DiaryQ

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.

• COMPLETELY PRIVATE Your chats, your diaries, and even the AI itself stay on your iPhone. Nothing is ever sent to a server. No account needed.

The AI runs on your iPhone (optional one-time download of about 3.6 GB for the high-quality model; works offline afterwards — the app works fine without it, too). A recent device (iPhone 15 Pro or later) is recommended for the on-device AI. Without it, chat logging, manual writing, and calendar review all still work.
