What is Nanonets?

Nanonets is a general-purpose AI and machine learning platform that offers intelligent document processing (IDP) capabilities. The platform is designed for developers and enterprises who want to build custom document automation solutions using APIs.

Nanonets provides pre-built models for common document types, but its real strength is in custom model training. Organizations can train models on their specific document formats, which makes it powerful for unique use cases.

Nanonets Platform Overview

API-first platform designed for developers
Custom model training capabilities
Pre-built models for various document types
Enterprise-focused with Fortune 500 clients

For software companies building document processing into their products, Nanonets offers flexibility and power. But for accountants and bookkeepers who simply need to convert bank statements, the developer-focused approach creates unnecessary complexity.

Developer Platform vs Accountant Tool

Nanonets is built for software engineers. Zera Books is built for accountants.

API Integration Required

Nanonets expects you to integrate via API, write code, and manage workflows programmatically. Most accountants just want to upload a file.

Technical barrier

Model Training Needed

Even with pre-built models, you often need to train custom models for your specific bank formats or document layouts.

Learning curve

Configuration Complexity

Setting up extraction rules, validation logic, and output formatting requires technical expertise and time.

Setup overhead

Weeks to Deploy

Between API integration, model training, and testing, it can take weeks before you process your first real statement.

Slow time-to-value

No Accounting Workflows

Nanonets extracts data but does not understand accounting. No auto-categorization, no QuickBooks mapping, no reconciliation features.

Missing features

Per-Page Pricing

Nanonets charges $0.10-0.30 per page. Processing 1,000+ pages monthly gets expensive fast, especially during tax season.

Cost scales with volume
