What is Second Brain?
Building a Second Brain is a digital knowledge management system by Tiago Forte. It creates an external "second brain" organized with the PARA method (Projects, Areas, Resources, Archives). The key is not just storing information, but accumulating it in a form ready for future use.
Building a Second Brain is a digital knowledge management methodology systematized by Tiago Forte in his 2022 book. It selects "future-useful" information from everything you encounter daily (articles, videos, conversations, ideas) and organizes it into four PARA categories. The CODE workflow (Capture, Organize, Distill, Express) transforms inputs into outputs, maximizing intellectual productivity.
The Four PARA Categories
Email Memo as Second Brain Gateway
Simple Memo handles the "Capture" phase of the Second Brain CODE workflow. Ideas, quotes, and inspirations encountered daily are captured the moment they land — the cursor is live 0.4 seconds after the tap — and sent to your email with one tap. During email processing, sort them into your PARA system in Notion or Obsidian. By eliminating capture friction, you increase both the quantity and quality of information entering your Second Brain.
