Copilot and large documents

I have a very large document.  It is over 67000 words and over 200 pages.  I tried to use the embedded copilot and it is worthless.  The response time when it responds to a conversation is minutes.  The response is one word at a time.  It can take 5-10 minutes to repeat a long paragraph.  I have used the free copilot app and copy/past back and forth.  This works great until my conversation is truncated.  Then copilot loses context around my document and the responses become almost useless without telling it what to do word for word.  I am writing a novel.  After truncation, it does not know any character names.  Their personalities, anything.  I get tons of sequence errors and logic issues.  I can use it for a few days and get it working great.  Then the conversation is truncated and I have to start over again.  I tried attaching my document to the copilot app.  I get a message that the content is too dark.  It is about a young girl who is burned in a fire and how she succeeds after that.  No cusswords, no graphic sex.  Just the scene of escaping from a fire and getting burned.  I really am not finding copilot as useful as it could be if I had space to save conversations.

    I have figured out a way to move forward.  I had to go back to the regular copilot App.  I stored my content in pages.  I will probably end up with about 40 pages.  I have found out I can have Copilot refer to a prior page.  That helps with Sequence and helps to keep some of the context for Copilot.  Just a heads up to anyone using the copilot app.  I encountered a bug in copilot.  Probably a fluke.  But while processing one of Copilots responses only got half way done.  It came back with half a page highlighted.  I tried reopening Copilot and rebooting.  Still highlighted.   Issued a new conversation to clear it.  But I lost half of my page content.  Good thing I was pasting into Word all along, so I was able to recover.  But it could have been bad if I did not have things backed up.

    • If you have an M365 Copilot license, try Copilot Chat. https://m365.cloud.microsoft/chat
      Put your document in a folder in your OneDrive or SharePoint. Switch the chat to "Work," enable GPT-5 in the top right corner, and start your conversation with Copilot. This should work.
