Karpathy Obsidian second brain graph

yazan Vojtech: Andrej Karpathy

Millions of bits hit your brain every second and almost none of it sticks. A second brain is the living network that catches the rest, every idea, every note, every connection one person has made, mapped out as a searchable web. Thousands of nodes, hundreds of live links between thoughts, years of thinking compressed into a system you can query. Karpathy’s approach turns Obsidian into an OS for your own mind, and the complete A, Z guide for building it with Claude and Obsidian is written.
