With a tool like this, instead of waiting for a Go pro to visit our local Go club to review our kifu, I can have my game reviewed move by move until the end (not only the first n moves).

I can still have questions for pros, but they would be more specific.

Now, playing a superhuman intelligence bot can be unfun. Now matter how much effort you put in a move, you will just keep making your outcome worse with every move.

Another important use-case is that the AI can also tell you if a joseki is actually joseki, and how to refute a bad joseki move.
