A place for every idea
Break a complex topic into books, branches, and items instead of flattening everything into one long note.
Hierarchical information app
Organize complex information as a living hierarchy.
Treetor gives your notes a real parent-child structure: trees, branches, text items, and picture items that can be rearranged as your understanding changes.
Built for people searching for hierarchical information app, hierarchical notes, structured information, knowledge hierarchy, tree structure notes, and better ways to organize complex ideas.
Why it works
Hierarchy should be easy to create and easy to change.
Structure stays editable
Promote, demote, reorder, duplicate, and merge items when the shape of the work changes.
Words and evidence together
Mix text items with captured or imported picture items, then export the result when it is ready to share.
Structured knowledge
More structured than notes. More focused than a canvas.
Built for information that has shape
Projects, research, procedures, product plans, and learning notes usually are not linear. Treetor treats hierarchy as the primary model, so users can keep context visible while drilling into detail.
Keyboard-first restructuring
Hierarchy should not feel locked after you create it. Use keyboard shortcuts to move items up or down, indent them under another item, or outdent them back to the parent level.
Where Treetor fits
A practical alternative to flat or rigid tools.
| Compared with | What Treetor gives you |
|---|---|
| Flat notes | Nested relationships are first-class, not simulated with headings. |
| Folders | Branches can be rewritten and rearranged inside the editor, not managed as external files. |
| Mind maps | You get structured thinking without losing fast keyboard editing and export-friendly text. |
