A chatbot is a software application designed to simulate human-like conversations using text or voice. It interacts with users through messaging apps, websites, or voice assistants, providing automated responses based on predefined rules or artificial intelligence (AI).

Types of Chatbots:

  • 1. Rule-Based Chatbots: Follow predefined scripts and respond based on specific keywords or patterns.
  • 2. AI-Powered Chatbots: Use machine learning and natural language processing (NLP) to understand and generate human-like responses.
  • 3. Hybrid Chatbots: Combine rule-based logic with AI for more flexible interactions.
