AI Book Chapter Update System
Automatically research, review, and update technical book chapters while preserving equations, figures, references, and formatting.
An AI-powered document processing system designed for publishers to maintain and update technical and scientific book chapters. Users can upload DOCX or PDF chapters, identify outdated factual claims, research authoritative sources, review proposed changes, and selectively apply approved updates. The system is designed to preserve the original document structure and formatting, including mathematical equations, equation numbering, figures, tables, symbols, references, and cross-references. It also provides an auditable change history, public-domain image suggestions, and export of fully editable DOCX documents.

What we built
An AI-powered document processing system designed for publishers to maintain and update technical and scientific book chapters. Users can upload DOCX or PDF chapters, identify outdated factual claims, research authoritative sources, review proposed changes, and selectively apply approved updates. The system is designed to preserve the original document structure and formatting, including mathematical equations, equation numbering, figures, tables, symbols, references, and cross-references. It also provides an auditable change history, public-domain image suggestions, and export of fully editable DOCX documents.
Where it started
Technical and scientific books require frequent updates as factual information, standards, research, and technical references change. Updating these chapters manually is time-consuming and creates a significant risk of damaging the original document structure, equations, references, and formatting. The system needed to automate the research and update process while keeping a human reviewer in control of every proposed modification.
How we solved it
We designed a modular AI document-processing architecture that separates document ingestion, AI analysis, research, human review, selective updates, renumbering, audit logging, and document export. LangGraph orchestrates the AI workflow while specialized document-processing tools handle DOCX/PDF extraction, mathematical equations, formatting preservation, and document reconstruction.
