RAG Chatbots & Knowledge Assistants · UK-Based
RAG chatbots that pass a compliance audit
Chunk-and-embed retrieval is fine for a demo and dangerous in a regulated setting. RAG is the retrieval brain behind a chatbot or voice agent, and we build it for document-heavy and regulated sectors: citation-traceable, data-resident, access-controlled, and gated by an evaluation harness. On AWS, by ex-AWS engineers.

Standard RAG chatbots fail where it matters most
A regulated knowledge assistant is judged not on whether it usually answers well, but on whether every answer it gives a user can be traced, defended, and reproduced.
It cannot prove where an answer came from
Concatenating chunks into a prompt produces an amalgam. Ask which source justifies what the chatbot told a customer and the honest answer is often unclear, disqualifying when the conversation informs a real decision.
It ignores residency and access control
A flat vector store treats every document as equally retrievable by everyone. But access is governed by role, jurisdiction, and residency law. A chatbot that surfaces a passage a user was never entitled to see isn't a bug. It's a breach.
It has no notion of correctness
Naive pipelines have no evaluation. They can't tell you whether an index update or an embedding swap made the assistant's answers better or worse. 'We think it's fine' is not an answer you can give a regulator.
We build the retrieval brain behind your chatbot or voice agent to answer the harder questions: where did this come from, was the data allowed to be here, and is the whole system measurably correct?
The four properties of audit-ready RAG chatbots
Designed into the retrieval layer behind your chatbot or voice agent from the outset on AWS-native infrastructure, not bolted on before a review.
Citation traceability
Every answer the chatbot gives maps to a specific, retrievable source span, not just a document. Reviewers click straight through to the exact passage behind a reply and verify in seconds.
Data residency & access control
Storage, embedding, and inference pinned to specific AWS regions, with the conversing user's entitlements enforced as a hard filter before the model ever sees a passage.
Multi-hop retrieval
Query decomposition, structured retrieval that follows document relationships, and re-ranking that rewards coverage, so the assistant answers from a complete picture, not a lopsided top-k.
Evaluation harness
A curated, versioned set of representative and adversarial conversations scoring both answer quality and citation accuracy, gating every release and doubling as the evidence you show an auditor.
What clients get
A chatbot or voice agent whose answers are grounded in your knowledge, each one traceable to a verifiable source.
Provable data residency and access control that respects the underlying document permissions on every reply.
Retrieval that reasons across related documents instead of returning near-duplicate chunks.
A measured, gated conversational system you can defend in a compliance review.
