What Is Agentic RAG?

Agentic retrieval-augmented generation is the architecture that gives AI agents access to your knowledge base at runtime. Instead of relying solely on what the model was trained on, your agents retrieve relevant documents, chunks, or data from your systems and inject that context into every response. The result: answers that are grounded, sourced, and auditable.

Without RAG, an AI agent only knows what it was trained on. With RAG, it knows your product documentation, your customer history, your internal policies, and can cite exactly where every answer came from. That is the difference between a demo agent and one you trust with your business.

The RAG Pipeline

01

Ingestion

Documents, PDFs, web pages, and database records are parsed, cleaned, and prepared for indexing.

02

Chunking

Content is split into semantically meaningful chunks with overlap, balancing context preservation and retrieval precision.

03

Embedding

Each chunk is converted to a vector embedding via an embedding model. These vectors capture semantic meaning.

04

Retrieval

User queries are embedded and matched against the vector store. Top-k similar chunks are retrieved with similarity scoring.

05

Generation

Retrieved chunks are injected into the LLM prompt as context. The model generates a grounded, sourced response.

Ingestion → Chunking → Embedding → Retrieval → Generation

Five steps from raw documents to sourced, auditable AI responses. Your agents cite your data, not their training set.

Why We Build With RAG

Eliminate Hallucinations

When an agent answers from your documentation, not its training data, the answer is grounded in fact. RAG with source citation makes every response auditable.

Keep Knowledge Current

Update your knowledge base, not the model. New product docs, policy changes, or market data are available to the agent immediately. No retraining required.

Access-Controlled Knowledge

Different agents, different knowledge. A support agent sees help docs. A legal agent sees contracts. RAG with permission scoping means agents only retrieve what they are authorized to see.

Cost-Effective at Scale

Embedding and retrieval are orders of magnitude cheaper than fine-tuning. You can index millions of documents and query them for fractions of a cent per retrieval.

What We Build With RAG

Knowledge Base Agents

Customer support agents that answer from your docs, help center, and internal wiki, with source citations for every answer.

Document Q&A Pipelines

Automated pipelines that ingest contracts, invoices, and case files, then answer natural language queries about their contents.

Real-Time Enrichment

Agents that pull live data from your CRM, database, or API during conversation, enriching responses with current customer context.

When RAG Is the Right Tool

Use RAG When

  • Knowledge changes frequently
  • Responses need source citations
  • Data volume exceeds context window
  • Multiple agents need shared knowledge
  • Access control per document is required

Use Fine-Tuning When

  • You need consistent tone/style
  • The domain is narrow and stable
  • Latency must be minimal
  • Knowledge rarely changes
  • The model IS the product

Consider Alternatives

  • Pure prompt engineering for simple facts
  • Full-text search for keyword matching
  • Graph databases for relationship queries
  • Caching for frequently repeated Q&A
  • Hybrid: RAG + fine-tuning for max accuracy

Frequently Asked Questions

How is RAG different from just using an LLM?
A plain LLM answers only from its training data. It cannot see your documents and it invents details when it does not know. RAG retrieves the relevant chunks from your knowledge base at query time and injects them into the prompt, so the answer comes from your data with a citation you can check.
What data sources can we connect?
We index PDFs, Word documents, wikis, help centers, web pages, CRM records, and SQL databases. If your content lives in a system with an API or an export, we can ingest it into the vector store. Most projects start with the two or three sources that cause the most support load.
How does the system stay current when our docs change?
You update the knowledge base, not the model. We build ingestion pipelines that re-index changed documents on a schedule or on demand through n8n. A new product page or revised policy is searchable within minutes of publishing. No retraining involved.
Can this run self-hosted for data privacy?
Yes. The vector database, embedding service, and LLM can all run on your infrastructure, including on-premises or in your own cloud account. Permission scoping keeps each agent limited to the documents it is authorized to retrieve, and nothing leaves your environment.
What does a typical project cost and how long does it take?
A focused first deployment, one knowledge base, one agent, evaluation set included, usually runs 2 to 4 weeks. Pricing depends on document volume and the number of integrations, so we scope it after a short discovery call. You get a fixed quote before any work starts.
