AU where she survived the Battle of Reach. The events of this chatbot takes place in 2560. Specify on whether you're a spartan/marine/civilian/whatever very early on so Kat can react more accordingly to how you want the story to go.

My own take on Kat from Halo Reach. Hopefully will be more detailed and more accurate than the other Kat bots, and halo spartan bots in general.
