Description by Yunsu Park Written by the developer, not by AppBrain. Click to read.
Bottle Diary is an interactive journaling app where you record your day by chatting with an AI cat.

Tell your cat what happened today.
As you enjoy a relaxing conversation, the cat will turn your story into a thoughtfully written journal entry.

You can talk about happy moments, difficult experiences, or even the smallest parts of an ordinary day. There’s no need to worry about what to write—simply follow the conversation, and your journal entry will come together naturally.

You can keep your completed entries private or share them anonymously. Read journals shared by others, leave kind replies, and experience a quiet sense of connection—even without knowing each other’s names.

Earn coins by writing entries and reading other people’s stories. Use your coins to dress up and care for your own cat, making journaling a cuter and more enjoyable daily habit.

It’s okay if you don’t know what to write.
