What are the four types of chatbots?

The four main types of chatbots are:

1. Rule-based chatbots

Follow predefined decision trees and scripts. Each user action triggers a mapped response. Best for fixed workflows like forms and FAQ routing.

2. AI-powered chatbots

Use machine learning and natural language processing to understand intent and generate responses dynamically. Handle complex, open-ended conversations.

3. Hybrid chatbots

Combine rules for structured tasks with AI for complex queries. Start with a decision tree and escalate to AI when users ask unexpected questions.

4. RAG chatbots

Use Retrieval-Augmented Generation to answer from custom knowledge bases. They retrieve relevant documents and use AI to generate accurate, context-aware answers grounded in your verified data.
