In today’s world chatbot plays an important role in our society as it is relatively a new technology. It gives us information, entertain us and help us in lots of manners. Basically, we can define a chatbot as a program that is designed to counterfeit a smart communication on a text or spoken ground or it refers to a chatting robot (it is all about the conversation with the user; a robot answers to the questions asked by the user). It recognizes the user input as well as by using access information and pattern matching to provide a predefined acknowledgement. When the input is being given, a response from a predefined pattern from the database is given to the user in which the order of the sentence is recognized and a saved response pattern is acclimatized to the exclusive variables of the sentence. This paper addresses the design and implementation of a Chatbot System using the Whatsapp Application where it will detect and recognize the input image of the vehicle number plate and show the information of the vehicle owner as an output. It also focuses on the methodology which is being used for the extraction of characters from the vehicle number plate.
