What is LlamaIndex?

LlamaIndex is an applied AI lab that builds models for document parsing and extraction. Its main commercial platform, LlamaParse, parses (Parse) more than 50 types of unstructured files, performs schema-based structured extraction (Extract), and offers splitting (Split), classification (Classify), and indexing (Index). It also turns handwriting, tables, and charts into structured data and catches errors with an automatic correction loop. Its open-source offerings are the LlamaIndex framework for building RAG and agent apps (300+ integration packages) and LiteParse, which parses documents locally without the cloud or LLM tokens. According to the GitHub notice, the company's main focus has shifted from the open-source framework to LlamaParse.
