Product Overview

What is PageIndex?

PageIndex preview

PageIndex is a document analysis and retrieval framework designed to extract accurate answers from long, complex files without relying on vector databases, embeddings, or arbitrary chunking. By transforming documents into hierarchical tree structures that preserve natural document layout and context, PageIndex enables language models to reason through sections like a human expert reading a table of contents. Available via hosted chat, Python SDK, REST API, and Model Context Protocol (MCP), it provides fully traceable citations and explainable context trails for high-stakes analysis.


Key Features

  • Hierarchical Tree Indexing

    Converts documents into multi-level tree structures that retain natural sections, subsections, and logical context without arbitrary text chunking.

  • Vectorless Reasoning Retrieval

    Replaces approximate vector similarity search with structured model reasoning, navigating document nodes directly to target information.

  • Traceable Page-Level Citations

    Delivers verifiable answers backed by exact page and section references with fully auditable reasoning paths.

  • Developer & MCP Integration

    Integrates into existing agent workflows and development stacks through a Python SDK, REST API, and Model Context Protocol (MCP) server.

  • Enterprise Scale File System

    Extends tree-based reasoning across large-scale document repositories, supporting massive multi-document search and retrieval.


Use Cases

  • Financial Analysis & Due Diligence : Investment teams and analysts can reliably extract metrics, footnotes, and risk factors across dense financial reports and 10-K filings.
  • Legal & Compliance Review : Legal teams can audit complex contracts, regulatory policies, and lengthy compliance bundles with exact source verification.
  • Technical Documentation Navigation : Engineers and product teams can pinpoint specifications, architecture guidelines, and manuals without loss of surrounding context.
  • Enterprise Knowledge Search : Organizations can deploy structured document search across internal files without managing embedding pipelines or vector databases.
  • Scientific & Academic Research : Researchers can query extensive papers, clinical trial data, and literature surveys with evidence-backed citations.
