Second brain

Definition

A second brain is a personal system for capturing, organizing, and retrieving information so you can rely on it instead of memory.

——In depth

A second brain is an external, organized store of your notes, ideas, references, and tasks. The idea is to offload memory to a trusted system so your mind is free to think rather than to remember.

Tools like Notion are popular second-brain platforms because they combine notes with databases and links. The value is not in capturing everything but in being able to find and reuse it later.
