What Are AI Agents and How Do They Work?

Gareth Arnold Gareth Arnold -

If you’ve been exploring ways to make your customer journey smoother or reduce pressure on your team, you’ve probably seen the term AI agents appearing more and more. These aren’t basic chatbots or one-off automation scripts; they’re digital team members that can take real action inside your business.

At SystemsX, our AI Agents are designed to plug into your existing systems, support customers in real time and help your people focus on the work that truly matters.

In this guide, we’ll walk through what AI agents are, how they work, how they can be customised, and why integration with your existing systems can transform your operational efficiency and customer experience.

What Is an AI Agent?

To understand what an AI agent is, it helps to start with insights from trusted, non-commercial sources. McKinsey defines an AI agent as “a software component that has the agency to act on behalf of a user or system to perform tasks.”

Government research bodies like NIST also highlight AI’s growing capacity for autonomous action, decision-making and responsible behaviour within defined boundaries.

AI agents don’t just answer - they act.

They are capable of performing tasks such as qualifying enquiries, managing bookings and service conversations, and directly connecting to your systems. Retrieve, share, and act on live information in real time. AI agents can even work across chat, phone, portals, and websites.

A combination of autonomy and system connectivity makes an AI agent a true digital team member.

How Do AI Agents Work?

Understanding how AI agents work means looking at their core loop:

perceive → decide → act.

Microsoft explains that AI agents “observe their environment, interpret data, and take actions toward specific goals.”

FreeCodeCamp expands on this, explaining how agents gather context, analyse information and execute multi-step actions without needing manual intervention.

Our AI Agents follow this same structure, but with a business-first focus. They can:

  • Understand customer questions

  • Look up live information from your systems

  • Complete bookings or payments

  • Process service requests

  • Escalate to human teams when needed

  • Operate across channels, including phone, chat and portals

Customers receive fast, clear, consistent support, and your team gains time back.

Can AI Agents Be Customised for Specific Business Needs?

Absolutely, and customisation isn’t optional; it’s the foundation of how their AI Agents work.

Every organisation has its own language, priorities and processes. We build each Agent to align with your brand voice, customer experience goals and operational workflows. Customisation includes:

  • Task definition: deciding what the agent should handle vs. what stays human-led

  • Tone & language: shaping responses to match your service style

  • Workflow logic: setting rules, guardrails and escalation points

  • Data access: enabling only the permissions and systems your business approves

This creates an agent that feels supportive, consistent and aligned with how your organisation already operates.

Can AI Agents Handle Sensitive Customer Conversations?

A common question is whether AI agents can manage sensitive information. The answer is yes when configured correctly. Our AI Agents operate using your approved rules and connected systems, which means:

This gives customers clarity and reassurance, while helping your team maintain high service standards.

How AI Agents Integrate With Your Existing Systems and Why It Matters

One of the biggest strengths of our AI Agents is that they don’t require you to change your systems. Instead, we connect seamlessly to your existing systems. This means your AI agent becomes part of your real operational environment.

Through integration, the agent can:

  • Pull real-time data from your booking or update CRM systems

  • Update records instantly

  • Check availability

  • Process tasks end-to-end

  • Provide consistent answers based on shared data

Why integration is so important

Customers feel supported with quick, accurate responses. Your team feels lighter, with fewer repetitive tasks. You gain efficiency because everything works within your existing ecosystem. You can scale by adding more automation without rebuilding your stack. Integration is what transforms an AI agent from a conversational tool into a true digital colleague.

AI agents are already reshaping how organisations support their customers and teams. Giving you a practical, supportive way to introduce them into your operations.
