About this app

* A diary that flows smoothly from your hands

Mira stays with you as you write, helping you look back into your heart and gently revisit your thoughts once more.
With Mira, your diary becomes richer, and you can look into the thoughts and feelings you might have let pass by.


* Even if you write just a little, it feels like a diary that reads your heart

Would you like to jot down what happened today, just like a short memo?
Then Mira will help with the rest.
Even with just a few lines, Mira can turn it into an emotional diary that feels as if it has read your heart.
On days when writing a long entry feels tiring or burdensome, just leave it to Mira.


* If you could talk without making your diary public?

Mira reads your diary, sometimes tidies up your words, and leaves comments like a friend (or in whatever role you choose).
As you reply to Mira’s comments, your thoughts and feelings grow richer, and your diary deepens.


* If you’re worried someone might read your diary

Mira does not store your diary on internet servers; it is kept safely only inside your smartphone.
So no one else can see your diary.
To prepare for the day you change phones, backup and restore are supported.
Of course, even backup and restore run only when you choose to use them.
If you are looking for a safe, secret diary, would you like to try it with Mira?


* When you want to summarize the “heart” inside your diary

Mira analyzes your entries and turns the day’s mood and emotions into emotion tags.
You can add or edit these tags yourself at any time.


* If there were a report that analyzed your diaries…

Mira provides weekly and monthly reports based on your diaries.
You can briefly look over how your emotions have been flowing.
Mira goes beyond a simple diary app and becomes an emotional self-care journal for you.


* When you want to talk with an avatar you choose, not just the default one

You can change Mira’s avatar to any photo or image you like.
You can also change Mira’s name to any nickname you prefer.
The character you set will talk with you and leave comments on your diary.


* Time to look within, together with Mira

With Mira, take a slow, gentle look at who you are today.
Instead of letting the day simply slip away,
take time to look within through your diary and your conversations with Mira.
As you write quietly and read slowly,
and exchange messages with Mira,
you may feel your thoughts settling and your heart becoming a little lighter.
