Affinda stands out as a leading alternative because it is built specifically to extract any information from any document with industry-leading accuracy. Its AI agents learn instantly from every interaction and can be set up in minutes, not months. For teams looking for a faster, more flexible and more accurate way to automate document workflows, Affinda provides a document-first platform that is built for scale and ready to plug into existing systems with minimal effort.
Nanonets offers an AI-powered document automation platform with OCR, prebuilt models and no-code workflows, making it easier for teams to set up extraction for common documents such as invoices, receipts and ID cards. It is well known for its self-service interface and cloud-based deployment, which helps organizations move away from fully manual processing.
Affinda is a strong alternative to Nanonets because it delivers fast setup, industry-leading accuracy and flexible automation without relying on heavy configuration or complex workflow design. Affinda can process any document in any format, learns instantly from every interaction and uses AI agents and model memory to build reliable extraction models in minutes, not months. It also provides classification, splitting, field detection and data transformation in a single platform, giving organizations a faster, more flexible and more accurate way to automate document workflows at scale.
Nanonets delivers solid extraction accuracy across many structured and semi-structured documents. It is suited to scenarios where document formats are reasonably consistent and where users can invest in tuning specific flows for invoices, receipts or other recurring document types.
Affinda is designed to deliver industry-leading accuracy even when document formats are not consistent. Its AI agents combine advanced language models with proprietary reading algorithms and model memory to extract information reliably from structured, semi-structured and unstructured documents, including complex tables and multi-column layouts. Because Affinda learns instantly from every interaction, it continues to improve without lengthy retraining cycles, giving organizations a more flexible, resilient alternative to template or model-specific setups while enabling straight-through processing and reducing manual review.
Affinda is designed for very rapid deployment. You can upload a single document and begin automating end-to-end processing almost immediately, without building templates or complex workflows. Its AI agents handle classification, splitting, field detection and data transformation out of the box, so teams can move from initial setup to production in days rather than months. This speed gives organizations a faster path to value when compared with more configuration-heavy approaches.
Affinda minimizes setup effort by reducing the configuration work for your teams, whilst still offering a no-code interface for your more business needs. There is no need for large labelled datasets, extensive rule building or repeated model training cycles. Affinda lets you build accurate extraction models in minutes, not months: upload documents, indicate the information you want and the platform's AI agents and model memory take care of the rest. This creates a faster, smarter path to high-accuracy automation and reduces the long-term maintenance overhead that can come with no-code training workflows.
Nanonets supports many commonly used business documents, including invoices, receipts, purchase orders, ID documents, bank statements and other structured or semi-structured formats.
Affinda can handle all of these document types and extends that capability to even more complex, unstructured and varied formats. The platform processes any document in any format, including PDFs, scanned images, handwritten forms, structured templates, unstructured layouts, nested tables and multi-page document packs. Its AI agents read text, understand context and extract information without relying on rigid templates, so even non-standard or messy documents can be processed with confidence. Because Affinda learns instantly from every interaction, it adapts quickly to new document types without heavy configuration or retraining.
Common document types our customers use Affinda for include:
Nanonets is effective for many structured and semi-structured documents, and it offers template-free marketing that emphasizes flexibility. In practice, achieving strong performance on entirely new or unusual layouts can still require additional training data, configuration and iteration, particularly where documents do not resemble previously seen formats.
The Affinda platform is designed to process new or unfamiliar document layouts with minimal intervention. Its AI agents have an advanced understanding of document layout and reading order, allowing them to interpret structure, context and positional cues with precision. This means Affinda can extract information accurately even when documents vary significantly from one file to the next. With model memory that learns instantly from every interaction, Affinda adapts to new formats without disrupting existing performance, giving teams a faster, more scalable way to process unstructured, complex or completely unfamiliar layouts while maintaining consistently high accuracy.
Organizations using Nanonets today typically have workflows built around cloud-based APIs, no-code dashboards or embedded automation. Transitioning away from this setup can seem challenging, particularly when document processing is tightly integrated into finance, operations or customer support processes.
Affinda is designed to make that switch straightforward. It plugs directly into existing workflows via APIs and integrations, accepts the same common document formats and outputs structured data in formats your downstream systems recognize. You can upload your current documents and begin automating extraction in minutes, not months, without rebuilding templates or recreating complex rules. With transparent onboarding and AI agents that learn instantly from every interaction, organizations see value quickly and avoid the lengthy configuration and maintenance cycles that often accompany platform migrations.
