LlamaIndex

What it is

LlamaIndex became synonymous with retrieval-augmented generation: open-source libraries for ingesting, indexing, and querying private data with LLMs, hundreds of connectors, and agent tooling. LlamaCloud and LlamaParse handle the hardest part — accurately parsing complex PDFs, tables, and forms — as managed services powering enterprise document AI.
