LlamaIndex

LlamaIndex is a data framework that connects LLMs to your documents for retrieval-augmented generation (RAG) and AI agents, starting with a free document processing tier. It includes LlamaParse, an industry-leading document processing tool that uses agentic OCR, structured extraction with defined schemas, and auto-correction loops to handle complex layouts, handwritten text, tables, and charts. The platform processes over 1 billion documents and has 25 million+ monthly package downloads. It offers a free plan with 10,000 credits per month (~1000 pages). Paid plans are available for higher volume. LlamaIndex suits developers and solopreneurs building document-heavy AI workflows, such as financial due diligence, invoice processing, technical document search, and customer support automation.
