Solid questions, you've clearly been burned before lol. 1) Document revisions can be a bit hard to handle, but we currently look for any dates or document numbers present, and when possible we just show the latest. However, plenty of times there are no dates OR revision numbers, and we'll get different documents from multiple sources. In this case we show all the documents, and have prompted the AI to flag this risk to the user if the question is answered differently between documents. Not the ideal approach, but working with what we're getting...

2) Hmm, not really. You can share the chat, and the specific response, but the only way to export the source would be to screenshot it... Adding it to our list of potential next features!
