Zettelkasten — atomic notes
TL;DR — Write notes that capture a single idea each, link them densely to related notes. Your vault becomes a self-organizing knowledge graph instead of a folder of essays.
What makes a Zettel
Section titled “What makes a Zettel”A Zettelkasten note (German for “slip box”):
- Captures one idea. Not a topic — an idea. Not “Productivity” — “Why mornings are best for hard work.”
- Is written in your own words. Quoting sources is fine; but the synthesis is yours.
- Links to related Zettels. Liberally. Every concept that connects.
- Has a stable, unique title. Future-you can find it.
- Stands alone. Re-read it 3 years from now and it should still make sense.
Why bother
Section titled “Why bother”The point isn’t taking notes. The point is the connections between notes, which only become visible when notes are atomic. A 2000-word essay-style note hides 5–10 ideas inside it. Each of those ideas could link to different things. Atomic notes surface those links.
After a year of consistent Zettel writing, the graph view becomes useful for thinking — not just pretty art.
How it pairs with Claude Code
Section titled “How it pairs with Claude Code”Several skills become more powerful with atomic notes:
- Research Synthesizer — works better when source notes are already atomic
- Spaced Repetition — atomic notes make 1–2 perfect flashcards; essays make 20 mediocre ones
- Orphan detection — atomic + densely linked means orphans really are orphans. The MOC Maintainer can flag them honestly.
Claude can also help atomize: paste an essay, ask “split this into atomic Zettels” — get back 5–10 candidate notes with suggested links.
Where to put them
Section titled “Where to put them”Either:
- Dedicated folder:
40-Resources/zettels/— clean separation - Mixed in
40-Resources/with a#zetteltag — looser
Start with dedicated. Move to mixed once you have ~100 notes and start craving cross-pollination with the rest of your vault.
