Stop flattening your thinking
Linear notes are tidy until your idea gets interesting.
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.
Write without noise
A calm desktop editor that keeps attention on the words and the hierarchy.
Import Markdown cleanly
Turn Markdown headings and lists into a proper Treetor hierarchy instead of one flat note.
The shape of serious notes
From spark to structured draft.
Treetor is built around one simple model: organize your work as a tree, then write in each node like a normal note.
Books
Keep a complete project, topic, or body of work together.
Branches
Open the part of the idea you need now, without losing the whole map.
Items
Write small, rearrange easily, and let the document grow by intention.
Keyboard-first outlining
Create, move, and reshape ideas without reaching for the mouse.
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.
Enter
Create the next item
Keep typing and press Enter to add the next thought exactly where it belongs.

Ctrl← / →
Move across branches
Jump to a parent, open a branch, or create the next branch from the keyboard.
Built for the way thinking actually flows
All the structure. None of the ceremony.
Tree-first capture
Capture ideas in the shape they actually arrive: nested, connected, and unfinished.
Desktop calm
No social feed, no browser tabs, no workspace theater. Just your thinking surface.
Local by default
Your working files stay on your machine while the app focuses on reliability.
Export-ready
Send any tree out as Markdown, Word, PDF, or a portable Treetor Pack file.
Where Treetor fits
Different shape from the tools you already know.
Not a database, not a vault
Database notes apps make every note a row. Vault apps give you a folder of flat Markdown. Treetor gives every idea a place inside a real tree.
More than an outliner
Outlining tools give you bullets. Treetor gives you outlines and a full editable document at every node — so the structure and the writing live in one place.
Calm desktop, not another tab
Treetor runs locally with a focused desktop UI and keyboard-first editing. Your trees do not live in our cloud, and your editor is not a browser tab.
No lock-in feeling
Your tree should travel.
Import existing Markdown into a real hierarchy, then export to Markdown, Word, PDF, or a portable Treetor Pack — your trees move with you, in formats your other tools already speak.
