About:
Octarine is a Markdown-based note-taking application designed for developers and technical writers. It provides a distraction-free writing environment with powerful features like bidirectional linking and code block execution. The app stores all notes locally as plain text files, ensuring data portability and long-term accessibility.
Key Features:
  • Bidirectional linking for building a personal knowledge base
  • Live code block execution within notes
  • Local-first storage using plain Markdown files
  • MathJax support for mathematical notation
  • Extensible via JavaScript plugins
Use Cases:
  • Creating a connected 'second brain' or Zettelkasten system
  • Technical documentation and software development notes
  • Research paper writing with integrated code and equations
Alternatives:
  • Obsidian – Similar core concept but Octarine is open-source and focused on code execution
  • Notion – Cloud-based with proprietary format; Octarine is local-first and uses standard Markdown
  • Typora – WYSIWYG Markdown editor; Octarine adds linking and plugin capabilities
