Could you build this?
Partial A standard RAG chat app with citations is simple to vibe-code, but PageIndex's vectorless, hierarchical tree-indexing reasoning engine that parses complex enterprise documents with exact line-level grounding requires novel information retrieval algorithms.
What it would actually take: Requires a custom document parsing engine that converts dense PDFs, financial tables, and reports into hierarchical semantic trees rather than flat text chunks. The core IP is the vectorless tree-search and reasoning retrieval algorithm that navigates document structure via LLM reasoning passes while preserving exact bounding box/line coordinates for citation verification. Requires advanced knowledge in document understanding, AST-like layout representations, and retrieval algorithms beyond off-the-shelf vector embeddings.
