Google OKF catalog
Your Second Brain stays structured, portable, and yours.
DeanOS stores what it learns in Google's Open Knowledge Format, a readable catalog for facts, concepts, sources, and relationships. Plain English version: your second brain is organised like a library, not buried inside a chat log.
