Description by Hiromasa Nakatani Written by the developer, not by AppBrain. Click to read.
Every entry receives a reply from AI, making journaling feel like a conversation.
You don't need to write long diary entries.
Even a short sentence is enough.
• Simple “tweet-style” journaling
• AI replies to your thoughts
• Record feelings, moments, and daily life
• Look back through your timeline anytime
Examples:
"I woke up early today."
"I finally tried the pasta place I wanted to go to."
"I found a really cute flower on my way home."
Small moments deserve to be remembered.
Not a social network.
Just a quiet space for you.
