Docling is IBM's open-source document conversion toolkit that transforms PDFs, DOCX, PPTX, and other document formats into structured JSON or markdown. It uses advanced layout analysis and table structure recognition to preserve document structure, making it ideal for preparing documents for RAG and LLM applications. Docling integrates with LlamaIndex and LangChain for seamless pipeline construction.
Unstructured is the leading data ingestion platform for AI applications, transforming unstructured data—PDFs, Word documents, HTML, images, emails—into clean, structured formats ready for LLM consumption and RAG pipelines. The platform handles document parsing, OCR, table extraction, and chunking with high accuracy. Available as open-source and a managed API service, Unstructured is used by enterprises to prepare large document corpora for AI processing.
Frameworks and tools for building retrieval-augmented generation pipelines—document parsing, chunking, indexing, and query engines that connect LLMs to your data.
