An AI chatbot is a software program that uses artificial intelligence (AI) and natural language processing (NLP) to simulate conversations with users. It can answer questions, provide recommendations, automate tasks, and even engage in meaningful dialogues.

AI chatbots process user input using NLP, analyze the context, and generate responses based on pre-trained models or rule-based algorithms. More advanced chatbots, like ChatGPT, use deep learning to generate human-like responses.

Chatbots are widely used in customer support, healthcare, education, finance, and entertainment. They help businesses automate tasks, provide instant responses, and improve user engagement.

Some popular platforms for chatbot development include:

- OpenAI’s ChatGPT API – AI-powered conversational chatbot
- Google Dialogflow – NLP-based chatbot development
- Microsoft Bot Framework – Scalable chatbot solutions
- IBM Watson Assistant – AI chatbot for businesses

AI chatbots improve customer service by providing instant replies, reducing operational costs, automating repetitive tasks, and increasing efficiency. They also enhance user experience and engagement.
