A chatbot is a computer program designed to simulate a conversation with a human user. They are commonly used in online customer service to provide quick and efficient responses to common questions. Chatbots are also used in marketing and sales to qualify leads and provide information about products and services.

Some chatbots use sophisticated natural language processing systems, but many simpler ones scan for keywords within the input, then pull a reply with the most matching keywords, or the most similar wording pattern, from a database. The chatbot interacts with customers or clients in a natural, human-like way, providing them with information or performing tasks on their behalf.

Example

A chatbot can collect information from potential customers, such as their names, email addresses, and phone numbers. For instance, Drift is a chatbot tool that can be used to book appointments, schedule reminders, and more.
