The web's entities — extracted, connected, and searchable
Search engines index pages. MassIndex indexes the things those pages describe — companies, people, products, and places. Structured, linked together in a knowledge graph, and always current.
Search entities, not just web pages
MassIndex extracts structured data from across the web and organizes it into searchable collections — each linked to related entities in the knowledge graph.
