Creating More Valuable Features

I am currently working on a SaaS that is focused on helping users understand complicated documents. I have included features such as simple summaries, bulleted lists, and video recommendations, but I am struggling to come up with more features that would have value to people. I hope to one day monetize this and to do that I need people to find value in it. Any tips? Was there ever a confusing document given to you? What ways did you hope to understand it? What could a better understanding of the document help you with/prevented? Thanks in advance for any advice or suggestions. This is my first time building a project like this.
