WhisperMemo is a Japanese and English voice diary for capturing thoughts before they disappear. Tap, speak, and let on-device transcription and AI turn your recording into a useful journal entry with a title, emotion, topic, summary, and key points. Key features - Tap to record and transcribe entirely on device - On-device AI generates title, emotion, topic, summary, and key points (uses Apple Intelligence on supported devices; on other devices, you can optionally add a local AI model) - Weekly AI summary in 3-5 sentences - Monthly calendar view of your journaling rhythm - Emotion filter and topic filter: work, health, idea, relationships, learning, and other - iCloud sync keeps your memos consistent across your Apple devices - Optional Markdown auto-export to your Obsidian Vault - Optional audio backup to iCloud Drive - Home Screen widget with weekly stats and latest memo - Optional daily morning reminder notification WhisperMemo is built for people who want to keep a diary but do not want to type. It works well for fleeting ideas, commute reflections, post-drive notes, learning logs, and quick emotional check-ins. Short recordings become searchable, structured entries you can revisit later. Privacy is central to the app. Your audio, transcription, and AI analysis are processed on device and are not sent to WhisperMemo servers. Obsidian export and iCloud Drive backup are optional and only run when you enable them. iCloud sync stays inside Apple's iCloud service. Speak now, reflect later.
