The goal of this clinical trial is to learn if a messaging and chatbot program, called ChatACP, helps family members of people living in nursing homes take part in advance care planning. The main questions this study aims to answer are: * Does ChatACP help family members feel more ready to talk about future medical and personal care with their loved one? * Does ChatACP help family members take part in advance care planning activities, such as having care discussions or completing planning documents? * Is ChatACP easy to use and acceptable for family members? Researchers will compare ChatACP to standard self-learning materials about advance care planning to see which approach works better. Participants will: * Receive short daily messages with pictures or videos about advance care planning and access to a chatbot specialized in ACP for 10 days * Complete surveys at the start of the study, after the program ends, and again 3 months later * Take part in an interview to share their experience with the program
