Branch naturally
Capture a thought, press a key to add or move the next item, and keep going.
Hierarchical text editor
Think in trees. Write in text.
A focused desktop workspace for notes, outlines, research, and plans that need more structure than a blank page can give — now with Markdown import that turns headings and lists into properly hierarchical Treetor notes.
Built for people whose ideas have branches.
Stop flattening your thinking
Treetor keeps the speed of plain text, then adds the missing shape: books, branches, and items you can grow. Bring in existing Markdown files and keep their structure as clean, navigable Treetor notes.
Capture a thought, press a key to add or move the next item, and keep going.
A calm desktop editor that keeps attention on the words and the hierarchy.
Turn Markdown headings and lists into a proper Treetor hierarchy instead of one flat note.
The shape of serious notes
Treetor is built around one simple model: organize your work as a tree, then write in each node like a normal note.
Keep a complete project, topic, or body of work together.
Open the part of the idea you need now, without losing the whole map.
Write small, rearrange easily, and let the document grow by intention.
Keyboard-first outlining
Treetor is designed for the moment when your thinking is moving faster than your hands. Add new items, reorder them, promote or nest them, and move between branches with direct keyboard bindings.
Keep typing and press Enter to add the next thought exactly where it belongs.
Move the current item up or down as your outline changes shape.
Shift an item higher or deeper in the tree without breaking your writing flow.
Jump to a parent, open a branch, or create the next branch from the keyboard.
Why it sells itself once people try it
Create new items, move them up or down, and change depth with dedicated shortcuts.
Capture ideas in the shape they actually arrive: nested, connected, and unfinished.
No social feed, no browser tabs, no workspace theater. Just your thinking surface.
Your working files stay on your machine while the app focuses on reliability.
Move from structured notes to shareable Markdown, Word, PDF, or Treetor Pack files.
Save or share a complete editable tree as a portable TPack file with the .tpack extension.
No lock-in feeling
Treetor keeps the authoring experience structured from both directions: import existing Markdown into a real hierarchy, then export to familiar formats or a portable Treetor Pack — TPack for short.
