What is an AI agent and how does it work?

New AI agents are constantly being touted but accessible and practical information about them is scarce. You're often met with either aggressive sales tactics or overly technical explanations.

Many CX leaders and ops managers are caught in this spot. Meanwhile, AI is racing ahead. According to Gartner, by 2028, 15% of everyday work decisions will happen through agentic AI. That’s not a future problem. That’s now!

You can connect the dots in this guide—no jargon, no hype. Just real, useful clarity on AI agents and how they can reshape how your team supports customers.

What is an AI agent?

An AI agent is a software-based system that can sense its environment, process information, make decisions, and take action without constant human input. Think of it as a virtual assistant with decision-making skills.

In customer support, an AI-powered virtual agent can instantly respond to FAQs, route tickets to the right teams, or suggest relevant help articles in real time.

It understands intent, context, and customer history. That’s what makes it more than a chatbot. It’s a true intelligent agent in AI terms, designed to act with purpose and learn over time.

What are the different types of AI agents?

There are five broad types of AI agents, each with varying levels of intelligence and decision-making capability. Here’s a quick rundown of how they show up in customer support:

• Simple reflex agents: These respond to specific inputs with preset rules. Example: A virtual agent that replies, “We’re looking into it,” whenever it sees the word “issue.” It’s fast, but not very smart.

• Model-based agents: These use internal data to decide how to respond. In support, this could mean an AI agent that looks at a customer’s past interactions to choose the next best action.

• Goal-based agents: These agents make decisions based on a defined outcome, like resolving tickets within 24 hours. They work well in automation that aims for clear targets, such as SLAs or CSAT goals.

• Utility-based agents: These go further by weighing different options and choosing the best one. For example, rerouting a ticket not just to any available agent but to the one with the highest resolution rate.

• Learning agents: These get smarter over time. A classic example is an AI virtual agent that improves its responses based on past chats or feedback. It adapts and evolves with each customer interaction.

How AI agents work

An AI agent works like a smart, behind-the-scenes operator. It takes in data, understands what’s going on, and decides what to do next—all in a few seconds.

Here’s a summarized view of how they work:

• Data ingestion: This is where everything starts. The agent collects inputs, such as customer messages, past interactions, or behavioral signals. Without this data, it wouldn’t have the context it needs to make accurate decisions.

• Training: Before the agent can take action, it needs to learn. Training involves feeding it real examples so it understands what helpful responses look like. Think of it as onboarding—only faster and ongoing.

• Processing with AI models: When new input arrives, the agent uses Natural Language Processing (NLP) to understand the message and Machine Learning (ML) to predict the best next step. This is how it figures out intent, urgency, and relevance in real time.

• Decision-making: Based on what it’s learned, the agent decides what to do—respond, escalate, tag, or summarize. This step ensures customers get the right help at the right time.

• Reinforcement learning: AI agents don’t stay static. They learn from every interaction—what worked, what didn’t—and use that feedback to get smarter and more accurate over time.

Understand it better through an example: Let’s say a customer types, “My payment failed, but I was charged.” The intelligent agent in AI immediately identifies the issue type, pulls up relevant past resolutions, and either replies with a helpful fix or routes it to a billing expert, depending on what it’s learned works best.

This whole process takes seconds. Because it’s built using a flexible AI agent framework, the logic can scale across thousands of support tickets without compromising quality.

How AI agents help you with your customer support

Customer service is on the edge of a major shift. By 2029, agentic AI is expected to autonomously resolve 80% of common support issues, with zero human input. That’s not a distant future; it’s the path we’re already on. So, what does that look like in practice? Here’s how these agents are already transforming support workflows:

• Auto-triaging tickets: Instead of manually sorting through incoming issues, AI agent frameworks can instantly tag and route tickets by topic, urgency, or customer type. This means fewer delays and faster resolution for high-priority cases.

• Summarizing conversations: Long customer complaint threads? No problem. AI agents can quickly scan and summarize past customer service interactions, pulling out the key points, issues raised, and actions taken. This gives support agents the full context at a glance, without needing to read through every message. It speeds up response time and ensures nothing important gets missed.

• Auto-drafting responses: The agent can suggest full replies for common issues like password resets or delivery delays. Agents just review and send, cutting response time significantly without compromising quality.

• Flagging risky or sensitive chats: AI agents can detect negative sentiment or frustration in messages and alert supervisors. That way, sensitive cases don’t get missed.

• Helping new agents onboard faster: When agents get stuck, the AI virtual agent can suggest similar past solutions, turning knowledge from your entire support history into instant, actionable help.

  The result? Less grunt work, faster support, and a smoother experience for customers and agents.

AI agents vs. chatbots vs. human agents: What's the difference?

Most of us are already familiar with chatbots—they’re the pop-ups on websites that help answer FAQs, guide you through returns, or hand you off to a live agent. They’re fast and helpful, but usually stick to a fixed script.

So it’s only natural to wonder: if chatbots are already doing the job, why move to something new like an AI agent? The answer lies in how these tools think, act, and scale. Let’s break down what sets AI agents apart from traditional chatbots and human agents so you know when to use each and how they can work together to deliver better customer support.

AI doesn’t replace—It works with you

“AI agents will become our digital assistants, helping us navigate the complexities of the modern world. They will make our lives easier and more efficient.” — Jeff Bezos, Founder and CEO of Amazon

That’s exactly what modern support teams need—not another tool to manage, but a digital assistant that quietly handles the repetitive stuff so agents can focus where it counts.

Imagine a customer asking why their account was deactivated. A chatbot handles the greeting, verifies account info, and flags a billing issue. An AI agent takes over in the background, cross-referencing activity, identifying a login risk, and drafting the next best action. The human agent steps in with full context, a suggested resolution, and time to focus on tone and reassurance.

That’s not a replacement—it’s teamwork.

An AI-powered virtual agent clears the clutter, tagging tickets, routing them, and summarizing threads. It gives your team time back—time they can spend solving complex issues, de-escalating frustration, and actually being present for customers.

The smartest support teams don’t choose between bots and people. They let each do what they do best, resulting in faster, wiser, and more human support at scale.

Benefits of using AI agents in customer support

By this point, it’s clear that an AI agent does more than automate responses. It changes how your support engine runs. But what does that look like in terms of measurable outcomes? Here are five benefits that directly impact your support team’s performance, customer experience, and bottom line:

1. Respond to customers 3x faster, even during peak hours

AI agents don’t get overwhelmed. While human agents struggle to handle multiple chats or emails, AI handles thousands of interactions simultaneously without missing a beat. That means no queues, delays, or “we’ll get back to you shortly” during high-volume spikes.

Data speaks: Companies using AI in support report a 37% drop in first response times compared to those who don’t.

Freshdesk, an AI-powered customer service platform with built-in AI agents, can handle high volumes, automate responses, and keep resolution times low, even during peak hours.

2. Free up to 40% of agent time for high-value work

Tagging tickets, assigning priorities, and handling basic queries consume nearly half of your agents’ time. A well-trained AI-powered virtual agent takes care of these tasks in real time, freeing your team to focus on escalations, problem-solving, and meaningful customer conversations.

3. Improve CSAT by giving agents better context

When agents are handed full conversation summaries, customer history, and sentiment analysis—all pre-processed by the AI agent—they show up better prepared. That leads to faster resolutions, fewer escalations, and more confident, competent support.

Data speaks: Freshdesk ensures a 96% average customer satisfaction score with its people-first (human-like) AI.

4. Reduce ticket handling errors by automating the tedious bits

Mistakes often happen in repetitive, manual workflows—wrong routing, missed tags, or copy-paste reply errors. An intelligent agent in AI automates these with precision, reducing friction points that silently erode customer trust.

Data speaks: Businesses that automate their ticket resolution process with AI experience a 52% faster turnaround than those relying on manual methods.

5. Scale support without scaling headcount

Growth usually means hiring. But with AI agents handling the frontlines, you can handle more customers without bloating your team. It’s not about replacing people—it’s about scaling smart.
