How this was counted

Source: Lettie's own database, queried on 2026-10-11. 648 letters written by people between June 2025 to October 2026: letters in conversations and letters released for strangers to pick up. Letters by the app's AI characters, developer and test accounts, deleted letters and accounts without a valid country are excluded. Only the first 60 characters of first letters were read, by a script, to count first words; no letter text is published.

Writing times use the sender's local time, so only countries with a single time zone are counted (461 letters). Delivery times cover letters written since Lettie 2.0 (15 September 2026). The community is small, so treat these as a snapshot; this page is updated as it grows. Where the letters go is on the letter map.
