## The Hook

LlamaIndex connects LLMs to data sources that are not just documents.

## What's Good

The connector ecosystem is unmatched: 160+ data loaders handle everything from Notion to Snowflake. The indexing abstractions (vector, keyword, knowledge graph) let you pick the right retrieval strategy for your data shape.

## The Catch

The abstraction layers can be confusing. Index, query engine, retriever, synthesizer—the terminology requires investment to master.

## Verdict

The best data plumbing for LLM applications.
