Private AI Knowledge Systems for UK Businesses

A RAG knowledge system is an AI assistant that answers from your own documents with cited, auditable sources instead of guessing. MicroPyramid builds private RAG-powered copilots, support assistants, and semantic document search for UK professional services, legal, financial, and SaaS teams: query your internal knowledge in natural language, with source citations and role-based access.

The UK Knowledge Problem RAG Systems Solve

UK businesses (from City law firms and FCA-regulated fintechs to growing SaaS companies and public sector bodies) accumulate enormous volumes of structured and unstructured knowledge. Most of it sits inaccessible in SharePoint, Confluence, email threads, or PDF archives. When a colleague or customer asks a question, the answer exists somewhere, but finding it costs hours.

RAG (Retrieval-Augmented Generation) systems solve this by indexing your documents privately, retrieving the most relevant passages for each query, and returning a grounded answer with citations back to the source. No hallucination, no data leaving your environment, no off-the-shelf chatbot trained on public internet content.

Under UK GDPR and the DPA 2018, organisations are accountable for how personal data is processed and stored. Our systems are designed with that accountability in mind: data residency in AWS eu-west-2, access controls, audit logging, and the ability to deploy entirely on-premise if your DPO requires it.

What We Build for UK Teams

Six types of private RAG-powered knowledge systems, each shaped around UK compliance, data-residency, and sectoral needs

Internal Knowledge Copilot

Give your UK team a private retrieval assistant over internal policies, SOPs, compliance guides, and runbooks, with citations, role-based access, and full audit trail for ICO accountability obligations.

  • Document ingestion pipeline
  • Semantic retrieval with citations
  • Role-based access control

AI Support Assistant

Turn your existing support docs, product FAQs, and ticket history into an intelligent first-line assistant. Ideal for UK SaaS companies managing high support volumes from European and US customers.

  • Knowledge ingestion & indexing
  • Retrieval-backed answers
  • Fallback & escalation logic

Enterprise Document Search

Replace full-text keyword search with semantic retrieval across contracts, compliance filings, regulatory correspondence, and technical specs, built for the document-heavy realities of UK professional services.

  • Semantic search & ranking
  • Multi-format document support
  • Filters & faceted navigation

Legal & Compliance Q&A

Give legal, risk, and compliance teams instant retrieval over UK-specific regulatory guidance, FCA notices, ICO guidance, and internal policies, with source attribution so nothing gets misquoted.

  • Regulation & policy retrieval
  • Source-attributed answers
  • Access-controlled by team

Private Document Q&A

Secure, access-controlled Q&A over sensitive documents (client contracts, board papers, GDPR records of processing) deployed entirely within your private cloud or AWS eu-west-2 (London) region.

  • On-premise or private cloud
  • UK data residency (eu-west-2)
  • Audit logging

Secure RAG with Citations

Every answer is attributed to its source document with page-level citations, auditable, trustworthy, and safe for UK regulated industries from financial services to public sector procurement.

  • Source-attributed answers
  • Confidence scoring
  • Hallucination mitigation

Where UK Teams Get ROI

The strongest use cases share one trait: large, growing bodies of knowledge that people need to query, without waiting for a colleague

UK SaaS Support

Reduce ticket volume for support-heavy SaaS products serving UK and European customers, answers drawn directly from your docs, with escalation when confidence is low.

Professional Services

Help consultants, solicitors, and advisers search across engagement files, precedent libraries, and internal knowledge, without emailing colleagues or hunting through SharePoint.

Financial Services & FCA Compliance

Secure retrieval over FCA guidance, internal compliance manuals, and product disclosures. Cited answers reduce the risk of misinterpreting regulatory requirements.

Legal & Contract Intelligence

Let legal teams query contracts, matter files, and regulatory briefs in natural language. Answers are cited and auditable, critical for UK legal privilege and data handling obligations.

Public Sector & GovTech

Knowledge systems for UK government and public sector teams: policy retrieval, FOI preparation, and internal knowledge management with full data residency in the UK.

Product Documentation

Help UK-based users self-serve from product docs, API references, and release notes rather than opening tickets, reducing support overhead and improving customer satisfaction scores.

Best Fit For

  • you have a large body of policies, contracts, compliance docs, or product knowledge UK teams need to query
  • answers need citations and auditability, essential under UK GDPR accountability principles
  • you want a private assistant that keeps all data within the UK or your own infrastructure
  • you need retrieval-backed answers grounded in your own regulated data

Not the Right Fit When

  • you mainly need AI embedded inside an existing product workflow rather than a standalone knowledge system
  • your source content is thin, outdated, or not ready to index
  • you expect autonomous answers without guardrails or human review in regulated workflows
  • the goal is a public-facing generic chatbot with no grounding in your own documents

If you need AI inside an existing product workflow, start with AI Feature Development instead.

Frequently Asked Questions

Straight answers to what UK founders, CTOs, and compliance leads ask before building a RAG knowledge system.

What is a RAG knowledge system?

A RAG (retrieval-augmented generation) knowledge system is an AI assistant that retrieves the most relevant passages from your own documents and uses them to generate an answer with cited sources, instead of relying on what a language model memorised from the public internet. Because every answer is grounded in your content and attributed to its source, it stays accurate, auditable, and current as your data changes, which is what makes it safe for UK regulated work.

Can you build a UK GDPR-compliant RAG system with UK data residency?

Yes. We deploy by default in AWS eu-west-2 (London) so your documents and embeddings stay in the UK, and we can run the entire system on-premise or in your own private cloud if your DPO requires it. We build with UK GDPR and the Data Protection Act 2018 in mind from day one: data minimisation, role-based access controls, and full audit logging that supports your ICO accountability obligations.

How is a custom RAG system different from Microsoft 365 Copilot or Glean?

Off-the-shelf copilots like Microsoft 365 Copilot or Glean work well when your knowledge already lives entirely inside their ecosystem and generic answers are acceptable. A custom RAG system is the better choice when you need answers grounded in data they don’t reach, page-level citations, your own access rules, UK data residency or on-premise deployment, or a copilot embedded in your own product, and when you want to own the system outright rather than rent per-seat licences indefinitely.

How do you stop the AI from hallucinating or inventing answers?

Every answer is grounded in retrieved passages and attributed with page-level citations, so a user can verify the source before trusting it. We add confidence scoring, fallback and escalation logic when retrieval is weak, and an evaluation pass on your real questions before launch, so the system says “I don’t know” or escalates to a human rather than making something up. For UK regulated teams, that auditability is the difference between a usable tool and a compliance risk.

Can it work for FCA-regulated or public-sector teams?

Yes. Cited, access-controlled retrieval is a strong fit for FCA-regulated firms, legal and compliance teams, and UK public sector bodies: secure Q&A over FCA guidance, internal compliance manuals, contracts, and policy libraries, with source attribution so nothing gets misquoted. Data residency in the UK, audit logging, and per-team access controls are designed in, not bolted on, so the system can sit inside regulated and FOI-sensitive workflows.

How long does it take to get a working system, and how does billing work?

A discovery sprint produces a working prototype in days, and a production knowledge copilot with ingestion, citations, and access control typically ships in weeks rather than months, because we use AI-assisted engineering and scope the smallest valuable version first. UK clients are invoiced in GBP via Stripe or GoCardless Direct Debit (no US-dollar conversion overhead) and our India team overlaps around 4.5 hours with UK business mornings for live standups and reviews.

Do we own the source code and IP?

Yes. You own all source code and intellectual property we build, committed to your repositories as we go, so there is no vendor lock-in if you later bring the system fully in-house. The same senior engineers who run discovery write the code and stay reachable on Slack. You are not handed off to an account manager once the build starts.
