Google Document AI
by Google
Enterprise document understanding platform with specialized processors for invoices, contracts, lending documents, and custom extraction.
Overview
Google Document AI is a cloud platform for extracting structured data from documents. It offers specialized 'processors' for different document types—from general OCR to industry-specific extractors for procurement, lending, and identity verification.
The platform combines Google's Vision API OCR with custom ML models trained on document understanding tasks. It supports both prebuilt processors and custom model training through the Document AI Workbench.
Document AI integrates with Google Cloud's broader AI ecosystem including Vertex AI, BigQuery, and Cloud Storage. It's designed for enterprise-scale document processing with features like human-in-the-loop review and processor versioning.
