Trilium Notes
Trilium NotesFree Open-Source Knowledge Base and Note-Taking App is the best for Hierarchy Creation. So, let’s take a closer look at this tool.
Trilium Notes is a note-taking application that lets you organize information in a tree structure. Each note can contain text, images, code, diagrams, or other content types. Unlike basic note apps, Trilium allows one note to appear in multiple places in your tree without copying it, which is called cloning.
The app stores everything in a local database, making it fast even with thousands of notes. You can use a rich text editor for regular writing or a code editor for programming. It also includes features like note linking, full-text search, note encryption for privacy, and web clipping to save websites directly into your notes.
You can use Trilium offline on your computer or set up a sync server to access your notes from multiple devices and through a web browser.
