What are the different types of bots and how do they work ?

Robots, or “bots” as they are commonly called, are playing an increasingly important role. These automated computer programs are found in various fields, from managing computer systems to interacting with customers. Understanding the different types of bots and how they work is necessary for businesses and individuals who want to take advantage of this technology.

The different types of bots

Rules-based bots

These bots operate by following a set of predefined rules to respond to user inputs and actions. They are simple to set up and suitable for basic and repetitive tasks.

Machine learning bots

These bots use machine learning algorithms to analyze large amounts of data and improve their performance over time. They are more sophisticated than rule-based bots and can adapt to more complex situations.

Conversational bots

These bots use natural language processing (NLP) techniques to understand and respond to human language. They can simulate a natural conversation with users and provide a more fluid and intuitive experience. Adopt this technology and revolutionize your digital strategy with a chatbot.

Chatbots are conversational bots designed to interact with users via instant messaging platforms like Facebook Messenger, WhatsApp or WeChat. They provide a convenient and accessible communication channel for customers.

Voice bots

Voice bots use speech recognition to interact with users by voice. They are often used in virtual assistants like Siri, Alexa or Google Assistant.

Web bots

Web bots are computer programs that automate tasks on the Internet, such as searching for information, comparing prices or booking tickets.

Social media bots

Social media bots automate tasks on social networks, such as posting content, responding to comments or sending private messages.

Malicious bots

Malicious bots, also known as "malbots", are designed for malicious activities such as spam, phishing or denial of service attacks.

How bots work ?

How bots work depends on their type and complexity. However, there are some key principles that are common to most bots.

Information collection

Bots, these automated computer programs, play an important role in gathering information. They operate in different ways to gather valuable data, fuel their intelligence and their ability to interact with the digital world. This is because bots collect information from users via user interfaces, messages or external data. They can ask questions, request clarification and guide users in entering the required data.



Information processing

Bots analyze the collected information and apply rules, algorithms for machine learning models to make decisions or generate responses.

This is because when a user interacts with a chatbot, whether by entering text, clicking buttons, or using voice, the input is sent to the chatbot's system for processing.

Then, the chatbot uses natural language processing (NLU) algorithms to analyze and understand the user's text or voice. This step involves extracting the meaning and intent behind the user's messages. NLU allows the chatbot to understand requests, questions, orders, etc.

Once the chatbot understands the user's intent, it proceeds to process the request. This can involve different actions depending on the functionality of the chatbot, such as searching for information, performing specific tasks, providing recommendations, etc.

Action or communication

Bots perform actions based on the processed information, such as sending responses, completing tasks, or interacting with other systems.

Communication actions consist of sending responses to users based on their requests or interactions. These responses may be text messages, images, links, videos, or other types of multimedia content.

Chatbots use natural language generation algorithms to produce relevant and coherent responses. For example, if a user asks for information about a product, the chatbot can respond by providing a detailed description of the product along with links to relevant pages on the company's website.

In summary, chatbots not only communicate with users by providing them with answers, but they can also perform functional actions based on the processed information.


Bots offer a wide range of applications and can automate many tasks, improve efficiency and provide a more personalized user experience. Understanding the different types of bots and how they work is essential to choosing the solution best suited to your specific needs.
