How was your day today? 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 See this month's moods at a glance with the emotion calendar widget. ■ Your Year, Wrapped At the end of the year, Murmur gathers your voices and emotions into a personal recap. Turn favorite moments into emotion cards and share them with friends. ■ Private and Safe Protect your space with app lock (PIN and biometrics), and keep your entries safe across devices with cloud backup. ■ Murmur Premium - Recording time 10 → 20 minutes - AI emotion analysis, summary & keywords - Replies from your AI companion - Photo attachments & monthly report - Cloud backup - No ads Your voice is your most honest diary. Start telling your story today.
