About Mimu - AI Alter Ego Diary
[What is Mimu?] An AI alter ego that writes your diary for you, every single day. You want to journal but can't keep it up. You're too busy to reflect. Mimu solves this -- your alter ego stays by your side all day, observing and recording your life. This is not a chatbot. It's a new kind of journaling where "your other self" writes for you. [A Day with Mimu] - Morning Greeting Your alter ego greets you each morning with words just for you. Share how you're feeling today. - Whispers & Inner Voice Throughout the day, whisper your thoughts. Your alter ego responds with an "inner voice" -- not a chat, but an internal dialogue, like talking to yourself. A small mindfulness pause in a busy day. - Nightly Diary At the end of each day, your alter ego writes a diary reflecting on your mood, whispers, weather, and more -- weaving it all into one story. [Grows with You] Your alter ego builds memory over time, and that growth shows. Day 1 entries are simple. Month 1 entries show real insight and become a space for self-reflection. It notices patterns you never saw: "You tend to feel low on Mondays." "Days when you whisper more are actually your happier days." [Uniquely Yours] Customize the name, personality, and tone. MBTI, zodiac, and personality traits shape how your alter ego thinks and writes. No two are alike. [Features] - Every word is AI-generated daily -- no templates, ever - Mood tracker calendar to visualize emotional patterns and support your mental health - Diary archive for easy reflection -- a few zen minutes of self-care each day - iCloud sync across devices - Available in Japanese, English, Korean, and Chinese [Subscription] - Monthly: $2.99/month - Yearly: $29.99/year (save 17%) - Both include a 3-day free trial - Auto-renews after trial unless cancelled - Cancel anytime in Settings > Apple ID > Subscriptions [Privacy] No personally identifiable information is sent to the cloud. Your diary data is stored securely on your device and in iCloud. Terms of Use: https://mimu.remosia.biz/en/terms Privacy Policy: https://mimu.remosia.biz/en/privacy
What’s new
Version 1.0.4 · Updated September 8, 2026
Reworked how the Hitorigoto screen is laid out. Improved: - While a weekly Reflection or monthly Footprints notice was waiting, the screen used to give it priority. It now sits alongside the day's own whispers and replies, and the remaining count always reflects where your day actually stands. - Notice cards show the period they cover, so you know which Reflection or Footprints you are about to open. - The middle layer of the morning greeting — yesterday's recap — now has a heading, so each of the three messages is easy to place. - In the journal list, Reflection and Footprints cards are headed by their period.
