DiaryQ: AI Journal & Diary

Just text your day like you're messaging a friend. Tap "Make Diary" at night, and AI turns your notes into a real diary entry. - CHAT-STYLE JOURNALING THAT STICKS Send quick one-liners whenever you have a moment. An AI assistant chats back, so it feels like a conversation, not a chore. You're always chatting with an AI that runs on your iPhone — never another person. - AI WRITES IT UP Your scattered notes become a natural, readable diary entry. Edit it right there if you like. - CALENDAR LOOKBACK Tap any date to read and edit that day's entry. Missed a day? Generate it later from that day's chat. - PRIVATE In the free version, your chats, your diaries, and even the AI itself stay on your iPhone. No account needed. - TALK WITH WORLD TEACHERS (DIARYQ PLUS) The Buddha, Laozi, Socrates, Rumi, and Hildegard. An AI speaks in the spirit of their teachings and responds to your day from each one's perspective. The words are not theirs, and the portraits are AI-imagined. - UP TO 5 COMPANIONS OF YOUR OWN (DIARYQ PLUS) Choose a name, gender, age, personality (20 types), and job (58 types, including actor, idol, and doctor). Make a photo with AI or use your own image, then switch who you talk to right from the chat screen. Every companion is a fictional character played by AI. - PASSCODE LOCK AND ICLOUD SYNC Protect your chats and diary with a passcode (DiaryQ Plus). Turn on iCloud sync to share your records across your own devices. - DIARYQ PLUS (SUBSCRIPTION) A powerful cloud AI (Google Gemini) replies with the whole day's conversation and your character notes in mind, and writes diary entries and weekly reviews you'll want to reread. Only when Plus is on, your chat is sent to Google through the developer's relay server (not stored, not used for AI training). Switch back to on-device AI anytime from the Home screen. Chats and diaries are written by Apple Intelligence (the model built into your device), so there is nothing extra to download. On iPhones without Apple Intelligence (iOS 26 or later), you can add an optional on-device diary AI (about 340 MB). Without AI, chat logging, manual writing, and calendar review all still work. Switch the display language in the app (English / 日本語 / 繁體中文).
