## What is KnowTree?

◆ Organize notes in a "hierarchy" — and everything becomes clearer

With most note-taking apps, as information piles up,
it becomes hard to see how things are connected.

"KnowTree" organizes your notes hierarchically
with parent-child relationships.
Group related information together so you can always find it again.

◆ Key Features

[Tree Structure]
Create nodes with parent-child relationships.
Organize like "Main Topic → Subtopic → Details."
No limit on how deep you can go.

[Flexible Workflow]
Start from the big picture (top-down),
or jot down small notes and group them later (bottom-up) —
both approaches work great.

[Rich Content]
Supports Markdown, images, links, and code blocks.
Create notes that are clear and easy to read.
