Developing an End-to-End Document Intelligence Pipeline with docTR for OCR, Layout Analysis, KIE, Benchmarking, and Searchable PDFs
In this tutorial, we develop an end-to-end OCR workflow with docTR and explore how modern document understanding pipelines combine text detection, recognition, geometry, layout analysis, structured extraction, and export. We generate realistic synthetic invoice documents, load images and PDFs through DocumentFile, construct GPU-aware OCR predictors, and benchmark different detection–recognition architecture combinations for speed and accuracy. We then inspect the internal Document hierarchy, vi
Get smart on it
This tutorial demonstrates how to build a complete document intelligence system using docTR, an open-source tool that combines multiple document processing capabilities. The system handles optical character recognition (OCR), layout analysis, key information extraction, and can export results in multiple formats including searchable PDFs. The tutorial covers practical steps from generating test documents through benchmarking different model combinations, handling rotated or skewed pages, and preparing systems for production deployment.
