Is there a desktop app like sketch.io?

Question

Windows

Or maybe there are Photoshop brushes that mimic pencil drawing?
I found these on Google, but they are too uniform, there are no random gradients of transparency, thickness, etc., as in real pencil drawing.

Answer 1

Artrage at least.
But he is imprisoned for a graph tablet.
Possibly also an AutoDesk SketchBook .
Well, you can see more from the list .
