How to build and use Second Brain.

Rahul Kumar
Timeln
Abstract

Most people talk about AI tools. I want to talk about the thing that makes them actually work i.e. Memory. Not the model, not the prompt, the persistent knowledge layer underneath it all. I'll walk through how high-performers are building their second brain: a structured, queryable layer of their own thinking that compounds over time. I'll cover what actually needs to go in (and what doesn't), how to design it so an LLM can reason over it, and what this looks like in practice for founders, consultants, and operators running on context-switching overload.

Bio
