Chaeumil is a diary app where users record their daily emotions and experiences. Users can write about their daily routines and emotions using text, photos, and emoticons. Empathizers leave relatable comments on their diaries. Unlike social media, it's a closed platform, making it useful for those weary of social media to record their emotions and thoughts. Despite its closed nature, users can still receive comfort and support from AI empathizers. You can search and browse diaries using specific keywords or emotional tags. You can also view daily emotional changes in a graph and review past diaries in a calendar format.
