AI teams building retrieval-augmented generation pipelines use this recipe to convert source documents into clean markdown that chunks well and produces high-quality embeddings.

APIs Used

Document to Markdown (1 credit per page)

Prerequisites

You need an Iteration Layer API key. Get one at platform.iterationlayer.com — free trial credits included, no credit card required.
