IN PLAIN ENGLISH

What Is RAG Development – and What We Do Differently

RAG (retrieval-augmented generation) finds the most relevant parts of your documents first, then asks the AI to answer using only those parts. That is how you get answers that are specific to your business and can be checked. Most RAG demos work on ten files. We build for thousands, with permissions, updates and measured accuracy.

SOUND FAMILIAR?

Business Problems Our RAG Development Solves

Staff Spending Hours Searching for Information

The answer exists somewhere in a shared drive, but finding it takes twenty minutes and three messages to colleagues. RAG finds it in seconds.

AI Chatbots That Make Things Up

A general AI model guesses when it does not know. RAG makes it answer from your documents and show where each answer came from.

Knowledge Locked in a Few Experienced People

When the person who knows leaves or is on holiday, work stops. RAG makes that knowledge searchable for everyone who is allowed to see it.

New Starters Taking Months to Get Up to Speed

Policies, procedures and product details are spread across many systems. A RAG assistant gives new staff answers on day one.

WHO USES IT

RAG Use Cases by Department

RAG for Sales Teams

Sales staff ask for prices, specs or contract terms and get an answer with the source document linked, in seconds.

RAG for Marketing Teams

Marketers check brand guidelines, past campaigns and product facts before they write, so copy stays accurate.

RAG for Customer Support

Agents and customers get answers drawn from your real help centre and policies, with links back to each source.

RAG for Operations & Admin

Staff find the right procedure, form or safety note without scrolling through shared drives or asking a colleague.

RAG for Finance & Reporting

Finance teams search contracts, invoices and policy documents in plain English instead of opening folder after folder.

RAG for HR & Recruitment

New starters ask the handbook questions directly and get the current policy, not the version from three years ago.

HOW WE WORK

How Our RAG Development Process Works

  1. AI Opportunity Audit

    We review the documents you want the AI to use: where they live, how often they change and who is allowed to see what.

  2. Roadmap & ROI Forecast

    We agree the questions the system must answer well, the accuracy target and the hosting set-up, with a clear cost.

  3. Build & Integrate

    We prepare and index your content, build the retrieval pipeline and connect it to the chat or search screen your team will use.

  4. Test, Train Your Team & Launch

    We test against a set of real questions with known answers, fix weak spots, then train your team and go live.

  5. Monitor, Optimise & Scale

    We watch which questions fail, add missing content, re-index new documents and keep answer quality measured over time.

TECHNOLOGY

AI Models & Platforms We Work With

We are not tied to one vendor. We choose on accuracy, cost and where your data needs to live.

AI Models (OpenAI GPT, Claude, Gemini, Llama)

Chosen for answer quality and cost, with private hosting options when documents must stay in the UK or EU.

RAG Frameworks & Vector Databases

LangChain, LlamaIndex, Pinecone, Weaviate, Qdrant, pgvector and Azure AI Search, chosen to suit your data size.

Document Sources & Business Tools

SharePoint, Google Drive, Confluence, Notion, Zendesk, websites, PDFs and databases, kept in sync automatically.
