A chatbot is a service, powered by rules and sometimes artificial intelligence, that you interact with via a chat interface. The service could be any number of things, ranging from functional to fun, and it could live in any major chat product. A chatbot is a computer program that simulates human conversation through voice commands or text chats or both. Chatbot, short for chatterbot, is having an AI feature that can be embedded and used through any major messaging applications. For example, Facebook Messenger, Slack, Telegram, Text Messages, etc.

A chatbot builder, or a chatbot development platform, is an application through which one can construct a chatbot for the web, their app or for popular messaging platforms. A chatbot publishing platform on the other hand, is the channel through which the chatbot can be accessed by users. We cannot build a bot without Artificial Intelligence. We need machine learning to make the bot adapt to the information and examples. Then we need to test the capacity of the bot in the real world that would deduce certain probabilities on of which can be chosen. But only chatbot can be built with the AI.


A chatbot is sometimes referred to as a chatterbot, is programming that simulates the conversation of a human being through text or voice interactions. Chatbot virtual assistants are increasingly being used to handle simple, look-up tasks in both business-to-consumer (B2C) and business-to-business (B2B) environments. It also allows companies to provide a level of customer service during hours when agents are not available. Chatbots can have varying levels of complexity and can be stateless or stateful. A stateless chatbot approaches each conversation as if it was interacting with a new user. Chatbot allows developers to build conversational user interfaces for third-party business applications.

Most important aspect of implementing a chatbot is selecting the right natural language processing (NLP) engine. If the user interacts with the bot through voice, for example, then the chatbot requires a speech recognition engine. Chatbots built for structured conversations are highly scripted, which simplifies programming but restricts the kinds of things that the users can ask.

Business-to-business environments, the chatbots are commonly scripted & used to respond to frequently asked questions or perform simple, repetitive calls to action. In sales, for example, a chatbot may be a quick way for sales reps to get phone numbers. Chatbots can also be used in service departments, assisting service agents in answering repetitive requests. Generally, once a conversation gets too complex for a chatbot, the call or text window will be transferred to a human service agent.

Working of Chatbots:

They are built on AI technologies, including deep learning, natural language processing and machine learning algorithms, and require massive amounts of data.

The chatbots are important because, the time savings and efficiency derived from AI chatbots conversing & answering re-occurring questions is attractive to companies looking to increase sales or service productivity. As consumers continue to move away from traditional forms of communication, chat-based communication methods are expected to rise. Chatbot-based virtual assistants are increasingly used to handle simple tasks, freeing human agents to focus on higher-profile service or sales cases.

Examples of Chatbots:

  • Weather bot: Get the weather whenever you ask.
  • Grocery bot: Help me pick out and order groceries for the week.
  • News bot: Ask it to tell you when ever something interesting happens.
  • Life advice bot: It will tell problems and it helps to think of solutions.
  • Personal finance bot: It helps to manage people’s money better.
  • Scheduling bot: Get a meeting with someone on the Messenger team at Facebook.
  • A bot that’s your friend: In China there is a bot called Xiaoice, built by Microsoft, that over 20 million people talk to.
