Voice journal with AI mood tracking. Speak or write your diary. No streaks.

Kokoro Nikki is a voice journal that listens. Speak or write, and your day becomes an entry, a reading of how you felt, and a watercolor painted from your own words. No streaks. No guilt. Nothing to keep alive. OPEN IT AND WRITE No sign-up, no password, no form. We do not ask for your email. WHY THIS DIARY IS DIFFERENT Most journaling apps turn writing into a scoreboard. Miss a day and the app tells you so. Kokoro Nikki has no counter to protect. Open it, talk for a minute, and the diary writes itself. Come back in three weeks and it greets you the same way. It is a diary for people who like the idea of journaling more than the discipline of it. WHAT YOU CAN DO • Voice journaling: speak, and your voice becomes a written entry • AI emotion analysis: 13 emotions read from what you actually wrote, not picked off a list • Mood tracker: watch how your mood moves across weeks and months • Interior Landscape: a watercolor that grows out of your own entries • Kintsugi timeline: your whole story, cracks and repairs included • Daily reflection prompts: questions to sit with, not tasks to complete • Haiku mode: a day in 5-7-5 • Seasonal themes: the app moves with sakura, summer, autumn leaves and winter • App lock with your phone's fingerprint, face unlock or screen PIN, and it asks again to turn the lock off • Write by voice in up to 25 languages, whatever language the buttons are in • Your entries are stored on your device A VOICE DIARY FOR THE DAYS YOU CANNOT WRITE Some days you do not have the patience to type. Say it out loud instead. Voice journaling turns a spoken minute into a written entry you can read back later, which makes this a practical daily journal for the commute, the walk home, or the ten minutes before sleep. Closer to a voice notebook than a voice recorder: the recording becomes text you can search, read and keep. MOOD TRACKING THAT READS INSTEAD OF SCORING A mood tracker usually asks you to rate the day from one to five. This one reads the entry. AI emotion analysis names what sits under the words, and those emotional patterns build up over time into something you can actually look at: a mood diary, a gratitude journal, a record of stress, anxiety, calm and everything in between, without you having to label a single thing. A QUIET RITUAL Most journals ask you to perform. Kokoro Nikki asks you to notice. Speak or write, then let your words become a landscape, a line of gold, a reading of how you have been. The entry is the seed; what comes after is the garden. It works as a daily journal, a self care habit, a mindfulness practice, a mental health check-in, a gratitude journal, or plain old diary keeping. BUILT FOR THE LONG RUN Kokoro Nikki borrows kintsugi, the Japanese craft of repairing broken pottery with gold. Nothing in your timeline gets hidden because it was a bad week. The breaks stay visible, and they are part of what makes the record worth keeping. YOUR PRIVACY, WITHOUT THE FINE PRINT We would rather be exact than sound good: • Your entries are stored on your device. • The audio of your recordings is never uploaded to any server of ours. • To turn your voice into text, Android hands the recording to its own speech recognition service, so that step happens off the device. • Emotion analysis is optional. It sends the text of the entry, never the audio, to a secure service that returns the result. You can decline it and keep writing. • Your journal is never sold and never used to train AI models. FREE TRIAL AND SUBSCRIPTION 7 days with everything included. After that a subscription is needed to write new entries, but your diary does not go anywhere: you can still read everything you wrote and export it whenever you want, as a Markdown file that carries your data in JSON. The amount and the renewal date are shown in full before you pay, with no extra tap. No surprise charges.
