Interesting, good job. I find it useful, but there are some questions (that I'm sure will be arranged in the future):
- Even if the document is in another language (in my case spanish) and the question is in this language, the response is always in english, unless you add at the end of each sentence "please, answer in spanish"
- I've found that the same question in english and in spanish gives diferent responses.
I love the idea of having the original document.
