Nuclia is a RAG-as-a-Service / AI search platform (now part of Progress as Progress Agentic RAG). It ingests unstructured data - documents, files, audio, video, web pages and conversations - into Knowledge Boxes, automatically extracting, embedding and indexing it so applications can run hybrid (semantic, keyword, graph) search and get grounded generative answers through a regional REST API.
