Document AI company Lomin won the Top Innovation Award at NH NongHyup Bank’s “2025 NH Open Business Day.”

The recognition follows a demonstration of Lomin’s vision-language model (VLM)-based Document AI platform, “Textscope Supernova,” which improved recognition performance compared to conventional AI optical character recognition (OCR) and showcased a method for extracting document data using prompt-based configuration and training with small data volumes.

Lomin conducted a Document AI proof-of-concept on unstructured financial forms used by NH NongHyup Bank, including operational instruction sheets and local income tax special collection payment forms. Under the same conditions, Lomin benchmarked Supernova against an existing AI OCR solution on the same document templates.

Results showed that Supernova reduced the recognition error rate by approximately 58% versus the existing AI OCR solution and improved per-document processing speed by approximately 21%. For a single document type, Supernova demonstrated superior performance in reading quality and processing speed.

Building on the PoC, Lomin and NH NongHyup Bank are reviewing plans to expand Supernova’s application to additional document domains—such as loan-related documents and audit and risk management documentation—and to consider rollout across other NongHyup affiliates, including NH NongHyup Life Insurance, NH NongHyup Property & Casualty Insurance, and NH NongHyup Asset Management.

“Through this PoC with NH NongHyup Bank, we validated—using concrete metrics—the outcomes VLM-based Document AI can deliver in the financial document domain,” said Ji-hong Kang, CEO of Lomin. “We will continue to grow Zixy into a standard Document AI platform across industries that require document workflow innovation, including finance as well as manufacturing and the public sector.”

Zixy is Lomin’s service brand that adds features such as document classification model training and administrator capabilities on top of Supernova and is delivered as software-as-a-service (SaaS). The official launch is scheduled for the first quarter of next year.
