G2 reviewers note Base64.ai's user interface is not the most polished and some find documentation lacking. The platform is primarily API and integration-focused with less emphasis on the business rule validation and document workflow automation layers that operations and finance teams need.

Which OCR works best for you?

Designed for SaaS platforms, ERP systems and document-heavy operations that require precision, scalability and control.

Both tools solve real document processing problems, but for different workflows. Choose Nanonets if your team needs an end-to-end document automation platform covering invoices, receipts, POs, and contracts with a pay-as-you-go model and a strong focus on workflow integration. Its pre-trained accuracy and broad document coverage suit teams processing standard business documents at variable volumes. Base64.ai is the stronger choice if you need the widest possible document type coverage worldwide with sub-3-second processing, built-in fraud detection, and 400+ no-code integrations. It suits developers and RPA teams building automated pipelines across global document types at scale. For teams that need extraction plus validation, fraud detection, and transparent per-page pricing in one EU-hosted platform, Koncile is worth evaluating alongside both.
