Swapnote, known as Nintendo Letter Box in PAL regions and Suddenly Exchange Diary in Japan, is a messaging application for the Nintendo 3DS family.

In November 2016, Nintendo released a successor called Swapdoodle.
On March 27, 2023, Swapnote and Swapdoodle were made unavailable to download due to the closure of Nintendo eShop services for the Nintendo 3DS.
Swapnote allows users to send hand-written/drawn messages to either registered friends online via SpotPass or other users locally via StreetPass. The app also allows users to freely embed pictures and sounds into their messages, and change the position and the orientation of the picture and sound icons. Features are unlocked as players continue to send letters, such as the ability to hand-write/draw 3D messages, with additional stationery and features unlocked by spending Play Coins. Additional stationery can be obtained via certain Nintendo related events, such as using specific software, or by saving them from other people's messages.
