Both. As a player, you can have in front of you cards for all your powers and your items; you can customize them and mark the powers that you've used.This tool looks very interesting, although I'm not sure how i woudl use it. Is it intended as a tool for players, DMs or both?
As a DM, it's very handy to have all the cards for the monsters in an encounter. Much easier and faster than having to cut and paste from the Compendium.
