PDF Index Generator is a powerful AI-Powered book indexing utility that automates the creation of professional back-of-book indexes. The program intelligently parses your PDF, identifies index-worthy terms, and generates a beautifully formatted index in just 4 easy steps, and in record time. PDF Index Generator has two modes to build the book index: Classic Mode, which uses smart rule-based indexing, and AI-Mode that uses Artificial Intelligence to deeply understand your book’s content, extract key terms, handle headers, sub-headers, and cross-references with a level of precision previously only possible through manual human indexing.
