About this app

Just one word a day is enough. Simply write, and the AI ​​will respond. The reason you might struggle to keep a diary might be because you have too much to write about. Kiroku is a diary app that only requires one line. Just write a single word about what happened or how you felt today. Then the AI ​​will read your words and provide a comment. ■ AI provides a one-line comment Once you finish writing, the AI ​​will add a short comment to your diary. It could be encouragement, empathy, or an insight. Just having a response to something you couldn't tell anyone else can lighten the burden a little. ■ Mood score from 0 to 100: Quantifying your mood today The AI ​​determines your mood score from your diary entry each day. It turns that vague feeling of "feeling down" into a visible number. ■ Emotion graph reveals your emotional fluctuations Your daily score is displayed as a graph, and the calendar is colored with your mood. The more you continue—a week, a month—the more you'll see your own mood patterns. ■ Google Calendar Integration (Optional) When you load your schedule, the AI ​​will comment based on what happened that day. "You've had a busy few days, haven't you?"—that's the kind of response you might get. ■ For those who: ・Start a diary but only keep it for three days ・Want to understand their mood swings ・Have things they want to vent about but don't feel the need to talk to someone about ・Want to be able to look back on the day's events later ━━━━━━━━━━━━━━ Premium (¥480/month / ¥3,800/year) ━━━━━━━━━━━━━━ ・100 credits awarded monthly ・Contextual AI comments (responses based on the past 7 days of diary entries) ・Customize AI responses to your liking ・Mood analysis report (weekly/monthly graphs) ・Monthly AI report ・View past data for the entire period ・No ads ・Export diary entries (PDF/image) ・20% off credit purchases Credits can also be purchased individually (10 / 50 / 150 / 500).
