What is Papermill used for?
Papermill helps developers convert unstructured documents (PDFs, images) into clean Markdown and structured assets for AI training, RAG, and automated analysis.
RAG-Ready Document Extraction
Unstructured Documents to
Clean, AI-Ready Markdown.
Papermill transforms complex PDFs into structured Markdown and assets—and lets you chat with your documents. Upload files or provide URLs, then ask questions with full context awareness.

PDFs are data silos.
Your AI should not have to guess.
Structured Extraction is Hard
Extracting tables, headers, and images from PDFs usually results in garbled text. Papermill maintains semantic integrity and layout hierarchy even in complex documents.
Disconnected Assets Break RAG
Lost figures and broken table references make retrieval brittle. Papermill provides deterministic linkages between text chunks and extracted images, ensuring your LLM has full context.
