What is a Chatbot? Definition, Types, Pros & Cons

Chatbots are becoming more and more popular in the digital world, especially for businesses that want to provide better customer service, increase sales, and improve efficiency.

But what exactly are chatbots, and how can they benefit your business? In this article, we will answer these questions and more, by giving you a comprehensive overview of chatbots, their types, pros and cons, and some real-world examples.

What is a Chatbot?

A chatbot is a software program that can simulate a conversation with a human user, using natural language processing (NLP) and artificial intelligence (AI).

A chatbot can understand the user’s input, either through text or voice, and respond accordingly, either by providing information, answering questions, performing tasks, or engaging in casual chat.

Chatbots can be integrated with various platforms, such as websites, mobile apps, messaging apps, social media, email, or phone. Chatbots can also be classified into two main categories, based on their functionality and complexity: rule-based chatbots and AI chatbots.

Types of Chatbots

1. Rule-Based Chatbots

Rule-based chatbots are the simplest and most common type of chatbots. They follow a predefined set of rules and logic, and they can only respond to specific commands or keywords.

They are not very flexible or adaptable, and they cannot handle complex or ambiguous queries. They are usually used for simple and repetitive tasks, such as booking appointments, ordering food, checking the weather, etc.

For example, a rule-based chatbot for a pizza delivery service might ask the user to choose from a list of options, such as size, crust, toppings, etc., and then confirm the order and the delivery address.

If the user asks something that is not related to the order, such as “How are you?” or “What is your favourite pizza?”, the chatbot might not be able to answer, or it might reply with a generic message, such as “Sorry, I don’t understand” or “Please stick to the topic”.

2. AI Chatbots

AI chatbots are the more advanced and sophisticated type of chatbots. They use machine learning (ML) and natural language understanding (NLU) to learn from the user’s input and feedback, and to generate more natural and human-like responses.

They can handle complex and varied queries, and they can also initiate and maintain a conversation, by asking questions, providing suggestions, or expressing emotions.

For example, an AI chatbot for a travel agency might ask the user about their preferences, budget, destination, etc., and then provide personalized recommendations, based on the user’s profile and history.

If the user asks something that is not related to the travel, such as “What is your favourite place to visit?” or “How do you cope with jet lag?”, the chatbot might be able to answer, or it might reply with a relevant or humorous message, such as “I love Paris, it’s so romantic” or “I don’t get jet lag, I’m always on the go”.

Pros and Cons of Chatbots

Chatbots have many advantages and disadvantages, depending on their type, design, and implementation. Here are some of the most common pros and cons of chatbots:
