Daybook brings your work tasks, personal to-dos, notes, calendar, and daily activity together in one place. Organize tasks for work and personal life side by side, with due dates, priorities, and reminders. Keep freeform notes and hand-drawn sketch notes for quick ideas. See your day at a glance with a built-in calendar that includes holidays and birthdays. Log your daily activity automatically, with optional location-based auto-start when you arrive at a saved place. Ask the built-in AI assistant to summarize, organize, or draft from your notes and images, using your own Gemini API key. Back up and sync your data to your own Google Drive, and optionally sync events with your device calendar. Your data stays local on your device by default. Google Drive sync and the AI assistant are both optional and fully under your control.
