MinerU

OpenDataLab document parser that turns PDF, DOCX, PPTX, XLSX, and images into clean, LLM-ready markdown and JSON with strong OCR, the fix for garbage RAG inputs. Fine print: it moved off AGPLv3 to a custom 'MinerU Open Source License' (Apache-2.0 based, with added commercial and attribution conditions), so read the terms before a commercial build.

Vet the fine print a star count hides: real license and a gate on dual-use tools

Before you build on a starred repo, record its actual license (not an assumed permissive one) and whether it is dual-use, so a custom license or an impersonation risk never surprises you after you have shipped.
