Highest Level of Accuracy for Korean Characters

Providing higher recognition accuracy of 99.3% compared to third party solutions with accumulative high-quality training data through years of digital document processing expertise

Easy-to-use Form Template Tools

Usability is enhanced by providing template-based form recognition, classification and results in Key Value Pair (KVP) format. A provided template guide and examples make it easy for anyone to use


Deep Learning Form Template with Document Understanding

Easily extract, learn, and operate data insights from unstructured forms with Key Value Trainer, a GUI-based learning/operation tool

Flexibility and Scalability

SDK (C ++, Java) and REST API provide flexibly expanded and applicable to other systems.




Extracting Key Values from Unstructured Forms

Provides GUI-based learning and operation tools for learning, inspecting, distributing, and operating unstructured format images

Detecting Table and Extract Data

Detecting table and provide table information. Table information includes table position, row/column size and merge information, cell size, and text in each cell.

Detection / Recognition of Checkbox

Recognize checkboxes contained in various document forms, such as consent forms and applications.

Recognize Large Size Image

Provides high accuracy for large size images without any extra task like a split-and-merge. (ex, product image in online shop)

Conversion and Merge to PDF

Searchable PDF files can be useful for digital document archiving. And number of images and PDF files can be merged into a single readable PDF.

De-identification of Sensitive Data

Provides de-identification of various formats such as resident registration number and passport number through regular expression.




Forms can be classified in fields such as finance, manufacturing, public, and IT and necessary data can be extracted. The extracted data may be applied to the RPA(Robotic process automation) software.


Detects and de-identification of sensitive information such as personal information in the image. The extracted data may be applied to the DLP(Data Loss Prevention) software.


It is used to build or analyze big data by recognizing real-scene images used in business environments and daily life.




It is used to extracting data from transmitted and received fax images.
