About

PageIndex is a human-like document AI platform for understanding long, complex documents with precise, verifiable answers grounded directly in the source. It uses vectorless, reasoning-based retrieval instead of embeddings, chunking, or vector databases, transforming each document into a tree-structured index that mirrors how people navigate sections, subsections, pages, and content. An LLM then reasons over that structure to decide where to look for relevant information, producing context-aware retrieval that is traceable and explainable. Users can upload reports, filings, research papers, technical manuals, legal documents, medical files, textbooks, and business plans, then ask questions with line-level citations that can be reviewed and verified. PageIndex supports ultra-long documents spanning thousands of pages and understands text, tables, charts, figures, and images.

About

Combine semantic relevance and user feedback to reliably retrieve the optimal document chunks in your retrieval augmented generation system. Combine semantic relevance and document freshness in your search system, because more recent results tend to be more accurate. Build a real-time personalized ecommerce product feed with user vectors constructed from SKU embeddings the user interacted with. Discover behavioral clusters of your customers using a vector index in your data warehouse. Describe and load your data, use spaces to construct your indices and run queries - all in-memory within a Python notebook.
