I've created a web-based editor for ASCII file directory trees called asciitreeman. It's designed to make it easier to edit and reorganize the output of the tree command.
You can try it out here: https://reorx.github.io/asciitreeman/
And the source code is on GitHub: https://github.com/reorx/asciitreeman
Some of the key features include visual tree editing with drag-and-drop-like operations, real-time sync where changes are immediately reflected in the ASCII output, keyboard shortcuts for navigation (J/K or arrow keys), and auto-saving your work to local storage.
What's interesting is that I used Claude Code to "vibe-code" this project in a very short amount of time. It was a fun experiment in AI-assisted development. For those curious about the process, I've included the prompts and specifications I used in the source code. You can check them out in the spec.md and CLAUDE.md files in the repository.
Hop you find it useful!
