LLM integration and RAG
on your own systems and documents.
We connect GPT, Claude, Gemini or open models to the software you already run, and make them answer from your documents with citations. Access rules, data residency and retrieval quality are designed in from the start.
Your knowledge, made searchable by a model.
Most organisations already hold the answers their staff and customers need. They sit in policies, contracts, tickets, wikis and shared drives that nobody can search well. Retrieval-augmented generation fixes that. The model reads the relevant passages first, then answers and shows where each claim came from.
The hard part is not calling an API. It is splitting documents sensibly, finding the right passage for a vague question, respecting who may see what, and proving the answers are correct. We build that layer, test retrieval on real questions from your team, and plug the result into the systems people already use.

From a single API call to a full retrieval platform.
We start with the documents and questions that matter most, measure retrieval quality on them, and widen the scope once the numbers hold up.
LLM integration into existing systems.
Model calls added to your CRM, ERP, help desk or internal tools through clean APIs. Classification, extraction and drafting inside the screens your team already uses, with timeouts, retries and fallbacks so an outage at the provider does not break your product.
RAG over your own documents.
Question answering grounded in your files. We ingest PDFs, Word documents, SharePoint, Confluence and databases, keep the index in sync as documents change, and return answers with links to the exact source passage.
Chunking, embeddings and hybrid search.
Retrieval tuned to how your documents are written. Structure-aware chunking, embedding model selection, keyword plus vector search, and re-ranking, chosen by testing against your own question set.
Document-level access control.
Users only get answers from documents they are allowed to open. Permissions from your identity provider or source system travel with every chunk and are enforced at query time, not filtered after the fact.
Model selection and routing.
The right model for each request. Simple lookups go to fast, low-cost models and harder reasoning goes to stronger ones, behind one internal interface so you can swap providers without rewriting the application.
Private deployment and retrieval evals.
Models hosted where your data rules require. Azure OpenAI, AWS Bedrock, Vertex AI in UK or EU regions, or open models on your own infrastructure, with evaluation suites that track retrieval accuracy and answer faithfulness over time.

Yes. We can use Azure OpenAI, AWS Bedrock or Vertex AI in a UK or EU region under your own cloud account, or run an open model such as Llama or Mistral on your infrastructure. The vector store can sit in your own database too. Self-hosted models need more engineering and may answer less well on hard questions, so we test both options on your data before you decide.
The build cost is driven by the number and messiness of your sources, how strict access control needs to be, and where the model has to be hosted. A single well-structured document set behind one interface is a modest project. Many sources with mixed permissions and private hosting is a larger one. Running costs depend on query volume and model choice, and we estimate them before build starts.
We instruct the model to answer only from retrieved passages, show citations for every answer, and say so when the documents do not cover the question. We then score answers for faithfulness against a test set built from your real questions. This cuts errors sharply, but no RAG system is perfect, so citations let users check anything important.
There is no single best model. We shortlist a few based on your hosting rules, budget and language needs, then compare them on your own questions. The integration layer is provider-neutral, so changing model later is a configuration change rather than a rebuild.
Yes, if the permissions exist in the source system. We carry access rules from SharePoint, Google Drive, your identity provider or your database into the index and filter at query time. Where source permissions are inconsistent, we flag it during discovery, because RAG will expose any gaps that already exist.
For answering questions from changing documents, RAG is usually the right tool because the index updates without retraining. Fine-tuning helps when you need a consistent format, tone or specialist vocabulary. Some projects use both, but we start with RAG and only fine-tune if testing shows a clear gap.
