MaruLog: AI Emotion Diary

A diary you can keep even on the hard days.

MaruLog is an AI emotion diary that holds your difficult feelings instead of pushing them away. If today felt heavy, write it down, even a line. The AI reflects your story back and offers a warm word, and finds the trends and patterns in what you've written. If it senses you're in danger, it quietly points you to professional help.

■ It holds the hard feelings too
No forced gratitude or positivity. Sadness, anxiety, and burnout are welcome as they are.
The AI responds with empathy, never judgment, and offers a warm word.
Choose the AI's tone: a warm companion, a quiet presence, gentle cheer, or a close friend.
When what you write sounds really heavy, it shares a local helpline.
(MaruLog is a self-care diary, not a medical device. It does not diagnose, treat, cure, or prevent any medical condition. For medical advice, diagnosis, or treatment, please consult a healthcare professional.)
