AI tool for helping create TTRPGs.

I have been looking for a free AI tool that can assist me with my TTRPG rule book. I need something that will help me organize it all into one PDF. I tried Claude, but the free service only goes so far.

I can't upload all of the files into one chat because of limitations. And I can only send so many messages before that runs out as well. I have even come back the next day to see if I could continue with the same chat, and it has the same message telling me I'm over the limit and need to open a new chat.

Unfortunately, Claude doesn't remember the previous chat. It doesn't help me to have to start over. Claude is great for uploading 1 or 2 documents and it will generate a PDF based on that information.

However, I have been unable to get all of the information I need into one document. There is always a problem with too much text that I sent, or the PDF Claude generates cuts off and I don't get all the text.
