Convert your source documents (PDFs, web pages, Word docs, Notion exports) into Markdown with 2markdown, preview them in our Markdown viewer to verify the formatting, then feed them into your RAG pipeline or paste them directly into Claude or ChatGPT. We support standard CommonMark and GitHub Flavored Markdown (GFM) as defaults across all tools. Specific tools support additional extensions — LaTeX math via KaTeX, footnotes, task lists, and tables. The Markdown Viewer renders these in real time so you can verify formatting before exporting.
