Parking spots, Wi-Fi passwords, locker numbers, today-only reminders β€” jot it down and forget about it. Dayfly cleans up after itself. Attach photos and videos too. That whiteboard, a receipt, a photo you only took to ask an AI about β€” capture it and share it straight from Dayfly. Dayfly-managed attachments are removed when an expired note is cleaned up. Photo-library originals and shared copies remain. Want to keep something?
