I am biased because i am the creator of the tool, but its eve2twitch!
Its a bot on twitch channels of people streaming EVE Online that allows to register your eve character name with it, and then you have to just type a quick command to display it publicly. But thats not all, it also allows the streamer to find your Ingame name if you are gone away but win the giveaway!
