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.
