Makers, where do you scribble?

As a maker, we often scribble a lot of things. Be it an idea, some todos, any link we found on the internet, or maybe a code snippet. Most of the time I use sublime text to scribble things. What do you use to scribble something? Currently we are working on Whatnote, a browser first notepad with zero learning curve.
