Just seeing the introduction, I can see this tool hardly adds any value.

The introduction video shows how easy it is to import an epub, and then "asks the ebook" to give them the Table of Contents. While the ToC was already available... no real added value compared to RAG

Thank you for your valuable input. As you say, generating a table of contents and summary alone will not be of value. Interacting with the LLM may be helpful when reading documents that are not easily understood, such as difficult technical or academic books.

I saw the ToC request as a demo of the capabilities, not a statement on the full value proposition. There are a LOT of valuable features in here that are not offered in Kindle or other ebook readers.
