What is a Second Brain? 

A second brain app is a digital tool designed to help you capture, organize, and store your thoughts, ideas, and information in a structured way that you can retrieve them anytime.

Building a second brain will extend your cognitive processes and ability, providing a structured and easily accessible repository for your notes, documents, and creative insights.

Tiago Forte introduced the second brain concept first in his book Building a Second Brain.” He reasons that humans can’t always remember every piece of daily information, as it can get overwhelming.

Tiago went further to list the benefits of relying on the second brain system:

  • Organizes your information perfectly, making access easy 
  • Keeps information unless you delete what you no longer need 
  • Preserves your creativity and ensures your work is tracked, allowing you to revisit it anytime
