Overview

Personal Knowledge Management (PKM) is the set of practices, methods, and tools an individual uses to capture, organize, connect, and retrieve information — transforming raw information into usable knowledge.

Unlike organizational knowledge management (top-down, standardized), PKM is designed around the individual’s unique mental models, goals, and ways of thinking.

Key Approaches

  • Zettelkasten: A note-taking system developed by sociologist Niklas Luhmann emphasizing atomic notes and emergent structure through linking
  • Building a Second Brain (Tiago Forte): PARA (Projects, Areas, Resources, Archives) organization method
  • Digital gardens: Public, non-linear knowledge spaces that grow over time — like this one
  • Evergreen notes: Andy Matuschak’s concept of notes that are continuously refined rather than written once

Tools

  • Obsidian, Roam Research, Notion (note-linking tools)
  • Readwise (highlight capture and spaced repetition)
  • Anki (spaced repetition for memorization)
