Document AI & OCR

Built on our open-source work in Vietnamese OCR and document layout analysis, we digitize documents end-to-end: detect layout, read Vietnamese text accurately, and extract key fields from financial statements, invoices, and forms into clean structured data.

SAMPLE

Press Run OCR to see the recognised text.

Simulated with sample documents (organisations, IDs and signatures are placeholders). The structured extraction is computed directly from the recognised lines. The real pipeline runs YOLOv7 layout analysis + VietOCR recognition.
