Some moments are hard to write down, but easy to say.
Murmur is a private AI voice diary that captures your day in your own voice.
Speak your thoughts, feelings, and stories — and an AI companion quietly listens and writes back.
■ Just Speak, It Becomes a Diary
Tap a date on the calendar or press the + button to start recording.
Pick one of five emotions and tell the story of your day.
You can customize the emotions to fit you.
■ An AI Companion That Writes Back
When you save an entry, AI listens to your voice, reads the emotion in it, and leaves you a warm reply.
Comfort on hard days, shared joy on good ones.
■ Voice to Text, Feelings to Insights
Your words are transcribed automatically, with a summary, keywords, and emotion analysis.
The monthly report shows how your mood flowed through the month.
■ Question of the Day
On days you don't know what to say, a fresh daily question opens the conversation.
It can even remember yesterday's story and ask what happened next.
■ Warmth Streak
The more consistently you record, the more warmth you build.
Murmur helps your daily reflection become a habit.
■ Widgets on Your Home Screen
