What is a Second Brain?

A second brain is a digital extension of your mind—a personal knowledge management system that captures, organizes, and connects your thoughts, ideas, and insights. It's designed to remember what you forget and help you think better.

Unlike traditional note-taking, a second brain system uses AI to automatically organize information, discover connections between ideas, and surface relevant knowledge when you need it most.

"Your mind is for having ideas, not holding them."
— David Allen, Getting Things Done
