Just speak. See yourself clearly. Voice journaling with AI — emotion map, weekly reflection, thought-clearing. Long-term patterns on Pro. Privacy first.
Just speak. See yourself clearly.
kotonoha turns your voice into a private reflection practice. Talk freely — AI organizes the rest.
■ Why voice
Writing loses momentum. Typing filters your real feelings. Voice is the fastest, most natural interface to your inner world. You notice things while speaking, and fuzzy feelings start taking shape.
■ Two taps, one entry
1. Tap the mic
2. Speak freely — anything
When you stop, AI summarizes your words, scores the emotion, and extracts key themes in seconds. No writing pressure. The day you just lived is recorded.
■ What you get
• Voice → text transcription (on-device, your audio never leaves your phone)
• AI summary, emotion score, and key themes
• Emotion map — past entries connect like a galaxy
• Emotion radar — 5-axis visualization (calm, joy, anxiety, anger, sadness)
• Weekly review — your week in three numbers
• 12 themed prompts — when you don't know where to start, pick one after a breath
■ Pro: deeper insight
• Long-term pattern tracking — rising emotions, surfacing themes, time-of-day patterns
• Notes from kotonoha — gentle insights and questions
• Advanced AI analysis (top-tier Claude model)
■ Privacy first
Your voice becomes text on your device. Audio is never uploaded. Only text and analysis results are stored, encrypted. Delete everything at any time.
■ Best for people who
• Quit journaling after three days

■ Fixes
The post-recording analysis screen no longer gets clipped at the edges on some iPhones. Emotion radar, summary, tags, and kotonoha notes now fit beautifully on every screen.
More room to listen to your own voice.
