I didn't do any extensive testing but seems to be really useful. However, where can we see the privacy policy? People are probably going to upload some important and confidential documents so it's good to know how this data is being handled. The only thing I see is an asterisk after the 24 hour notice Also, the bot answer window may have 5 pages even if 1 page is enough for the answer, this may confise your users since they may think there's something else on other pages
