Obsidian
Build a personal knowledge base from linked notes.
What is Obsidian?
Obsidian is a note-taking environment built around local Markdown files and connections between ideas. It provides a way to organize research, journals, and project knowledge while retaining a readable file format outside the app. Optional services support syncing and publishing. It suits people who prefer shaping their own knowledge system, with the tradeoff of maintaining its structure and extensions themselves.
