Dynalist vs Obsidian
Dynalist is a note-taking app centered around infinitely nestable lists with backlinks. It features the same hierarchical structure as Workflowy, but also allows for more complex formatting and linking.
Obsidian is a Markdown-based note-taking powerhouse with excellent note-linking abilities. You can easily build and navigate whole knowledge bases with Obsidian.
