PDF To Markdown Multisource · camilomartinezm bundle Convert scientific, academic, scanned, two-column, and math-heavy PDFs into provenance-rich Markdown with CUDA Docling, PyMuPDF4LLM, native geometry, GROBID, MinerU, span-preserving PP-StructureV3 region rescue, and benchmark-gated VLM evidence. Use when extraction quality matters, especially for interleaved columns, glued words, headers/footers, watermark fragments, broken section order, empty grids, missing sections, or corrupt equations, tables, figures, and captions. Treat every automated output as a quality-gated draft that requires direct native-PDF inspection and manual Markdown postprocessing before final use.
