RAG Development for Intelligent Knowledge Systems

Retrieval-augmented generation lets an AI answer from your documents instead of guessing. The quality depends almost entirely on ingestion, retrieval and evaluation — not the chat window.

The problem

Basic RAG demos split documents into chunks and hope the right one comes back. Answers are confidently wrong when it doesn't.

Permissions, stale documents and missing citations make many knowledge bots unusable inside a company.

The approach

We design ingestion around your document types, combine keyword and vector search, and return answers with sources.

Access control is enforced at retrieval time, and a test set of real questions measures quality before and after each change.

What we build

Internal knowledge assistants
Answer questions from policies, wikis and manuals with citations.
Customer-facing help
Support answers grounded in your product docs.
Document search
Semantic search over contracts, reports or tickets.
Evaluation harness
Repeatable tests that measure retrieval and answer quality.

Use cases

  • Internal policy and HR assistant
  • Product documentation support
  • Sales enablement search
  • Contract lookup

Typical architecture

  1. Document sources

  2. Ingestion + chunking

  3. Embeddings

  4. Vector + keyword index

  5. Retriever with permissions

  6. LLM answer with citations

Technology

  • Python / FastAPI
  • PostgreSQL + pgvector
  • Embedding models
  • LLM APIs or self-hosted models

How we run projects

Questions

RAG or fine-tuning?

RAG for knowledge that changes or needs citations; fine-tuning for style, format or narrow tasks. Many systems use both.

Can it run without sending data to a third party?

Yes, with self-hosted embedding and language models, at some cost to quality and speed.
