Note: Blender 5.2 ships with a built-in Bevel node, this one is for 5.1.
Like the Bevel Modifier
Similarly to how the bevel modifier works, this system allows you to change the Width of the bevel and the Angle of the edges you want to bevel.

It works fine for a lot of shapes, but be aware that it doesn't account for everything. For example it may produce strange artifacts when the edges of the main mesh have a big angle value.
