PDF to Markdown

This example walks a directory of local PDF files, converts each one to Markdown using docling, and writes the resulting .md files to an output folder.

Prerequisites

• Python 3.11+
• No external services required — all processing runs locally on CPU.

Run

Install deps:

pip install -e .

Place the PDF files you want to convert in a pdf_files/ directory (a sample PDF — the "Attention Is All You Need" paper — is already included).

Build/update the index (converts PDFs and writes Markdown to out/):

cocoindex update main

The converted .md files will appear in ./out/, with each file named after the original PDF (e.g. 1706.03762v7.md).
