LlamaIndex
A framework and cloud for connecting language models to your documents and data.
About LlamaIndex
LlamaIndex started as a library for retrieval augmented generation and has become one of the most used frameworks for it. It helps you load data from files, databases and apps, break it into pieces, index it and then query it with a language model.
It also offers LlamaParse, a document parsing service that is good at tricky PDFs with tables and charts, and tools for building agents that work over your data. The Python and TypeScript libraries are open source.
LlamaIndex is free to use as a library, while LlamaCloud has a free tier and paid plans. It is a strong pick for teams whose main problem is getting good answers out of messy documents.
