The AI assistant does not read PDFs

#1

Hi everyone. I have some marketing books that I want to upload into a knowledge base and then integrate into an AI assistant so that it can help me improve my texts based on the content of those marketing books. But I can’t seem to get the AI assistant to read the books! It keeps responding with things like, “Unfortunately, I couldn’t find specific information on persuasion methods or the most common objections from the available sources. However, we can work together to develop a more effective outline based on these guidelines.”

I’ve tried several approaches: uploading all the files into a single KB, uploading one large PDF containing all the books into a KB, and even creating a separate KB for each book and setting it up as a tool (Knowledge Base Query) in the AI assistant, but it simply refuses to read the contents of the books. What am I doing wrong?
