PageIndex
A vectorless RAG system that uses reasoning instead of embeddings to retrieve document chunks.
The hype outruns what you'd actually get.
Teams already using LLMs for document search and willing to debug complex reasoning pipelines.
Paid RAG tools like Pinecone or Weaviate, or manual prompt engineering with PDFs.
Highly experimental, no production docs, 143 open issues, and no clear path to stable performance.
Run the example script on a single PDF and measure if it answers a simple question correctly.
