For Indian businesses, document processing is a high-value AI use case — GST invoices, KYC paperwork, forms — but the right OCR tool depends heavily on Indian-document specifics and data residency. Here’s a grounded comparison. (dgm implements osFoundry, a separate company’s platform — dgm is an independent integration partner, not osFoundry.)
At a glance
| Tool | India angle | Note |
|---|---|---|
| Docsumo (Indian-origin) | Built-in GST/HSN/tax-rate validation on invoices | Mumbai operations; from ~$299/mo |
| Nanonets (Indian-origin) | Indic scripts; VPC/on-prem deployment | Pay-per-block; open-source toolkit |
| AWS Textract | Mumbai (ap-south-1) region → data in India | Pay-per-page; recent India price cut |
| Google Document AI | Data residency / VPC-SC / CMEK | ~$1.50/1k pages; India region — confirm |
| Azure AI Document Intelligence | Azure India regions | Free F0 tier; custom models |
(Facts per docsumo.com/pricing, nanonets.com/pricing, AWS Textract Mumbai pricing, Google Document AI. Pricing and India options change — confirm with each vendor.)
The India-specific picks
Two Indian-origin tools lead on India-document fit:
- Docsumo — built for documents like invoices, with automatic validation of GST number, HSN code, tax rate and totals. For GST-heavy accounts-payable workflows, that domain logic is a real time-saver.
- Nanonets — strong on varied Indic-script documents, with VPC/single-tenant/on-prem deployment (data kept in-boundary) and an open-source toolkit. Good where data control matters.
The hyperscalers are also credible: AWS Textract runs in Mumbai (ap-south-1) — a clean India data-residency answer — while Google Document AI and Azure AI Document Intelligence bring data-residency controls and India regions (confirm Document AI’s India-region availability and Indic-language depth at the time you choose).
Where osFoundry fits — orchestration, not OCR
Be clear on the boundary: OCR is a specialised capability, and osFoundry is not an OCR engine. The right pattern is to use a best-in-class OCR tool to extract data and have osFoundry orchestrate that output into downstream AI workflows — validating, classifying, routing and acting on it, with model-neutral reasoning and your data kept in India via self-hosting. osFoundry makes the extracted text useful across your processes; it doesn’t replace the extractor. (It’s a younger platform with limited independent coverage, so dgm validates the integration.)
Choosing for India
- GST/AP automation → favour Docsumo’s built-in tax-field validation.
- Varied Indic-script docs + data control → Nanonets (on-prem/VPC).
- Already on AWS, want India residency → Textract (Mumbai).
- Already on Google/Azure → their document services with residency controls.
Always confirm current pricing, India-region availability and Indic-language/script support before committing.
How dgm helps
dgm selects the OCR engine that fits your documents and residency needs and integrates it into an osFoundry workflow that validates, classifies and acts on the extracted data — keeping data in India via self-hosting where required. Transparent pricing: $399 assessment, $3,999/month implementation, no per-seat fees (INR approximate; 18% GST for domestic clients). Explore the platform at osFoundry, or talk to dgm about a document-AI workflow.
