Knowledge Bases
This hub is for tools and methods that treat notes as working memory rather than as a single final document. The useful distinction is not just "editor" versus "not editor." It is whether the system supports retrieval, cross-reference, staged drafting, and long-lived accumulation in a way that changes how you think and write.
Obsidian is one current product example because it keeps local files, links, metadata, and plugins in view. But the category is broader than one company: wiki-like systems, linked-note software, research archives, and other local-first authoring tools belong here too.
What this page should help answer
Use this route when the question is practical: what makes a tool a knowledge base, which kinds of structure matter, and where the category overlaps with writing, research, and publication. The point is not generic productivity advice. It is to understand which properties actually change author workflow.
- Which features move a tool from plain editing into knowledge-base behavior.
- How local files, links, tags, metadata, and search affect long-lived writing projects.
- How private note systems later feed essays, books, documentation, or worldbuilding surfaces.

Useful when the question becomes "what exactly is the Markdown substrate?" rather than "what does this app add on top?"
Markdown
The original Markdown project page is still a helpful anchor for the older, lighter-weight file-format side of the ecosystem.
