Chatbot's services could range from a number of things from functional services to fun. Some examples of chatbots can be found in major products like Facebook Messenger, Slack, and Telegram. While some chatbots are designed with sophisticated natural language processing systems, most of the widely adopted chatbots scan and identify keywords within the input and pull a reply with the most matching keyword from its database. Chatbots developed with the most sophisticated algorithms use machine learning techniques to improve their accuracy of their natural language processing capabilities. The end-users' interaction with the chatbot helps it to leverage deep learning programming evolution and better predicts the responses while communicating with the end user.

Artificial Intelligence involves incorporating features into machines that mimic human intelligence and cognitive attributes like self-learning, visual perception, speech recognition, logical problem solving, and decision making. The Artificial Intelligence field aims to solve human intelligence and put its features in software, robots, and machines in general for increased efficiency in performing tasks that exceed common mathematical boundaries and human capacities. It involves problem-solving skills and pattern recognition from abstract audio-visual or input data, deep learning for automatic error perfection that is'self-learning', prediction capabilities based on present datasets, and accurate simulation from raw data to name a few.
