Businesses evaluating AI customer service often face the same question: What is the difference between an AI Agent and an AI Chatbot?

Both can communicate with customers and handle certain customer service tasks. The more important question, however, is how deeply each can participate in the service process: is it mainly answering common questions, or can it also understand customer needs, move tasks forward, and hand conversations over to human agents when necessary?

For businesses that mainly need to handle FAQs, a chatbot may be enough. When customer requests involve multiple steps, workflows, or more complex issues, an AI Agent may be more appropriate.

Why Do Businesses Need to Distinguish Between AI Agents and AI Chatbots?

When choosing customer service AI, it is easy to assume that being able to “chat” means being able to complete customer service tasks.

In reality, conversation is only one part of customer service.

Getting an Answer Does Not Always Mean the Problem Is Solved

Imagine a customer asks, “What is your delivery policy?”

If the system can find the relevant information from the company’s existing knowledge and provide an answer, this is a typical chatbot scenario.

But if the customer follows up with, “Where is my order now? If it hasn’t shipped yet, I want to change the delivery address,” the request becomes more complicated.

The system may need to understand what the customer wants, retrieve order information, check whether the change is allowed, and then determine what should happen next. If it cannot complete the request, the conversation may need to be handed over to a human agent.

So when evaluating AI capabilities, a more useful question is not:

“Can this tool answer questions?”

It is:

“Can it help move the customer’s request forward?”

Businesses Need Workflows, Not Just a Chat Window

Real customer service rarely ends with a single question and answer.

A request may involve knowledge retrieval, information verification, ticket creation, team handoff, or follow-up. If AI stops at the answer stage, many of these tasks still have to return to human agents.

That is why businesses should evaluate conversational capabilities together with the workflows they support.

What Customer Service Tasks Are AI Chatbots Better Suited For?

For many businesses, a chatbot is a straightforward starting point for automation.

FAQs and Routine Information Requests

A large number of customer questions do not need to be answered manually every time.

Product information, service details, business hours, common policies, and basic usage guidance can often be handled by a chatbot when the business has a clear and stable source of information.

Udesk’s AI Chatbot product page positions FAQ handling and automation as key capabilities, while also supporting handoff to human agents when needed.

For customer service teams, this means employees do not have to repeatedly provide the same information, while customers can get answers without waiting for an agent.

When Customers Simply Want to Confirm Something

Not every customer enquiry requires a complex service process.

A customer may simply want to know the opening hours, confirm a policy, or check whether a product meets a particular requirement. In these situations, what matters most may be getting a clear answer quickly rather than having a full conversation with a human agent.

A chatbot can provide this first layer of response and leave human agents more time for issues that actually require their involvement.

What Customer Service Tasks Can AI Agents Handle?

The difference between an AI Agent and a chatbot becomes more visible when a customer request goes beyond a simple answer.

Moving From Answering Questions to Moving Tasks Forward

After a customer makes a request, there may be several steps that need to happen next.

In these situations, AI needs to do more than generate a response. It needs to understand the task, access relevant information, and continue according to the defined workflow.

Udesk’s current Omnichannel Customer Service Solution page describes AI Agents as capable of handling common questions together with workflow automation. It also presents different AI Agent capabilities, including Conversation & Guidance Agent, Call Agent, Agent Assist, and VOC Agent.

From an operational perspective, this means AI can participate in more than the “answer” itself. It can become part of the next step in the customer service workflow.

More Complex Requests Require More Context

Customer questions are rarely completely isolated.

The same customer may first ask about a product, then check an order, and later raise an after-sales request. If every interaction is treated as an entirely new conversation, the customer may have to repeat the same background information.

For more complex customer service scenarios, businesses therefore need to consider not only how well AI answers a single question, but also what the customer is currently trying to do, what has already happened, and what should happen next.

The ability to connect knowledge, context, and workflows is one of the more practical differences between an AI Agent and a simple question-and-answer chatbot.

What Is the Practical Difference Between an AI Agent and a Chatbot?

From a customer service operations perspective, the distinction can be simplified.

One Focuses on Answering, the Other on Moving Work Forward

A common chatbot flow is:

Customer asks a question → AI provides an answer

A deeper agent workflow can look like this:

Customer makes a request → AI understands the intent → retrieves information → moves the task forward → hands off to a human when necessary

This does not mean that all chatbots can only answer FAQs, or that every AI Agent can independently complete complicated tasks.

The real question is what level of capability the business actually needs.

If the customer only wants to know something, answering may be enough.

If the customer wants to complete something, the business needs to consider workflows, context, and task handling as well.

A Chat Window Is Not the Same as a Customer Service Workflow

When evaluating tools, businesses can easily focus too much on the front-end interface.

But once a system is used in daily operations, teams also need to answer practical questions:

Who should receive the customer’s request?

What happens if AI cannot resolve it?

Who handles a case that needs to become a ticket?

What happens to the previous conversation if the customer continues on another channel?

These questions determine whether AI actually reduces work or simply creates another customer service entry point.

A Real Example: How Schneider Electric Combines Chatbot and Knowledge Management

Schneider Electric provides a useful example of how chatbot capabilities can fit into enterprise customer service.

According to the Udesk customer case, Schneider Electric faced challenges related to fragmented customer service channels, the need for timely responses, and limited access to the knowledge required for more complex customer enquiries. Udesk provided an online customer service platform and combined intelligent chatbots with a KCS Knowledge Base to build a more complete service approach.

Chatbot Handles High-Volume, Repetitive Enquiries

Schneider Electric uses an intelligent chatbot to provide 24/7 rapid responses for simple and repetitive customer enquiries.

This highlights a clear chatbot use case:

High-volume requests + relatively stable answers + a need for quick responses.

In these situations, there is little reason for human agents to repeatedly handle the same basic questions.

Knowledge Management Supports More Complex Human Service

The Schneider Electric solution did not stop at the chatbot.

Udesk also integrated KCS Knowledge Base and enterprise search to help customer service agents access information more effectively and handle more complex enquiries. According to the Udesk case study, these knowledge capabilities helped agents provide more accurate, professional, and in-depth responses.

This is one of the most useful points from the case:

Automation does not have to stand alone. It can work together with knowledge management and human customer service as part of one service process.

The chatbot can handle high-frequency questions at the front end, while more complicated requests can still be handled by human agents with the relevant knowledge and judgment.

What Does This Case Mean for AI Selection?

The Schneider Electric case should not be reduced to the idea that a chatbot is “better” than human service.

It shows a division of responsibilities:

Automation handles tasks suitable for automation, while a knowledge system supports human agents with more complex customer needs.

For businesses, this means evaluating not only how many features a chatbot has, but also how well it can connect with existing knowledge, teams, and workflows.

Which Customer Service Scenarios Are Better Suited to AI Chatbots?

Businesses can start with tasks that are relatively easy to define.

High-Volume and Repetitive Routine Questions

When customers frequently ask similar questions and the answers are based on stable business information, chatbots are often a suitable option.

This can reduce repetitive work for human agents while giving customers a faster first response.

Moments When Customers Simply Need a Quick Answer

For example, a customer may be browsing a product or service page and suddenly have a small question.

In these situations, they may not need a complete customer service process. They simply want the issue clarified quickly.

A chatbot can serve as the first response layer and hand the conversation over to a human when necessary.

Which Customer Service Scenarios Are Better Suited to AI Agents?

When the task starts to involve several steps, there is more to consider.

Requests That Require Multiple Actions

Some customer requests are not naturally a simple question-and-answer exchange.

A customer may need to provide information, ask the company to retrieve a record, and then complete another action. If all of this depends on a human agent, the process can involve several handoffs.

An AI Agent can take a more active role in these workflows and move customer service beyond simple question answering.

Services That Depend on Customer Context

What the customer has said before, what they are currently trying to do, and whether a ticket has already been created can all affect how a case should be handled.

Businesses therefore need to consider whether an AI system can connect with relevant business information and customer service workflows rather than evaluating conversational ability alone.

When Should Human Agents Take Over?

Deploying AI does not mean every customer issue should be automated.

When AI Cannot Reliably Resolve the Issue

If AI cannot find reliable information or cannot continue the current task, keeping the customer in an automated conversation usually does not help.

The better option is to provide a human handoff while preserving as much of the existing conversation context as possible.

Customers should not have to repeat everything they have already explained.

When Judgment or Complex Handling Is Required

Complaints, special requests, sensitive situations, and cases involving multiple teams may require human involvement.

The difficulty in these situations is often not whether there is an answer, but whether the right judgment can be applied to the specific case.

A practical AI customer service system therefore needs to define clearly what AI should handle and where human agents should take over, rather than trying to maximize automation at every stage.

How Should Businesses Choose? Start With the Task, Then Evaluate the Product

When comparing AI Agents and chatbots, businesses can start by looking at their customer service work itself.

First, Look at What Customers Ask Most Often

Review a period of customer enquiries and identify the questions that appear most frequently.

If most are similar, routine questions, a chatbot may be a reasonable starting point.

Then Ask What Happens After the Answer

If the customer’s issue ends once they receive an answer, a question-and-answer capability may be sufficient.

If the answer is only the first step in a larger process, businesses should look more closely at AI Agents, workflows, routing, and connections with business systems.

Finally, Define Where Human Handoff Happens

Businesses should decide in advance:

When can AI continue handling the request?

When must it be transferred to a human?

What information should travel with the conversation?

These decisions have a direct impact on whether automation actually reduces the workload of the customer service team.

AI Agents and Chatbots Can Work Together

Businesses do not necessarily need to treat AI Agents and chatbots as mutually exclusive choices.

In a complete customer service process, a chatbot can handle high-volume, straightforward enquiries first. More complex requests can move into an AI Agent or another workflow, while human agents can step in when judgment, communication, or exception handling is required.

The resulting service path might look like this:

Customer raises a question → AI understands the need → answers or moves the task forward → hands off to a human when necessary → preserves context for continued handling

This is closer to real customer service operations than simply asking whether a business should choose an “Agent” or a “Chatbot.”

Udesk’s current product portfolio includes AI Chatbot, Omnichannel, Ticketing, AI Knowledge Base, and Agent Copilot capabilities. Businesses can start with their actual customer service tasks and then determine whether they need automated answers, workflow automation, agent assistance, or a combination of these capabilities.
