Types of Chatbots

Rule-based Chatbots

Follow predefined rules and decision trees. Limited but reliable for simple FAQ bots.

AI-Powered Chatbots

Use NLP and machine learning to understand user intent. Much more flexible and natural.

Hybrid Chatbots

Combine rule-based flows for common queries with AI fallback for complex questions.

Platforms and Tools

• OpenAI API (GPT-4): Most powerful, requires API integration
• Google Dialogflow: Enterprise-grade, good NLP
• Retool: Easy to build internal chatbots
• Custom (Rasa, Botpress): Full control, self-hosted

// Example using OpenAI API
const response = await openai.chat.completions.create({
  model: "gpt-4",
  messages: [
    { role: "system", content: "You are a helpful customer support agent." },
    { role: "user", content: userMessage }
  ]
});

Use Cases

• Customer support automation
• Lead generation and qualification
• Internal HR/IT helpdesk
