Uploading and downloading doc

Please add the ability to upload (and read) documents such as docx and pdf, to upload changes or additions in docx and pdf, and the ability to generate docx and pdfs for the user to download. These are some of the most basic abilities an application like this should have. Do you know how much of a pain it is to have to piece by piece paste the contend of a 120,000 word manuscript and then have to copy and past in Word from chats the final manuscript piece by piece? I am completely shocked you do not have this very elementary and basic feature. I have never seen an ai chat with book writing capabilities that cannot do those things. This is a major issue and is desperately needed.
