Does anyone know how to get this style?

I want it for presentations.

What tool? Miro?

I am wanting this functionality.

Notice the lines look hand drawn. The shaded area of the mindmap on top left of this image.

another screen capture showing what I want to do…

hiding (partially shading) parts of the mindmap that I am not presenting

Can you help me find the software that made this mind map?

Cheers.
