Trilium Notes is a personal knowledge base for organizing notes in a hierarchical tree while also supporting cross-linking between notes. It combines a fast web UI, rich editing (including code and Markdown), and powerful search to manage large, interlinked knowledge collections.

Key Features

  • Tree-structured notebooks with cloning (same note in multiple places)
  • Rich-text (WYSIWYG) editing plus code notes with syntax highlighting
  • Markdown import/export and other bulk import/export options
  • Bidirectional links and backlinks; note relations/attributes and tagging
  • Full-text search with filtering to navigate large note collections
  • Versioning/revision history for notes
  • Web clipper for capturing content into notes
  • Scripting/automation (JavaScript) and custom widgets for extending behavior

Use Cases

  • Personal knowledge management (Zettelkasten-style linking, research notes)
  • Technical documentation and “second brain” for projects (snippets, runbooks)
  • Journaling and structured life logs organized by a timeline/tree

Limitations and Considerations

  • Collaboration features are limited compared with team-first tools (e.g., comments, real-time multi-user editing)
  • The data model (tree + clones + attributes) can require a learning period for new users

Trilium is well-suited for users who want a fast, local-first feeling knowledge base with a strong hierarchy, links, and extensibility. It is commonly used as a private alternative to commercial note and knowledge apps while retaining advanced organization and automation capabilities.
