. If you're insured with CSS or Visana, or have the KPT.win.smart model, and have entered your basic insurance model, Well factors it in automatically; KPT.win.smart members use the symptom checker as their first point of contact.
Everything ends up in your dossier
Every assessment is automatically saved to your personal health dossier – so your history is always at hand, including for your next consultation.
