Build vs buy is the real question
This is not a feature shootout; it is a build-vs-buy decision. LlamaParse is a serious parsing API -- it handles complex layouts well and slots natively into a LlamaIndex pipeline -- but you adopt it by writing code: an API key, an integration, and a Python environment to run it in. mdstill is the no-build option: you get token-aware GitHub-Flavored Markdown from a browser drop or a single multipart request, with nothing to wire up. If your goal today is a clean .md file rather than a production ingestion system, the no-build path is usually the one you actually want.
