Frequently asked questions
Is Markdown better than plain text for LLM processing?+
Yes — Markdown preserves structure (headings, lists, tables) that helps the LLM understand the document hierarchy and retrieve relevant sections.
How should I chunk the Markdown for a RAG pipeline?+
Split by H2 or H3 heading level for section-level chunks. Use a token-aware chunker (e.g., LangChain's MarkdownTextSplitter) to stay within context window limits.
Should I clean the Markdown before feeding to the LLM?+
Yes — remove running headers, page numbers, and footnotes that add noise without semantic value to the LLM context.
