MayDiary is your personal space for safe and smart journaling. It combines classic diary writing with cutting-edge artificial intelligence technologies that help you better understand your experiences, emotions, and life patterns. KEY FEATURES: AI ANALYSIS & TRENDS: Get intelligent summaries of your past week, month, or year. MayDiary analyzes your moods, identifies key moments, and uncovers trends you might otherwise miss in regular text. SMART TRANSCRIPTION: Capture your thoughts faster than you can forget them. Use Apple’s lightning-fast local transcription or the advanced OpenAI cloud engine for precise formatting of dictated text. SMART TAGS: Organize your entries with fully integrated tags throughout the app. Add tags manually or let AI suggest them. You can then filter by tags or use them for more accurate AI analysis. NATURAL SEARCH: Can’t remember when you wrote about something? Just ask. The AI filter finds entries based on their actual meaning and topics, not just exact words. PRIVACY FIRST: Your diary belongs to you alone. Data is securely stored in the app’s sandbox and protected by iOS system encryption. If you use sync, entries are saved to your private iCloud database linked to your Apple ID. You can also secure access to your diary with Face ID or Touch ID. MODERN EDITOR: Enjoy a clean and clear environment with Markdown support for perfect structure in your notes. NO ADS, NO DATA COLLECTION: MayDiary was created as an independent project with a focus on user experience. The app is free, contains no ads, and your texts are never used to train AI models. WHY MAYDIARY? Unlike ordinary diaries, MayDiary helps you find meaning in your writing. It’s a digital companion for personal growth that holds up a mirror and provides practical recommendations for your wellbeing and mental health. NOTE: To use AI features, you will need your own OpenAI key. Instructions can be found directly in the app.
