Kokoro Nikki: AI Diary

For days you want to write, and days you don't. Voice journaling, emotion insights, and a quiet visual map of your inner life — at your own pace.

Kokoro Nikki is a contemplative AI diary that listens. Speak or write what's on your mind, and watch your words become something more — a visual map of your emotions, a kintsugi timeline that honors every crack and every repair, an interior landscape that grows with you. A quiet space for intentional reflection — with a Japanese soul, designed for modern minds.

WHY KOKORO NIKKI

Whether you're new to journaling or have kept a diary for years, Kokoro Nikki gives you a gentle, judgment-free space to capture what matters. No streaks. No guilt. No performance. Just a quiet ritual that meets you where you are, on the days you have time and the days you don't.

FEATURES

• Voice journaling — speak freely, transcribed privately on your device • AI emotion analysis — notice the feelings behind your words • Interior Landscape — a watercolor that emerges from what you write • Kintsugi timeline — your story honored, cracks and all • Emotional patterns — gentle insights into the threads of your inner life • Daily reflection prompts — questions to sit with, not tasks to complete • Haiku mode — capture a day in a 5-7-5 rhythm • Seasonal themes — the app moves with sakura, summer, autumn leaves, and winter • Offline-first — your entries stay on your device • Privacy-focused — your journal is yours alone, never used to train AI

A QUIET RITUAL, EVERY DAY

Most journals ask you to perform. Kokoro Nikki invites you to listen. Speak or write freely, then let your words become a visual landscape, a kintsugi line, a quiet reflection that grows with you. The entry is the seed — what comes after is the garden.

A COMPANION TO YOUR PRACTICE

Already keep a paper journal? Use Day One? Kokoro Nikki doesn't replace what you love — it adds the contemplative AI layer that turns writing into seeing. Speak, write, then watch the shape of your inner life emerge.

PRIVACY FIRST

Your thoughts stay yours. Entries are stored locally on your device. Voice transcription runs on-device — your voice never leaves your phone. AI emotion analysis happens through secure channels, and your journal is never shared, sold, or used to train AI models. Transparent from day one.
