hardly the same app. I'm in both the AI and machine learning classes and while one has a full infra-structure for programming assignments and some other video-playback that I haven't seen anywhere else, the other one uses youtube videos with quizzes only at the end of the videos.

The AI class seems to be the exception. The AI class has a .com extension, while all the others have .org extensions. The AI class website runs on KnowLabs software, while all the others run on software developed by some Stanford students last summer.

Thank you for your work. I am in both the AI and the ML classes, and having some work that we actually do stuff, is a great learning aid and I wish the AI course had something similar too.
