Actually Dragon Ball Z Kai has all the filler episodes cut out and like 200-ish episodes are cut back to 100 or so episodes and its digitally remastered so there's new music and I think the characters were brought back to redo the voices.
Added:
Kai is a digitally remastered yes but the reason for even to redo the series was because it was considered too long and was summarized and shortened in Dragon Ball Kai.
(P.S. I fixed the grammar issues from the original answer.)
Kai Means inproved as in Dragonball Z KAI
I don't think theres a difference i think dragonball z Kai is like a repeat of dragonball z and who knows maybe they will continue the story of goku and uub.
They did, Dragon Ball Z Kai...
because dragonball z is a Japanese
Yes it is. It's remastered Japanese version of Dragonball Z. The episodes will now be cut down to 100.
I guess because I went to the internet and I was reading about that "dragonball Kai will be shown or be aird in nicktoons this may2010" but the show will be called (dragonball z Kai) but I don't know which day that the show will be on so guys when you can go to the internet you could check about or check out which day in may2010 will dragonball Kai or dragonball z Kai will come out and dragonball Kai or dragonball z Kai and dragonball z are the same thing because when you see dragonball Kai or dragonball z Kai it will be the same thing
Kai Means inproved as in Dragonball Z KAI
Dragonball GT= 64 episodes : Dragonball Z Kai= 98
The same as in Dragon ball z because it is more or less the same show.
I don't think theres a difference i think dragonball z Kai is like a repeat of dragonball z and who knows maybe they will continue the story of goku and uub.

YES there is Dragonball, Dragonball Z, and Dragonball GT, THEN *****DRAGON BALL KAI**
because dragonball z is a Japanese
Well, theres is a remake of Dragonball Z called Dragonball Kai. But there is a new season called Dragonball GT, this series is not made by Akira Toriyama(The creator of Dragonball)
because the last series in dragon boll z was dragon boll z Kai
