Basic Usage
“Shijima Diary” is a simple app designed for you to express your thoughts as they are. No special settings or complex operations are required. Feel free to enter whatever is on your mind or whatever happened today.
1. Writing in Your Diary
Enter your feelings or daily events in the input field at the bottom of the screen. There is no need to try to write well or perfectly; even a few short words are perfectly fine.
2. Dialogue with AI
The AI will respond gently to what you have written. The conversation is designed to naturally draw to a close after a few exchanges, emphasizing the importance of organizing your thoughts and helping you feel ready for the next day. When the conversation ends, the AI will automatically generate a title for your diary entry based on the content. Depending on the tone of the exchange, a color theme will be gently added to your entry, allowing you to reflect on your feelings later. This color is assigned automatically and cannot be changed by the user.
3. Reflecting on Your Entries
You can look back on your diary entries at any time via the list view or calendar view. By reading your past thoughts, you can notice your own changes over time.
4. Editing and Regenerating Titles
On the diary list screen, you can long-press each entry to open the edit menu. The following options are available:
- Edit Title Manually
- Regenerate Title with AI When regenerating, the AI will summarize your day’s feelings or events into a short, natural title.
5. Letting Go
The purpose of writing is not just to “keep a record.” It is also a space for you to vent your feelings and gradually “let go” of them.
