LlamaIndex

LlamaIndex is a document processing platform that parses, extracts, and indexes documents for AI applications.

LlamaIndex is a document processing platform that provides hosted APIs to get data out of documents for AI applications. It converts PDFs, scans, and Office files to clean markdown, text, or JSON through agentic OCR, pulls typed schema-shaped data with citations, and manages ingestion, embedding, and retrieval for RAG. It also classifies documents by type and splits combined files into logical sections. Developers can use SDKs for Python, TypeScript, Go, and Java to chain these capabilities or use them individually. The platform operates on credit-based pricing billed per page or minute.
