What LlamaIndex does
LlamaIndex is a developer and enterprise platform for building AI agents over unstructured enterprise content—particularly documents—by turning raw files into “agent-ready” structured data and providing orchestration primitives for retrieval, synthesis, and workflow execution. Its product direction has shifted from being primarily a library for retrieval-augmented generation (RAG) to being a broader “document-to-agents” infrastructure stack that includes agentic document processing (agentic OCR/extraction) and systems for building and running document workflows.
