FeverCoach - US

The Best Child Healthcare Solution At Home

FeverCoach, a digital guide for parents to manage their child's fever and health concerns right from their smartphone.

FeverCoach brings to American families the approach behind 열나요 (Yeolnayo), the fever app our team co-created in Korea and one of the most widely used pediatric apps there. Renowned for its user engagement and reliability, that work reshaped how Korean parents manage a child's fever at home. FeverCoach adapts it for the United States: the same careful record-keeping and practical next steps, built for US parents and in active development by MoDoc AI.

People already bring their health questions to AI assistants. Most treat them like an upgraded search box; a few trust them far enough to skip the emergency room. This book is written for the space in between — how to get real use out of an AI assistant without handing it a decision it cannot make.

It is written by practising physicians, and it is not a prompt collection. Each chapter follows one realistic conversation from the first vague question through the follow-ups, then stops to check what the AI got thin or wrong.

  • Understand the tool

    What today's AI assistants actually do with a health question — and where they quietly go wrong.

  • Work through real problems

    Symptoms, appointments, test results, medications, chronic conditions, insurance, family and mental health — each with a worked conversation, not a prompt to copy.

  • Know when to stop

    Every chapter opens with its red flags: the moment to close the app and call a clinician instead.

The book is for information only. It is not medical advice and does not replace a consultation with a qualified clinician.
