How did I build a second brain with AI

I felt overwhelmed because I had too many ideas, too many projects, and no clear system to manage everything. So I decided to build a second brain with AI. In this video, I show my real process of using ChatGPT, Claude, NotebookLM, and Notion to design a personal life operating system from scratch. This is not a polished tutorial or a perfect productivity setup. It is a real build-in-public experiment where I try to organize my life, projects, content, and personal brand into one connected system. The goal is simple: Can AI help us manage our life better, reduce overwhelm, organize ideas, track projects, and turn scattered thoughts into a working system? I start with the problem: burnout, too many tasks, too many tools, and no central dashboard. Then I use AI to research life management systems, generate a Notion structure, create a personal operating system, and think through how ChatGPT and Claude can work as second brain assistants. This video is especially for solopreneurs, creators, builders, professionals, and anyone trying to manage their life, content, projects, and personal growth with AI.
