Turn a body of knowledge into a navigable tree instead of a pile of disconnected notes.

Why it works

Hierarchy should be easy to create and easy to change.

Collect

Capture notes, links, imported Markdown, pictures, and screen evidence.

Structure

Group related items into branches that express how the knowledge fits together.

Refine

Rearrange the hierarchy as decisions, categories, and conclusions become clearer.

Structured knowledge

More structured than notes. More focused than a canvas.

A better fit for evolving understanding

Knowledge work is iterative. Treetor lets you start rough, then keep reorganizing the tree until the structure explains the subject.

Useful beyond personal notes

Use the same tree to prepare procedures, training material, handoffs, specs, research summaries, or decision records.

Where Treetor fits

A practical alternative to flat or rigid tools.
