Summary

This study tests whether a friendly chatbot app can help high-risk drinkers reduce their alcohol intake. About 220 adults who want to drink less will use the app for four weeks, and researchers will check their drinking habits at 4 and 16 weeks. The goal is to see if the app's motivational conversations lead to real, lasting changes in drinking behavior.
