NucliaDB, the RAG database.

NucliaDB, the #1 RAG Database

NucliaDB is the open-source database behind Nuclia, and it is the first and only database designed specifically for Retrieval-Augmented Generation.

The Problem with Conventional Vector Databases

Vector databases are great at semantic similarity—but RAG requires more than “close enough.” True AI-powered knowledge systems demand context, relationships, traceability, and flexibility across formats. And that’s where other databases fall short.

They lack:

– Contextual linking between pieces of data
– No support for rich metadata and assets
– No understanding of relationships or hierarchies
– Limited to semantic proximity, not real-world meaning

Why NucliaDB Changes Everything

NucliaDB doesn’t just store vectors. It builds a living knowledge network—connecting unstructured data, structured content, and everything in between. It doesn’t return “matches”—it delivers answers. Actionable. Verifiable. Context-rich.

NucliaDB unifies:

✅ Semantic search
✅ Keyword search
✅ Metadata search
✅ Knowledge graph traversal
✅ Multi-modal understanding

Whether you’re indexing 10 files or 10 million, NucliaDB gives your AI the superpowers it needs to produce coherent, trusted, human-grade answers.

What Makes NucliaDB Different?

How can Nuclia and NucliaDB support your product build?

Built for Every Data Type

Text, PDFs, videos, audio, structured or unstructured—NucliaDB speaks them all. Ask a question across formats and NucliaDB will bring back a unified, meaningful response.

+30 Retrieval Strategies

Go beyond semantic search. Use:

• Vector indexing for conceptual links
• Full-text search for precision
• Knowledge graphs to map relationships
• Metadata & asset filters to zoom in on specifics

Trace Every Answer

Trust your AI with built-in traceability. NucliaDB points directly to the original source—down to the video timestamp or slide number.

Context-Aware for Better AI

LLMs need context to perform. NucliaDB provides it—transforming fragmented data into coherent stories that improve generation accuracy and reduce hallucinations.

Real-World Use Cases

🔹 Enterprise Chatbots with Depth
Don’t settle for generic answers. NucliaDB-powered bots reference original documents, pull quotes from videos, and enrich replies with real context.

🔹 Team Knowledge Management
Turn scattered files into a searchable knowledge base. Find policies in slides, quotes in transcripts, or specs in product manuals—instantly.

🔹 Search Across Multimedia
Why limit to text? Index and retrieve insights from audio, video, and image content—just like you would with text.

It’s Not Just Search. It’s Understanding.

In a world where data is fragmented and growing exponentially, NucliaDB is your edge. It empowers your AI with contextual retrieval, multi-modal reasoning, and trusted traceability.
