Core Capabilities
Built From the Ground Up for Voice
Typing is slow and censors your spontaneous emotions. Voice journaling unlocks authentic self-reflection and mental clarity.
Frictionless Voice Journal & Audio Diary
One tap to record. Whether taking a walk, driving, or winding down before bed, capture unfiltered stream-of-consciousness audio diary entries without typing fatigue.
AI Voice-to-Text & Summaries
Integrated with Google Gemini language models to convert spoken voice reflections into crisp bullet points, emotional mood insights, and immediate to-do items.
Interactive Knowledge Graph
VoiceDiary correlates repeated names, goals, habits, and places across your entries, forming an interactive network of your memories.
Uncompromising Privacy
Your reflections are sacred. Client-side encryption ensures only you have the keys to your recordings and transcripts. No public AI model training.
Seamless Cloud Sync
Powered by Google Firebase infrastructure. Automatic cloud backup for audio files and text entries ensures your journal is never lost.
Background Studio Audio
Play back previous reflections with custom playback speeds, lock-screen controls, and rich synchronized visualizers.

Frequently Asked Questions
Everything you need to know about VoiceDiary, AI transcription, and privacy.
People speak on average 150 words per minute, but type only 40 words per minute on phones. Speaking allows unfiltered, emotionally raw thoughts to flow without writer's block or self-editing. VoiceDiary gives you the authentic preservation of your spoken voice with the convenience of organized, searchable text.
You can download VoiceDiary directly on the Google Play Store for Android. Our Apple iOS release is currently in active development and will be available on the App Store soon.
Traditional journaling apps like Day One require manual keyboard typing or treat audio recordings as plain attachment clips. VoiceDiary is architected voice-first: it automatically transcribes speech with Gemini AI, extracts emotional moods and actionable to-dos, and weaves your memories into an interactive knowledge graph—delivering effortless reflection with zero typing friction.
Yes! VoiceDiary serves as both a full-featured audio diary with background studio playback and an intelligent voice-to-text journal. You can listen back to your original spoken voice recordings or read through AI-structured transcripts, summaries, and emotional trends anytime.
Never. We use enterprise AI APIs (such as Google Gemini) configured under zero-data-retention and zero-training policies. Your spoken voice recordings and transcripts remain 100% private and are used solely to generate transcription and insights for your account.
The Knowledge Graph is a visual map showing recurring people, topics, projects, and emotions mentioned across your voice recordings. It lets you discover hidden patterns—such as how certain activities impact your mood—across weeks and months.
You can instantly delete all account records directly inside the app (Settings → Account & Cloud Sync → Delete Account), or submit a web deletion request via our Data Deletion Request Page. All Firebase records and audio files will be permanently purged.
