What is Nanonets and How Does it Work?

Nanonets is an AI-powered document processing platform that automates data extraction from unstructured documents, including invoices, receipts, purchase orders, contracts, bank statements, insurance claims, and healthcare forms. It converts these documents into structured data that can feed directly into downstream systems.

The platform combines OCR with deep learning models, functioning as an intelligent document processing tool. Pre-trained models cover common document types, while more complex or custom documents require users to upload samples for AI model training, with optional configuration of extraction schemas and validation rules.

Documents can be uploaded via drag-and-drop, email forwarding, or API integration. Nanonets also integrates with business software such as Salesforce, QuickBooks, Google Drive, Zapier, Dropbox, Microsoft SharePoint, and Notion, enabling teams to route extracted data into existing workflows without custom development.

The solution serves businesses in retail, logistics, healthcare, finance, and insurance, with use cases including accounts payable automation, order processing, and insurance underwriting. Nanonets reports that a notable portion of Fortune 500 companies rely on its service.

Why Consider Nanonets Alternatives?

Nanonets performs well for organizations handling common document types, such as invoices and receipts, at moderate volumes. Its pre-trained models offer solid accuracy on standard documents, and integrations with popular business applications make it accessible for teams without deep technical expertise.

However, several limitations lead organizations to consider alternatives. Pricing can escalate quickly, with block-based charges around $0.30 per page for extraction, plus additional fees for formatting, lookups, and premium integrations, making costs unpredictable for teams scaling their document volumes.

Reliability is also a concern. Users report bugs and inconsistent processing speeds that can disrupt workflows. Complex document setups require uploading training samples and manually configuring models, demanding technical skills many teams do not possess.

Customization options remain limited compared to other solutions. Advanced features carry a steep learning curve, making it difficult to adapt the platform to non-standard documents or specialized extraction needs.

Organizations processing complex documents with irregular layouts, dense tables, or handwriting face the most significant gaps. Nanonets lacks evaluation frameworks, schema versioning, workflow orchestration, human-in-the-loop review systems, and agentic optimization capabilities critical for production-grade document pipelines.

Best Nanonets Alternatives in March 2026

Extend: Best Overall Alternative

Extend is the complete document processing toolkit comprised of the most accurate parsing, extraction, and splitting APIs to ship your hardest use cases in minutes, not months. Extend's suite of models, infrastructure, and tooling is the most powerful custom document solution, without any of the overhead. Agents automate the entire lifecycle of document processing, allowing your engineering teams to process your most complex documents and optimize performance at scale.

Key strengths:

• Near-human accuracy (99%+) on complex documents with tables, handwriting, signatures, and checkboxes
• Agentic optimization via Composer that automatically experiments with schema variants to maximize extraction accuracy
• Evaluation suite with automated accuracy reports, custom scoring, and continuous improvement loops
• Schema versioning and workflow orchestration with conditional routing based on confidence thresholds
• Built-in human-in-the-loop review UI for corrections that feed back into evaluation sets
• Multiple performance modes (fast parsing, cost-optimized parsing, fast extraction) for different use case requirements

Organizations processing mission-critical documents need more than basic extraction—they need evaluation frameworks to measure accuracy, schema versioning to evolve safely, and workflow orchestration to route documents intelligently. Extend ships with all of these capabilities built-in, while Nanonets requires teams to build custom infrastructure around a basic extraction API.

Pulse

Pulse is a production-grade document extraction service designed to convert PDFs and images into markdown or HTML, with optional structured JSON output via schemas. The platform also provides bounding boxes and webhooks for asynchronous jobs, enabling integration into complex workflows.

The service offers strong extraction capabilities, including schema-based JSON output, synchronous and asynchronous extraction endpoints with job polling and webhooks, markdown and HTML output with bounding-box coordinates, and multilingual OCR support. Its key limitation is the lack of a built-in evaluation framework, workflow orchestration beyond callbacks, schema versioning, or a human-in-the-loop review interface. Organizations requiring regression testing or conditional routing must implement state machines around the extraction endpoint themselves.

Reducto

Reducto is an OCR API built for teams that need reliable document parsing and text extraction capabilities across a wide range of document types, including PDFs, scanned images, and other structured or unstructured formats. Its focus is on providing a straightforward API for extracting textual content efficiently, making it suitable for applications like basic data ingestion, content indexing, or lightweight document analysis.

Its key limitation is that it offers a single processing mode for parsing, extraction, and splitting, regardless of specific use case requirements. The platform also lacks agentic capabilities, evaluation tools, schema versioning, fast or cost-optimized modes, intelligent merging strategies, and human-in-the-loop review functionality.

4. Amazon Textract

Amazon Textract is AWS’s managed OCR service that extracts text and structured data from scanned documents, forms, and tables. It integrates seamlessly with the AWS ecosystem and offers signature detection, all on scalable cloud infrastructure.

A notable drawback is that it is tied to the AWS ecosystem and requires configuration and development effort to build complete document pipelines. The platform lacks schema versioning, a built-in evaluation framework, and workflow orchestration beyond basic extraction capabilities.

Rossum

Rossum is an intelligent document processing solution specializing in accounts payable automation with AI-powered data extraction focused on financial documents. The service includes human-in-the-loop validation workflows and integration with accounting and ERP systems.

It's pre-built templates and workflows are optimized for AP/invoice processing, making customization for other document types or industries more difficult. Teams working outside financial document automation may find the service too specialized for broader document processing needs.
