About PageIndex

PageIndex is an AI tool designed to assist users in reading and analyzing complex documents such as reports, filings, research papers, and technical manuals.

The tool supports ultra-long context, enabling reasoning across thousands of pages without losing precision. It natively understands text, tables, figures, charts, and images within documents, and offers cross-document analysis to uncover patterns and insights that single-file tools may miss. Users can upload their own documents, share folders via links, and follow live knowledge libraries that stay updated. The platform is structured as a workspace where teams or individuals can collaborate and access shared knowledge resources.
