K’s cutting-edge AI asks simple, relevant questions to help you understand your symptoms and give you immediate answers you can trust.

Tell K your symptoms to start feeling better

In order to feel better, you first need to find out what’s wrong. K asks smart questions about your symptoms and accounts for your age, gender, and medical history as it investigates your health. K is more than just a symptom checker and has been trained on millions of real, anonymized medical records, to show you how people like you were diagnosed and treated.

No more waiting rooms

We’ve redesigned the doctors’ visit and turned it into an ongoing conversation that feels like texting with a friend. You don’t need to schedule an appointment and pay a fee to get trusted answers about your health.

Personalized answers

Other symptom checkers rely on static rules or protocols to give you their best guess at a diagnosis. K was built by doctors and trained on millions of real medical records to give you more accurate results.

Your records are always private

Records of your symptoms and care stay on your phone. Plus, K Health complies with both HIPAA + GDPR, the world’s leading standards for information security and privacy. We use anonymized data to make the app smarter, but we will never share your personal health information.
