Trilium Notes is a hierarchical note taking application with focus on building large personal knowledge bases. See screenshots for quick overview:

• Notes can be arranged into arbitrarily deep tree. Single note can be placed into multiple places in the tree (see cloning)
• Rich WYSIWYG note editing including e.g. tables and images with markdown autoformat
• Support for editing notes with source code, including syntax highlighting
• Fast and easy navigation between notes, full text search and note hoisting
• Seamless note versioning
• Note attributes can be used for note organization, querying and advanced scripting
• Synchronization with self-hosted sync server
• Strong note encryption with per-note granularity
• Relation maps for visualizing notes and their relations
• Scripting - see Advanced showcases
• Scales well in both usability and performance upwards of 100 000 notes
• Touch optimized mobile frontend for smartphones and tablets
• Night theme
• Evernote and Markdown import & export
