It turns documents into tree-like hierarchical indexes that mimic how human experts read and extract information, then uses large language models for reasoning retrieval. [Core features] Structured index: convert PDFs into directory-like trees that keep full document hierarchy. Reasoning retrieval: tree search for context-aware extraction without vector similarity matching. Traceability: clear page and section citations with transparent, explainable retrieval. Zero infra: no vector DB, chunking, or embedding pipeline. On the FinanceBench financial-document analysis benchmark it reaches 98.7% accuracy—suited to financial reports, legal docs, technical manuals, and other long professional documents.
