A small Python library that parses PDF files into Markdown using a vision-capable LLM such as GPT-4o. It uses PyMuPDF to detect non-text areas and sends them to a multimodal model to handle formulas, tables, charts, and images.

Use cases

• convert pdf to markdown
• extract math formulas from pdf
• parse tables and charts from pdf documents
• ocr pdf with gpt-4o
• convert research papers to markdown
• extract images from pdf while converting text

When to choose

• you need high-fidelity PDF-to-Markdown conversion including formulas, tables, and charts
• you have access to an OpenAI-compatible vision model API and per-page cost (~$0.013) is acceptable
• you want a simple, minimal Python API (parse_pdf) rather than a heavy pipeline

When to avoid

• you need fully offline or free parsing with no LLM API costs
• you must process large volumes of PDFs where per-page API charges are prohibitive
• you need pixel-perfect layout reproduction rather than Markdown output
