## What is Koe Nikki?

"Koe Nikki" is a simple voice diary app that lets you record your daily thoughts just by speaking.

Simply speak about your day, and your words are automatically converted to text. AI then summarizes your entry into a short, meaningful title. No typing required—record your diary anytime, anywhere, whether you're commuting or winding down before bed.

Completely Offline & Local:No internet connection required—ever. Works perfectly on airplanes, subways, remote areas, or anywhere without network access. Speech recognition and AI title generation all happen directly on your device. Zero data is sent to external servers.

Key Features:

• One-tap recording—just speak to create a diary entry
• Real-time speech recognition converts your voice to text instantly
• AI-generated titles summarize your day (Apple Intelligence on iOS 26+)
• Fully offline—works without any network connection
• All data stays exclusively on your device
• Clean, intuitive design
• No account needed—start using it immediately

Privacy First:No account required. All recordings and transcriptions are stored locally on your device and never sent to external servers. No cloud uploads. Your diary exists only on your device.

Perfect for those who want to start a journaling habit, prefer speaking over typing, want to capture thoughts on the go, or prioritize privacy.
