**Slow Letters** is a correspondence app for people who want depth over speed.
Every correspondent is built with a full life dossier from birth onward: childhood, habits, relationships, turning points, and emotional rhythm. When you write, your letter enters this living context, and the reply reflects that character's history and current mood.
What you can do:
- Move between the `Relations`, `Discover`, and `Account` tabs
- Browse correspondents with profile archives and timeline context
- Write the first letter, save the relationship draft, and wait for the exchange to unfold
- Review recovery, language, sign-out, and account deletion controls in `Account`
Slow Letters is not chat. It is a slower, intentional form of communication.
