Overview
PageIndex replaces vector databases with hierarchical tree indexes for documents and uses LLM reasoning to search through them. It provides traceable, explainable retrieval without chunking or vector similarity search. The system includes an SDK for local or cloud use and is designed for long, complex professional documents.
Deep Analysis
Key Differentiator
Replaces vector similarity search with LLM reasoning over hierarchical tree indexes for context-aware document retrieval.
⚡ Capabilities
- • tree-structure index generation
- • LLM reasoning-based retrieval
- • local and cloud deployment
- • traceable reference retrieval
