Google Document AI

Managed document parsing on Google Cloud, from OCR to generative-AI custom extractors.

About

Google Document AI is Google Cloud's managed document processing service. It offers a ladder of processors: Enterprise Document OCR at $1.50 per 1,000 pages for plain text extraction, Document Layout at $10 per 1,000 pages, Form Parser at $30 per 1,000 pages, and specialized processors for invoices, receipts, lending, procurement, and contracts at around $0.10 per page. The first 1,000 OCR pages per month are free, plus a 90-day $300 cloud credit trial for new accounts. Document AI Workbench lets teams build custom extractors powered by generative AI — creating a processor is free, training is free, and you pay only for prediction — with fine-tuning for high layout variation. It suits engineering teams already on GCP who want extraction as an API rather than a standalone platform. Watch the per-page cost of specialized processors: at $0.10 a page, high volumes get expensive fast compared with the flat OCR rate.

What it can do

  • Enterprise Document OCR
  • Pre-trained processors for lending, procurement, contracts, invoices
  • Custom Extractor with generative AI
  • Custom classifier and splitter
  • Fine-tuning for high layout variation
  • Confidence scores per field

Setup

  1. Enable the Document AI API in a Google Cloud project.
  2. Choose a pre-trained processor (OCR, Form Parser, Invoice, Lending) or create a custom extractor in Workbench.
  3. Send documents via the API and receive structured output with confidence scores.
  4. Wire results into your application or data warehouse.

Prerequisites

Google Cloud account; developers comfortable with REST APIs; budget for per-page prediction costs at volume.
