What we build

AI agent development
services.

An AI agent is software that uses a large language model to decide what to do next, calls your tools and systems to do it, and checks the result before moving on. A chatbot answers; an agent acts. These are the six kinds of agent UK businesses ask us for most.

01 — Documents

Document agents

Contracts, invoices, claims, reports and application forms read, checked against your rules, summarised and filed — with the source line quoted beside every extracted value.

02 — Workflows

Workflow & process agents

Multi-step work that crosses systems: reconcile the CRM with the ERP, raise the ticket, update the record, chase the missing field. Built on the same integrations your team already trusts.

03 — Customers

Customer service & chat agents

AI chatbot development that goes past FAQs: agents that look up the order, change the booking and escalate to a person with the whole conversation attached.

04 — Knowledge

Internal knowledge copilots

Retrieval-augmented (RAG) assistants over your policies, tickets and manuals, answering with citations — so staff can check the answer instead of trusting it.

05 — Real time

Real-time & voice assistants

Agents that listen alongside your people and prompt them live — as in Empath AI, which guides call-centre agents inside Microsoft Teams.

06 — Products

AI inside your product

Generative AI features added to the app or platform you already run — search, summaries, drafting, triage — without rebuilding what works. Broader ML and model work lives on our AI & ML development page.

How we build

How we build agents
you can trust.

Same senior engineers from the first workshop to handover. Weekly demos. No offshore rotation.

Pillar 01

One workflow, measured

We start with a single workflow and time it as it runs today. The agent is judged against that baseline — hours saved, error rate, turnaround — not against a demo.

Pillar 02

Guardrails and a human in the loop

Agents get the narrowest permissions that do the job, an audit log of every action, and a person's sign-off wherever a mistake would cost money, a customer or a regulator's attention.

Pillar 03

Model-agnostic, UK data

OpenAI, Anthropic Claude, Google Gemini or open-source models, chosen on accuracy, cost and privacy. Data stays in UK or EU regions, and swapping the model later does not mean rebuilding the agent.

Pricing

What an AI agent
costs in the UK.

Indicative Magora pricing for 2026, in GBP. Every engagement starts with a free working prototype, and the final figure is fixed after Discovery, when the workflow, integrations and data are known. Adding AI to an existing application typically runs £20,000–£80,000; ongoing support is £3,500–£9,000 a month.

£0 · 5–10 working days

Working prototype

A coded prototype of your agent on your own example documents or data, before you commit to anything.

From £3,000 · 2 weeks

Discovery sprint

Workflow map, baseline, risks, data-protection review and a fixed estimate — yours to keep, whoever builds it.

From £15,000 · 4–6 weeks

AI proof of concept

The agent running on real data in a controlled pilot, with evaluations that show whether it is good enough to scale.

From £20,000

AI agent for internal automation

One production workflow automated end to end — document, process or triage agent — with guardrails, audit log and monitoring.

From £30,000

Knowledge agent (RAG)

Retrieval pipeline, vector database and API over your document estate, answering with citations and access control.

From £40,000

Production LLM application

Customer-facing or multi-agent systems at production grade. Larger multi-agent programmes typically take 3–6 months.

Process

From workflow
to working agent.

A production AI agent for a single workflow typically ships in 6–8 weeks after Discovery.

Step 01

Workflow audit

1 week

We sit with the people who do the work, map every step and exception, and record how long it takes today. Some workflows fail this test: a simple automation or an off-the-shelf tool would do, and we say so.

Workflow map Baseline Build vs buy
Step 02

Free prototype

5 – 10 working days

A coded agent running on a sample of your real inputs, so the first conversation about accuracy is about evidence rather than promises.

Real data sample Model shortlist
Step 03

Evaluations & guardrails

1 – 2 weeks

A test set of real cases with known right answers, run automatically on every change. Permissions, approval steps and data-protection rules are agreed and written down.

Evals in CI Permissions GDPR
Step 04

Build & integrate

4 – 8 weeks

The agent is connected to your CRM, ERP, inbox, document store or Teams, with every tool call logged and every failure alertable. Weekly demos on your data.

Tool calling Integrations Audit log
Step 05

Supervised pilot

2 – 3 weeks

The agent works alongside your team, who approve or correct its output. Corrections feed the test set; results are measured against the baseline from step one.

Step 06

Run & improve

Ongoing

Monitoring of accuracy, cost per task and drift; a runbook for your team; and a plan for when the process, the data or the model changes.

Frequently asked

AI agents:
the honest questions.

Before you commit, read our checklist is your business ready for an internal AI agent?

How much does AI agent development cost in the UK?

At Magora, an AI agent that automates one internal workflow starts from £20,000. An AI proof of concept starts from £15,000 (4–6 weeks), a knowledge agent with a RAG pipeline from £30,000, and a production LLM application from £40,000. Adding AI to an existing application typically costs £20,000–£80,000.

Every project starts with a free working prototype and a Discovery sprint from £3,000, after which the price is fixed.

What is the difference between an AI agent and a chatbot?

A chatbot answers questions. An AI agent takes actions: it plans the steps, calls your systems through their APIs — CRM, ERP, email, document store — checks what came back and either finishes the task or hands it to a person. Many projects start as a chatbot and become an agent once the answers are trusted.

How long does it take to build an AI agent?

A coded prototype takes 5–10 working days and is free. A production agent for a single workflow typically ships in 6–8 weeks. Multi-agent systems and agents spanning several departments run 3–6 months end to end.

Which workflows suit an AI agent first?

High-volume, rules-heavy work that people do by reading and re-typing: document intake and checking, data entry between systems, first-line triage of emails and tickets, and internal questions answered from policies and manuals. Work that needs judgement on every case, or where one mistake is very costly, comes later — with a person approving each decision.

What stops an AI agent from doing something wrong?

Design, not hope. The agent gets only the permissions its task needs, anything irreversible or high-value waits for human approval, every action is written to an audit log, and an evaluation suite of real cases runs on every change so a regression is caught before release rather than by a customer.

Do we need a custom agent, or will Copilot or ChatGPT do?

If the job is drafting and summarising for one person at a time, an off-the-shelf assistant is usually enough, and we will tell you so. A custom agent pays off when the work runs across your own systems, has to follow your rules, needs an audit trail, or has to run without someone typing a prompt.

Which AI models do you use, and where is our data stored?

OpenAI, Anthropic Claude and Google Gemini, or open-source models such as Llama, Mistral and Qwen when data must stay on your own infrastructure. Deployments default to UK or EU regions on AWS or GCP, GDPR compliance is built in, and an EU AI Act readiness review is part of Discovery.

Who owns the AI agent you build?

You do. Source code, prompts, evaluation sets and IP transfer to you on payment, and the agent runs in your cloud account. Because it is model-agnostic, you are not locked to one AI vendor or to us. We sign an NDA on day one.

Have a workflow
an agent could run?

30-minute call with a senior AI engineer. Bring one process your team repeats every day — we'll tell you whether an agent is worth building, and what it would cost.
