## What is Kototsumugi?

Kototsumugi is a conversational AI diary app.

You do not need to write perfectly.
Share what happened today, what stayed on your mind, or feelings that are hard to put into words. Kototsumugi turns the conversation into a diary that feels like you.

For people who want to:

- Build a diary habit
- Use an AI diary app
- Create a journal through conversation
- Reflect on each day
- Organize feelings and thoughts
- Practice self-care
- Keep memories in writing
- Turn small fragments into a daily record

What you can do with Kototsumugi:

- Create diary entries from AI conversations
Talk naturally, then turn the conversation into a diary.

- Save fragments of feelings
Keep words, moments, and emotions as small fragments you can revisit later.

- Write in a style that fits the day
Create gentle, natural diary entries based on your mood.

- Look back through history
Read past entries and notice changes in your feelings and everyday life.

- PRO plan
Create more diary entries, save more fragments, and use the app without ads.

Kototsumugi quietly supports your daily reflection.

Small moments and unnamed feelings can become meaningful records when you look back. Talk with AI and keep the movement of your heart, one day at a time.
