Description

Nuclia automates AI-powered indexing and retrieval of unstructured data—documents, videos, audio, images to deliver trusted, generative answers. Its modular RAG-as-a-Service platform lets you customize pipelines (chunking, embeddings, LLMs), include quality metrics, and deploy on cloud or on-premise, ensuring full governance. An organization can unlock value and insights instantly to deploy scalable AI agents, customize retrieval and chunking strategies, and evaluate performance with advanced metrics. Unique features include continuous model adapters, multi-model generative selection (Gemini, Claude, Mistral, private models), and synthetic QA generation.

Built with privacy and governance at its core, Nuclia stands out for its open-source AI search database and zero lock-in, giving IT teams full control over data deployment. Leading brands trust Nuclia for its flexibility and strong security, making it ideal for enterprises needing powerful generative search and knowledge workflows.

Nuclia stands out by offering agentic RAG—a full-stack solution rather than just embeddings or search. It is trusted by brands like Columbia Business School and Banco Mediolanum.

Nuclia Free Plan

Nuclia does not offer a free plan. You can explore its Fly paid plans using a 14-day free trial.

The free trial allows indexing of unstructured data, testing semantic search, generative Q&A, and LLM switching. It lets users explore features but is limited in data volume and lacks long‑term analytics and SLA support. Paid plan required for production use, larger stores, and enterprise support.
