>[!abstract] >An exobrain is a metaphor for external systems—such as digital tools, notes, or collaborative platforms—that extend and augment human memory, cognition, and creativity. By offloading storage, retrieval, and pattern-recognition tasks onto technology, an exobrain functions as a cognitive scaffold, enabling individuals to think more clearly and handle greater complexity than they could unaided. Examples include personal knowledge management systems, [[Digital garden|digital gardens]] like this one, [[Zettelkasten]] vaults, and shared digital workspaces. The concept highlights the increasingly porous boundary between human thought and externalized information structures, framing cognition as distributed rather than confined to the biological brain. >[!related] >- **North** (upstream): [[DIKW pyramid]] >- **West** (similar): — >- **East** (different): — >- **South** (downstream): [[Digital garden]], [[Zettelkasten]]
