Processes PDF and Markdown documents into recursive JSON tree structures where each node represents a document section with extracted title, page range, and LLM-generated summary. The indexing pipeline uses table-of-contents extraction and semantic section detection to build a hierarchical representation without requiring vector embeddings or manual chunking, enabling natural document structure preservation.
Unique: Uses hierarchical tree indexing modeled on table-of-contents structure instead of flat vector embeddings, with LLM-generated summaries at each node enabling reasoning-based navigation rather than similarity-based retrieval. Eliminates chunking entirely by respecting natural document boundaries.
vs alternatives: Achieves 98.7% accuracy on FinanceBench vs traditional vector RAG because it treats retrieval as a reasoning problem over structured hierarchy rather than approximate similarity matching, making it superior for documents requiring domain expertise and multi-step reasoning.
Implements a retrieval phase where LLMs navigate the hierarchical tree index using a search prompt to reason about which sections are relevant, selecting nodes by node_id and fetching full text for answer generation. The system uses the tree structure as a reasoning scaffold, allowing the LLM to traverse from high-level summaries to specific sections without vector similarity approximation.
Unique: Uses LLM reasoning over tree structure as the primary retrieval mechanism rather than vector similarity, with the tree hierarchy serving as a reasoning scaffold that guides the LLM through document sections. Supports multiple search strategies (tree-based, metadata-based, semantic, description-based) all operating on the same hierarchical index.
vs alternatives: Outperforms vector RAG on domain-specific documents because LLM reasoning can understand complex relevance criteria that vector similarity cannot capture, while maintaining full explainability through section titles and page references.
Provides a flexible configuration system that allows users to specify LLM model selection (OpenAI, Anthropic, Ollama), temperature and sampling parameters, indexing strategies, and retrieval behavior. Configuration can be set via environment variables, config files, or programmatic API, enabling customization without code changes.
Unique: Provides centralized configuration management for LLM selection, sampling parameters, and indexing behavior, enabling experimentation with different models and settings without code changes. Supports multiple configuration sources (files, environment, programmatic API).
vs alternatives: More flexible than hardcoded LLM selection because configuration allows runtime switching between providers and parameter tuning, whereas many RAG systems require code changes or separate deployments for different configurations.
Provides a comprehensive CLI tool (run_pageindex.py) that exposes indexing and retrieval operations without requiring Python programming. The CLI supports document upload, index generation, query execution, and result formatting, enabling non-technical users and shell scripts to interact with PageIndex functionality.
Unique: Provides a complete CLI interface that exposes PageIndex indexing and retrieval without requiring Python programming, enabling shell script integration and non-technical user access. Supports multiple output formats for different consumption patterns.
vs alternatives: More accessible than API-only systems because CLI enables shell integration and quick prototyping without application development, though with less flexibility than programmatic interfaces for complex workflows.
Implements a relevance scoring mechanism where the LLM reasons about section relevance based on content understanding rather than statistical similarity. The system generates explicit reasoning traces showing why sections were selected, enabling users to understand and verify retrieval decisions. Scores reflect semantic relevance determined through LLM reasoning rather than embedding distance.
Unique: Generates explicit reasoning traces for section selection rather than opaque similarity scores, enabling users to understand and verify retrieval decisions. Treats relevance as a reasoning problem with transparent justification rather than a black-box similarity metric.
vs alternatives: More interpretable than vector RAG because reasoning traces explain why sections were selected based on content understanding, whereas vector similarity provides only distance metrics that don't explain relevance to users.
Provides four distinct retrieval strategies operating on the same hierarchical index: tree-based search (LLM navigates hierarchy), metadata search (filters by page range or section title), semantic search (uses descriptions to find relevant sections), and description-based search (matches against LLM-generated summaries). Each strategy can be composed or used independently depending on query type and document characteristics.
Unique: Implements four orthogonal search strategies (tree-based, metadata, semantic, description) all operating on the same hierarchical index, allowing composition and fallback mechanisms. Unlike vector-only systems, it provides explicit control over retrieval strategy and can combine multiple approaches for improved recall.
vs alternatives: More flexible than single-strategy vector RAG because it supports metadata and description-based search without requiring separate indices, and allows explicit strategy composition rather than relying solely on embedding similarity.
Extends the indexing pipeline to process documents containing images, diagrams, and visual elements by using vision LLMs to extract text and semantic content from images. The extracted visual content is integrated into the tree structure alongside text-based sections, enabling comprehensive indexing of documents with mixed media content.
Unique: Integrates vision LLM processing into the indexing pipeline to extract semantic content from images and diagrams, treating visual elements as first-class nodes in the hierarchical tree rather than discarding them. Enables unified retrieval across text and visual content.
vs alternatives: Handles multimodal documents more comprehensively than text-only RAG systems by extracting visual semantics and integrating them into the searchable index, rather than requiring separate image search or manual annotation.
Provides native integration with OpenAI Agents SDK and other agentic frameworks, exposing PageIndex retrieval as a callable tool that agents can invoke during reasoning loops. The integration enables agents to autonomously decide when to retrieve document sections, compose multi-step queries, and iteratively refine retrieval based on intermediate results.
Unique: Exposes PageIndex retrieval as a first-class tool in agentic frameworks, allowing agents to autonomously invoke retrieval during reasoning loops rather than requiring manual orchestration. Supports iterative refinement where agents can compose multi-step queries based on intermediate results.
vs alternatives: Enables more sophisticated agentic workflows than static RAG because agents can reason about what to retrieve and iterate based on results, rather than executing a single retrieval step before answer generation.

Automatically generates vector embeddings for Strapi content entries using configurable AI providers (OpenAI, Anthropic, or local models). Hooks into Strapi's lifecycle events to trigger embedding generation on content creation/update, storing dense vectors in PostgreSQL via pgvector extension. Supports batch processing and selective field embedding based on content type configuration.

Unique: Automatically tracks embedding provenance (model, provider, timestamp) alongside vectors, enabling version-aware search and stale embedding detection without manual configuration
vs alternatives: Provides built-in audit trail for embeddings, whereas most vector databases treat embeddings as opaque and unversioned
