Precision document parsing and data extraction for enterprise workflows
Reads tables, forms, charts and multi-column layouts while preserving reading order and relationships between elements.
Handles PDF, PPT, Word, images and web pages — including scanned and low-quality documents.
Self-hosted and on-premise deployment plus PII masking so sensitive data can be kept out of third-party models.
Returns Markdown, JSON, CSV or key-value output that plugs directly into RAG and data pipelines.
