No it's all rules-based. I think the code you're referring to is "extractors", which are website-specific rules that I'm working on to standardize the output from sites with comments threads (e.g. HN, Reddit) and conversational chats (ChatGPT, Claude, Gemini).

I would love something which reliably extracted a markdown back/forth from all the main LLM providers. I tried `defuddle` on a shared Gemini URL and it returned nothing but the "Sign In" link. Maybe I'm using your extractor wrong? How are you managing to get the rendered conversation HTML?
