Fast, reliable
document to Markdown

LLMs read Markdown more reliably than PDF, HTML, or raw text. The structure — headings, lists, tables, code fences — is explicit rather than implied by layout, so the model sees the same document you do. That lifts retrieval accuracy in RAG and reduces the kind of hallucinated “I can’t find that section” answer you get when you dump a PDF directly into a prompt.

Markdown is also dense: a typical DOCX or PDF loses 30–60% of its token count once stripped of XML and style junk. Fewer tokens mean cheaper API calls, more context budget for your actual instructions, and faster responses. For RAG specifically, heading boundaries give a natural place to cut chunks that don't shred tables in half.

For developer workflows the story is similar: Markdown diffs cleanly in git, renders in every code host and editor, and imports straight into Obsidian, Notion, and static site generators. One conversion, consumable everywhere.

mdstill does this conversion with a layered pipeline of battle-tested parsers and layout-aware extractors — not a brittle custom regex stack nobody audits. Files touch a stateless worker for about a second, then disappear.
