This approach provides exact page references and explainable retrieval decisions, making it highly accurate for domain-specific documents without needing vector databases or chunking.

PageIndex achieves 98.7% accuracy on the FinanceBench benchmark, which tests RAG systems on complex financial document analysis tasks. This is noted as the highest accuracy in the market for such benchmarks.
