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

Our proprietary AI reasoning engine precisely navigates through and analyzes the intricacies of the millions of lines of code within your applications. Developers can instantly pinpoint their desired code. You need to understand every business process, piece of data, or decision point embedded in your code before you can confidently manage, change, or integrate the COBOL applications at the core of the enterprise. Colleague transforms your code into a valuable knowledge base with our logic-based reasoning engine. Unlike generative AI, our technology is precise and explainable. Explore and compare different scenarios by changing conditions in real-time without getting lost.
