Obsidian is a note-taking application that builds a personal knowledge base from Markdown files in a local folder. It is characterized by connecting notes with double-bracket links and visualizing those relationships in a graph view, and it differs from cloud-based tools such as Notion in that the data stays in the user's own files rather than on the service's servers. Its functionality can be extended with community plugins, and it also includes Canvas, a free-form board feature.
