Our verdict: Choose Amazon Textract when your entire infrastructure runs on AWS and you need a document scanner that plugs directly into your existing cloud workflows.

Nanonets specialises in building custom AI models for specific document types—whether that's a unique invoice format, a proprietary medical form, or a niche legal document. Its no-code training interface allows business users to train models on their own documents without machine learning expertise. For teams with highly specialised or non-standard document workflows, Nanonets offers the most flexibility.

Where it wins: The ability to train a custom extraction model on as few as 50 documents makes it uniquely powerful for niche or proprietary document formats.

Where it struggles: Its pricing starts higher than per-page alternatives, and the need to train custom models adds setup time compared to out-of-the-box solutions.

• Teams with unique document formats
• Operations managers needing no-code training
• Mid-market businesses with specialised workflows

Pricing: from $499/month — Check latest pricing at Nanonets →

Our verdict: Select Nanonets if your documents don't fit standard templates and you need a no-code way to train a highly accurate custom extraction model.

Hyperscience is an enterprise document processing platform that combines AI-powered extraction with a sophisticated human-in-the-loop verification system. It is designed for large organisations where data accuracy is critical and errors have compliance or financial implications. Hyperscience excels at handling exceptions and low-confidence extractions by routing them to human reviewers within the same platform.

Where it wins: Its built-in human-in-the-loop workflow ensures near-perfect accuracy on critical documents, making it ideal for regulated industries like finance and healthcare.

Where it struggles: The platform is enterprise-only with custom pricing, making it inaccessible for small teams, and its setup requires significant professional services engagement.

• Large enterprises in regulated industries
• Finance and insurance back offices
• Healthcare document processing

Pricing: Custom — Check latest pricing at Hyperscience →

Our verdict: Choose Hyperscience when you need the highest possible accuracy on critical documents and have the budget and scale to justify an enterprise-grade platform.

Rossum is a specialised AI document scanner focused on financial documents—invoices, purchase orders, and receipts. Its AI is pre-trained on millions of financial documents, achieving high accuracy on line-item extraction, tax calculations, and vendor data. For accounts payable teams, Rossum offers the most purpose-built solution with direct integrations into major ERP systems like SAP, Oracle, and NetSuite.

Where it wins: Its specialised focus on financial documents means it extracts line items and totals with higher accuracy than general-purpose scanners, reducing manual reconciliation work.

Where it struggles: It is narrowly focused on finance documents, so it is not a good fit for general-purpose document scanning or non-financial document types.

• Accounts payable departments
• Finance teams processing invoices
• ERP-connected document workflows

Pricing: from $500/month — Check latest pricing at Rossum →

Our verdict: Opt for Rossum if your primary document scanning need is invoice and purchase order processing and you want a purpose-built solution that integrates with your ERP.

This insight from enterprise architects highlights a crucial reality: even the most accurate scanner fails if it creates workflow friction. Prioritise tools that fit your existing stack.

A common mistake is selecting an enterprise platform for what turns out to be a simpler need. Start with a free tier or trial on a representative sample of your actual documents.

Nanonets and similar platforms promise custom models, but the training data requirement is often underestimated. Pre-trained models from Google or AWS may deliver 90% of the value with zero setup.
