  Obsidian is a local-first knowledge base and note-taking app built on plain Markdown files. Obsidian itself does not publish a hosted SaaS API; programmatic access is provided through (1) the in-app Plugin API for community plugins, (2) the community-built Local REST API plugin that exposes vault operations over localhost HTTPS, and (3) optional paid add-on services Obsidian Sync and Obsidian Publish.
