Second Brain

A personal knowledge management approach for externalizing ideas

The "second brain" is a personal knowledge management approach focused on capturing, organizing, and retrieving notes outside the mind. In practice it often emphasizes workflows and curation: inboxes, categories, tagging, and periodic review.

It overlaps with a digital garden and a digital brain, but "second brain" tends to name the practice, while the others name the artifact and its public/private form.
