CLIENT STORIES / AI4U

Trustworthy AI answers for regulated industries.

We built AI4U an answer system for industries where the quality of information is critical. It answers from verified sources, shows where each answer comes from and hands uncertain questions to a person.

AI4U support inbox on a laptop, demo workspace with sample data: conversations marked AI answered, escalated and human handled.

One example use case: customer questions answered from verified sources, with escalations to a person. AI4U support inbox, demo workspace with sample data.

AI4U on a phone: a customer question on UK VAT answered with a cited official source (HMRC, GOV.UK). Sample conversation.

01

THE CHALLENGE

Answers had to be fast, accurate and traceable.

AI4U needed an answer system for regulated industries, where the quality of information is critical. Answers had to draw on internal reports, government databases and industry research, and stay accurate, traceable and compliant. A basic search tool could not do that.

Two overlapping knowledge sources: Source 01 public knowledge (external) and Source 02 private knowledge (internal), meeting in one system, one place to ask.

SOURCE 01

Public knowledge

External: government reports, academic research, industry databases

SOURCE 02

Private knowledge

Internal: documents and institutional knowledge

One system

One place to ask

01

Understand context

It had to grasp nuanced questions, not just match keywords like a basic search tool.

02

Answer from verified sources

It had to bring public and private information together and answer only from sources that could be checked.

03

Stay secure and compliant

Everything had to stay secure and compliant with UK regulations, with a person stepping in when an answer was uncertain.

02 — WHAT WE DELIVERED

One answer system. Built on verified knowledge.

We built an AI answer system that works like a knowledgeable expert on hand. It finds information across public and private sources and answers from what it can verify.

Institutional knowledge

ONE QUESTION

A single answer can draw on public and private sources together.

01 / OUR CONTRIBUTION

We connected public sources.

Government reports, academic research and industry databases.

02 / OUR CONTRIBUTION

We integrated private sources.

Internal documents and institutional knowledge, connected securely.

03 / OUR CONTRIBUTION

We added smart retrieval.

The system finds the relevant, verified information before it writes a response.

04 / OUR CONTRIBUTION

We customised the AI engine.

We selected an open-source AI model and adapted it to AI4U’s specific needs.

05 / OUR CONTRIBUTION

We built in security.

Privacy controls, access controls, encryption and complete audit trails for accountability.

BUILT TO KEEP IMPROVING

The system gets better the more it is used.

Built-in learning capabilities help the system get better over time, so answers keep improving with use.

03 — HOW WE BUILT IT / DELIVERY DETAIL

How we built it, in detail.

We built an answer system that brings together public and private knowledge, supported by a carefully selected and fine-tuned open-source language model.

The aim was answers people in regulated industries can rely on: grounded in verified sources, easy to check, and handed to a person when the system is not sure.

CONTEXT FOR NON-TECHNICAL READERS

RAG

Retrieval-augmented generation. Before answering, the system finds the relevant information, then writes its response from it.

FINE-TUNED OPEN-SOURCE LANGUAGE MODEL

The engine behind the answers

A language model is the AI that reads a question and writes the reply. Open-source models are openly available to run and adapt. Fine-tuning customises one for a specific organisation’s needs.

GDPR

Data protection and privacy controls for GDPR, the UK and EU data-protection law.

Access

Users only see information they are authorised to access.

Encryption

Data stays secure through encryption and proper handling.

Audit

Complete audit trails for transparency and accountability.

HOW WE BUILT IT / 4 PHASES

SCOPE: DISCOVERY → DEPLOYMENT

01

Discovery and planning

We started with in-depth conversations with stakeholders to understand day-to-day challenges. We mapped existing data sources, found where people were getting stuck and defined what success would look like.

02

Development and integration

We structured the knowledge database and fine-tuned the chosen language model. We built a secure connection layer between the AI and both public and private sources, focusing on speed and accuracy.

03

Testing and optimisation

Extensive testing showed where to improve. We refined how information is retrieved, improved response quality and made sure everything met UK regulatory requirements.

04

Deployment and training

We launched the system in a secure cloud environment and trained AI4U’s team to get the most out of it. Monitoring tracks how well it works and where to improve next.

CHALLENGE 01

Giving accurate answers quickly, from scattered sources.

HOW WE ADDRESSED IT

We connected public and private sources to one system that understands context and retrieves verified information before it answers.

CHALLENGE 02

Keeping sensitive knowledge secure and compliant with UK regulations.

HOW WE ADDRESSED IT

We built in GDPR-ready privacy controls, access controls, encryption and complete audit trails, and tested against UK regulatory requirements.

04 — HOW WE WORKED TOGETHER

One team around AI4U’s knowledge.

PQ Impact led the project from discovery to launch. We worked with AI4U’s stakeholders to understand their daily challenges, then trained their team to get the most out of the system.

PQ IMPACT

Build the system

Knowledge database, language model fine-tuning, a secure connection layer, testing and cloud deployment.

PQ IMPACT + AI4U

Map the knowledge

Stakeholder conversations, existing data sources, where people got stuck and what success would look like.

AI4U TEAM

Put it to work

Trained to get the most out of the system, with monitoring in place to guide further improvement.

A TECHNICAL DECISION IN PRACTICE

Open-source, not proprietary.

THE CONSTRAINT

Proprietary AI solutions are expensive and limit long-term control.

THE DECISION

Select an open-source language model and customise it for AI4U.

WHAT WE DELIVERED

Lower AI costs, long-term control and a modular design that is easy to update.

WHAT IMPROVED

EFFICIENCY

Faster

Faster information access, quicker decisions on complex issues and more reliable information across searches.

COST

Lower cost

Lower AI costs through open-source technology, less time on manual research and faster project delivery.

DECISIONS

Better informed

Real-time access to current information, insights that combine external trends with internal data, and consistent responses.

ARCHITECTURE

Room to grow

New data sources and users can be added, and the same approach adapts to other regulated areas. Open source keeps long-term control.

ONE EXAMPLE USE CASE · DEMO WORKSPACE

One example: customer questions on UK VAT

This is one way AI4U is used, shown in its own product with sample conversations. When verified sources contain the answer, AI4U replies and cites them. When a question needs a team decision, it escalates and prepares a draft for a person to review. The same approach works in other regulated areas.

AI4U on a phone: a customer question on UK VAT answered by AI, citing an official HMRC source on GOV.UK. Demo workspace, sample conversation.
