Keep is one of my favorite tools. It is great for note taking, making lists, and creating reminders. The best part is that it syncs between all your devices, so you can make a shopping list on your computer or tablet and the pull it up on your phone when you get to the grocery store. Of course, there are several other products that do the same or a similar thing, but now Keep has another cool feature. You can save directly to a Google Doc. Sure you could just copy and paste, but this saves a couple of steps.
