Analyze knowledge-heavy books, educational PDFs/EPUBs, nonfiction works, and long articles into evidence-based layered concept statistics, concept maps, argument chains, review cards, critical applications, and a Guofulun-style interactive visual HTML report. Use this whenever the user asks to analyze, quickly understand, reopen, or preserve a knowledge-book/long-article analysis, especially when concept frequency, keywords, theory models, or book knowledge maps matter.
