Preserving document structure when preparing PDFs for an AI assistant At PwC, I evaluated and combined document-processing tools for an AI assistant that answers public enquiries using a client’s documents. I built an ingestion pipeline that prepares those documents for retrieval while preserving the relationships an answer may depend on, including table structure, cross-page references and the branches of a flowchart. End-to-end tests and deployment analysis informed the solution I recommended to the client.
