## What is Mitsuba?

A gratitude journal that grows with you.
Record three good things from your day, add a photo, and grow a little garden. Miss a day? Your plant keeps its progress.

Keep a small good thing in words and photos.
Mitsuba is a gratitude journal with a little garden that grows as you write.

A warm cup of tea. A kind message. Light through the window.
Your companion asks about your day, one good thing at a time. You only need a few words. Recall and record three good things to complete your daily reflection. You can save your progress and come back later.

WRITE A LITTLE. GROW A LITTLE.
Your plant grows one stage on each journaling day. After seven journaling days, it is fully grown and a harvest card gathers the memories along the way. Those days do not need to be consecutive. Missing a day never resets your plant or takes away its growth.

ADD A PHOTO TO THE MOMENT
Attach one photo to each day's entry. Replace it, remove it, or open it larger whenever you like. Revisit your words and pictures in your journal and weekly reflections.

A WEEKLY LETTER FROM YOUR COMPANION
Browse Monday-to-Sunday memories with their photos. Enable optional AI letters and your chosen companion will write a letter looking back on your week, based on your journal. Ask for a rewrite whenever you want a fresh reflection. With automatic letters enabled, the app prepares last week’s letter when you open it after the week ends. Even one recorded day is worth revisiting.

TALK WITH YOUR COMPANION
Choose gentle Mitsu, warm Hina, or quiet Yoru and talk about your day or how you feel. Online AI follows the conversation to create a reply. Enjoy a roomier chat view, and review and edit your own words before adding them to today’s journal.

ENCOURAGEMENT AT YOUR PACE
Choose a writing reminder, a Monday morning reflection reminder, and celebrations for 10, 30, 100, and 365 recorded days. Change them individually in Settings. Milestones count total days, not streaks. Writing reminders stay quiet on days you have already written.

MAKE THE GARDEN YOURS
Enjoy 12 basic plants, choose your next seed, explore your collection, name your grown plants, and share plant cards. Journal memories appear in shared images only when you select them. Botanical Seeds is an optional one-time purchase that adds three rare plants to grow again and again.

JOURNAL AND PHOTOS SAVED ON YOUR DEVICE
No account registration, ads, behavioral analytics, or tracking. Journaling and basic plant growth work offline. Export as text or JSON; JSON includes attached photos and saved weekly letters.

AI conversations and letters are optional and require an internet connection and your consent. When used, your conversation and relevant journal text, or the selected week’s journal text and dates, are sent outside your device along with language and companion information to generate replies and letters. Photos and mood scores are not sent. Turn AI off in Settings at any time.
Mitsuba’s server does not store journal text or replies. Anonymous authentication identifiers and usage counts are processed to prevent misuse. See the privacy policy for details.
AI content can contain mistakes, and usage limits apply. Journaling, photos, plant growth, and browsing weekly entries remain available without AI. Seed purchases and restoration require an App Store connection. Retrieving photos stored in iCloud may require an internet connection.

Available in English, Japanese, Korean, and Traditional Chinese.
Start with something small. Keep it with Mitsuba.
