Would help us to know more about the specific use case and goal you had in mind. For now, generically speaking, I use OneNote for keeping track of my own generated ideas and pasting in things from other sources. For larger media I recommend having a network drive or using Dropbox. I'm happy with OneNote. For my more technical ideas where I'm brainstorming I have a nice leather journal (no lines) that I use for brainstorming. I tried using a Surface Studio as well with the pen and that works good too because you have an infinite canvas and can move things around. With paper / whiteboard brainstorming I frequently run out of room. Digital means I can just drag a bunch of stuff to make more room. Plus having the pen and choosing different colors makes it really freeform.
