Why Markdown for AI and RAG pipelines
Language models read structure, not layout. A PDF's columns, headers and footers become noise once the text is flattened, and a chatbot grounded on that text answers from fragments. Markdown keeps the heading hierarchy, lists and tables that let a retrieval system chunk a document along its real boundaries — so an answer cites the right section instead of the paragraph next to it.
These converters do that one step. If you would rather skip it entirely, CustomerGPT ingests your site, help centre and documents directly and keeps them in sync — see how it works or the integrations.
Turn those documents into a support agent that answers from them
Point CustomerGPT at your website and docs and it deploys a grounded AI support agent that cites its sources.
