Markdown Document Processing With Heading Based Hierarchy Extraction

via “document structure parsing and layout analysis via pp-structurev3”

Turn any PDF or image document into structured data for your AI. A powerful, lightweight OCR toolkit that bridges the gap between images/PDFs and LLMs. Supports 100+ languages.

Unique: Hierarchical detection-recognition architecture that identifies structural elements (tables, text blocks, figures) separately from raw text, enabling semantic-aware document decomposition. Uses PaddlePaddle's graph optimization to parallelize detection and recognition stages, reducing latency vs sequential pipelines. Outputs both Markdown (human-readable) and JSON (machine-parseable) simultaneously.
