What problem does it solve? Documents in formats like PDF, Word, PowerPoint, and Excel are difficult for LLMs and text pipelines to consume directly. This Skill converts them into clean, token-efficient Markdown so content can be analyzed, indexed, or fed into AI workflows. ## Core Features & Use Cases - Multi-Format Conversion: Convert PDF, DOCX, PPTX, XLSX, HTML, CSV, JSON, XML, ZIP, EPUB, images (with OCR), audio (with transcription), and YouTube URLs to Markdown. - AI-Enhanced Image Descriptions: Use vision models via OpenRouter to generate detailed descriptions of figures and slides during conversion. - Batch and Literature Workflows: Included scripts batch-convert directories in parallel and convert scientific paper collections with metadata extraction and index generation. - Use Case: Convert a folder of research paper PDFs into Markdown files with YAML front matter, organized by year, plus an INDEX.md catalog for a literature review. ## Quick Start Convert the attached document 'paper.pdf' to Markdown and save the result as paper.md.
