PageIndex: Open-source document indexing for reasoning-based RAG without vector embeddings

VectifyAI has released PageIndex, an open-source Python library that implements a 'vectorless' approach to retrieval-augmented generation, relying on reasoning-based document indexing rather than traditional vector embeddings. The project has accumulated 34,534 GitHub stars with 222 added today, indicating strong community traction. The approach challenges the dominant vector-store paradigm for RAG pipelines.
