LLM-augmented extraction

Using a large language model to extract structured fields from documents — particularly effective on layout-free documents where template-based OCR fails.

Definition

What LLM-augmented extraction means in practice

LLM-augmented extraction uses an LLM to convert document text into structured fields. The classical alternative — template-based extraction with field coordinates per layout — works on standardised forms and collapses on the layout-free document types (contracts, correspondence, free-form claims) that make up the long tail of enterprise document volume. LLM extraction is robust to layout variation because it reads the document the way a human would. The engineering pattern is to prompt the model with the target schema, return the extracted fields plus a per-field confidence score, and route low-confidence fields to human review. MindMap's DocGenie and DocuMage are the two products that ship this pattern in production.
