In my last post about building the PDF to Markdown converter , I listed some “what’s next” ideas at the end. One of them was:

You know that feeling when you download a brilliant research paper, only to realize you can’t easily feed it into your AI workflow? Or when you want to add documentation to your knowledge base, but it’s locked in a format that doesn’t play well with version control or LLM tools?
