Thanks to a new technology marrying telemedicine and artificial intelligence, the days of “self-diagnosis by Google” may now be over. Using a chatbot interface (which has led some to dub it the “Alexa of health”), the Ada app helps users narrow down what might be ailing them. After asking about symptoms and other health data, it matches the information with earlier cases and supplies possible explanations. U.K. customers can also pay an extra fee to be put in contact with a real doctor, who will review the assessment, discuss it by phone and even issue prescriptions. Alternatively, the app can recommend the right doctor for the patient to visit with the pre-diagnosis. The Berlin-based startup is also collaborating with top research institutions to improve the app’s diagnostic intelligence.
