Help! Can't remember name of longtail keyword/domain generator

I found a tool here over a year ago and I can't remember the name of it. I'm trying to find it on my 1TB external hard drive and have had no luck so far. Does anybody here know about a tool that will allow you to enter a group of keywords "group1" "group2" "group 3" and so on.... Then you click a button and it makes all of the possible combinations and does a check to see if they're available for registration?

Any help would be greatly appreciated. I have already done searches and I can't find it. Thanks in advance.

81 looks and nobody knows what I'm talking about?

Let this be a lesson to everyone. Label your crap so you can find it later.
