Obsidian

Obsidian is a powerful, local-first knowledge base: it uses plain Markdown files for notes and links them bi-directionally to build a personal, interconnected knowledge graph.

Obsidian is a cross-platform note-taking application designed for building a 'second brain.' It operates on a local folder of plain Markdown files (a 'vault'), ensuring you own your data and maintain long-term portability. The core strength lies in bi-directional linking, which connects concepts using the `[[link]]` syntax, allowing you to visualize relationships via an interactive Graph View. With thousands of community plugins and themes, users can customize the platform for diverse workflows, from Zettelkasten to project management, making it a flexible and future-proof tool for serious knowledge workers.
