What does Nuclia do?

Nuclia is a specialized SaaS platform that handles the entire Retrieval-Augmented Generation (RAG) pipeline for you. It automatically processes and indexes your unstructured data—including documents, videos, and audio files—and makes it searchable through AI. You can then query this knowledge base to get generative answers, build AI agents, or integrate AI search capabilities directly into your applications.

The platform stands out by offering modular customization of your RAG pipeline. You can choose different embedding models, define your own chunking and retrieval strategies, and integrate various LLMs. It provides built-in RAG quality metrics (REMi) to evaluate pipeline performance and supports multiple languages. The core technology is powered by NucliaDB, their open-source vector database, which can be deployed in their cloud or your own infrastructure.

This tool primarily benefits developers and organizations building AI-powered applications that need to leverage internal knowledge bases. Real-world use cases include creating intelligent customer support chatbots, building internal knowledge hubs for employees, and adding AI search functionality to existing products. It's particularly valuable for teams that want RAG capabilities without building and maintaining the complex infrastructure themselves.
