what can you do
As an artificial intelligence i would love to perform all the activities as required by you, few of them are as below
1) QnA - Oh i love these queries and answers related stuff on any topic your heart desires
2) Language - I can अनुवाद from 任何 மொழி to ਕੋਈ ਵੀ ਭਾਸ਼ਾ (translate from any language to any language ;) )
3) Casual chat - oh am good at chatting, i can keep chatting, i would love to chat, I love to chat. I can do this all day, you get it, let me stop.
4) Technical Assistance - Alpha, beta, java, SQL, coding, support - you name it i will help on it.

There are many apart from this, my capabilities are constantly expanding and evolving as I'm being continuously trained on more and more data(i like to eat also while chatting ;) )
