RAG Systems
Answers grounded in your documents, with the source cited.
Retrieval-augmented generation lets a language model answer from your own content instead of its training data. We treat retrieval quality as the product, because that is what separates a system people trust from a demo that hallucinates confidently.
Tools we work in
- LangChain
- LlamaIndex
- pgvector
- Pinecone
- Qdrant
- Cohere Rerank
- OpenAI
- Postgres

Scope
What this covers
The specific work included when you engage us for this service.
- Chunking strategy designed around your documents, not a default setting
- Hybrid search combining vector similarity with keyword and metadata filters
- Reranking to lift the right passage into the model's context window
- Source citation so every answer points at the passage it came from
- Access control so users only retrieve documents they are allowed to see
- Evaluation harness measuring retrieval hit rate and answer accuracy over time
What you receive
- 01A working retrieval pipeline connected to your document sources
- 02An evaluation report with a baseline you can measure future changes against
- 03A document ingestion process that keeps the index current as content changes
Questions
RAG Systems, answered
Why do so many RAG projects disappoint?
Because the team optimised the prompt and ignored the retrieval. If the right passage never reaches the model, no amount of prompt engineering fixes the answer. We instrument retrieval hit rate first, and only tune the generation step once retrieval is provably working.
Can this run on our own infrastructure with sensitive documents?
Yes. Open-weight models can be served locally, the vector store can live inside your network, and no document content leaves your environment. That configuration is the standard choice for healthcare and legal work rather than an exotic option.
