As I've replied to other people: No AIML. My bot uses its own markup language custom-made to its needs that I call ACUMANSCRIPT. What makes it special is the backend, which is much more flexible and advanced then AIML (which focusing on exact string matching).
In fact, ACUMAN beat the ALICE bot in the last Chatterbox Challenge by over 20 points, winning the "Best New Bot" prize.
