Hal is a chatbot assistant, not a language teacher / tutor. How would you type Kanji to Hal?
To use Hal one should get really involved with it, this forum and it's members.
There is no "turn key" AI of which I'm aware. Training any AI program takes time...weeks, months, years to achieve good results. There really is no shortcut. So your desire to have Hal be really smart right away is nice but quite out of the reach for the moment.
There are a number of good free language programs that help teach practically any language. That is what they were designed to do.
That's about as straight forward and honest as I can get.
While Hal is a pretty good chat assistant there are some limitations to what it or any other AI program can do.
Good luck!
