FileOutliner

FileOutliner is a local-first Markdown note app with an outliner editor:

1. Notes are edited in an outliner (infinite-list) experience inspired by WorkFlowy and Logseq.
2. Notes stay as plain .md files in your workspace, so they remain easy to manage with Git or any editor.

Why FileOutliner

• Local Markdown files (no database lock-in)
• Outline-first editing with collapsible node tree
• File-tree workspace navigation with fast note switching
• Toggle between Outliner mode and Source code mode
