đĄ Our Take
Choose Nanonets if you want a turnkey solution with built-in workflow automation, a review interface, and native ERP integrations without building custom pipelines. Choose Google Document AI if you're already invested in the Google Cloud ecosystem, prefer per-page pricing, and have engineering resources to build custom processing workflows on top of the extraction API.
Google Document AI - Pros & Cons
Pros
- âIndustry-leading OCR accuracy leveraging Google's text recognition technology from Lens and Photos
- âSemantic entity extraction that understands document types and field relationships, not just key-value pairs
- âProcessor-based architecture makes it easy to add specialized document understanding without custom training
- âCompetitive free tier (1,000 pages/month) for evaluation and small-scale production
Cons
- âGoogle Cloud dependency with significant setup overhead (project creation, API enablement, IAM configuration)
- âSDK support is primarily Python and Node.js â less multi-language coverage than Azure's document services
- âDocumentation organization and example quality has historically lagged behind Azure and AWS equivalents
Nanonets - Pros & Cons
Pros
- âPre-trained models for many common document types enable fast deployment without extensive setup or training data
- âNo-code workflow builder allows non-technical users to create complex approval chains and routing rules

- âBroad integration ecosystem including native connectors for major ERPs and thousands of apps via Zapier
- âSupports 40+ languages and handles handwritten text, tables, and multi-page documents
Cons
- âCustom model training requires a minimum of 50 annotated samples, which can be time-consuming for highly specialized document types
- âPro plan pricing at $499/month may be steep for very small businesses with moderate document volumes
- âOn-premise deployment is only available on Enterprise plans, limiting options for security-sensitive smaller organizations
- âExtraction accuracy on heavily handwritten or degraded-quality documents can require significant human review
