Why developers switch from PDF.ai
PDF.ai Parse is a strong PDF parser. Iteration Layer is broader document-to-markdown conversion.
Broader input formats
Convert more than PDFs: Office documents, emails, EPUB, RTF, LaTeX, images, and other common formats use the same endpoint.
Image files become useful markdown context
Image inputs include OCR text and a natural language description for downstream LLM and RAG workflows.
Same account as the rest of your content APIs
Use document-to-markdown alongside extraction, generation, sheets, website extraction, and image APIs with one credit pool.
