About Pageindex Expand
PageIndex offers a specialized approach to document understanding, delivering precise and verifiable answers from complex documents. It targets developers and enterprises who need explainable insights without relying on vector databases.
This product uses a reasoning-based RAG (Retrieval Augmented Generation) method, which differentiates it from traditional vector similarity search.
