Windows/Mac/Linux: There is certainly no shortage of notes apps in the world, but if you're looking for a simple disposable scratchpad with autosave functionality, FromScratch does the job. FromScratch is very simple: type in something, and it will stay there. You can close the app and reopen it, and your text remains until you delete it. It's great for those little one-off notes that you need to type in where you don't want to waste the time or effort opening up your usual notepad. It's super simple, but it's actually a nice little app to have around.
