What is Obsidian?
Obsidian stores notes as Markdown files in a local folder, linked into a personal knowledge graph. A plugin ecosystem of thousands extends it into tasks, spaced repetition, canvases, and more. Free for personal use (including commercial contexts since 2023), with paid sync and publish services.
