A Second Brain is a personal knowledge management system that helps you capture, organize, and retrieve information and ideas.

The core idea is to systematically save and organize valuable information you encounter - like articles, notes, ideas, quotes, or observations - in a digital format thatā€™s easy to search and reference later. This helps prevent valuable insights from being forgotten and enables you to make better connections between ideas over time.
