Tools for thought
The umbrella term for software meant to augment thinking through networked, atomic, interlinked notes rather than filed documents. Created during a lint pass: the phrase recurred across many pages without a hub of its own.
The lineage (this wiki’s cluster A)
- Intellectual roots: vannevar-bush‘s memex (associative-trails), douglas-engelbart‘s augmentation/NLS hypertext, and niklas-luhmann‘s zettelkasten — three independent arrivals at connection over hierarchy.
- Digital tools: tiddlywiki5 (~2004, self-contained file) → roam-research (2019, bidirectional links + graph) → obsidian / logseq (local-first plain markdown) → notion (cloud/structured-DB counterpoint) → tana (typed supertags + AI-native).
- LLM era: llm-wiki, gbrain, llm-wiki-agent — the LLM doing the linking, synthesis, and maintenance.
Shared traits & the through-line
Atomic units, liberal linking, emergent (not hierarchical) structure, a personal
knowledge-graph, and — increasingly — typed notes (Tana supertags, GBrain schema
packs, this wiki’s schema.org @type) and AI over your own structure. The arc ends
where this wiki’s thesis lives: the tools-for-thought movement and the
LLM-as-knowledge-partner idea are the same story (see synthesis).
