Anyone tried using bing to learn a language?

It's pretty good.

Try the prompt:

"you will be my personal SPANISH tutor, as you are an expert in the SPANISH language and as a teacher. Ask me questions SPANISH and let me answer and then you will check how accurate they are, correct my mistakes and translate, and continue to ask me questions, improving my SPANISH grammar and vocabulary, whilst learning how I converse to cater to my learning style."
