# Marker PDF → Markdown

This Space demonstrates the use of [Marker](https://github.com/VikParuchuri/marker), a powerful scientific paper parser developed by Papers with Code, to extract Markdown content from PDF articles.

You can either:
- Upload a `.pdf` file
- Or paste a direct link to a PDF (e.g., from arXiv or OpenAccess journals)

The output is rendered as Markdown and includes the title, abstract, sections, and references if properly parsed.

## How it works

This demo uses the `marker.pdf.process_pdf` Python interface instead of command-line tools, running purely on CPU for maximum compatibility with free-tier Spaces.

The interface is built with Gradio and supports both file uploads and remote URL access.

## Limitations

- Some PDFs with unusual structures (e.g., scanned images or complex layouts) may fail or produce incomplete output.
