What Is an AI Chatbot? The Complete Guide for 2025
AI chatbots are the new standard for customer service. Discover how they work, what they cost, and why 67% of consumers prefer chatting with a bot over waiting on hold.
What is an AI chatbot?
An AI chatbot is an automated conversational agent that uses artificial intelligence to have natural conversations with visitors on your website, in your app, or via messaging platforms like WhatsApp and Facebook Messenger.
Unlike old-school chatbots that can only respond to pre-programmed questions, modern AI chatbots understand intent and context. They can:
- Understand natural language (even with typos)
- Answer contextual follow-up questions
- Learn from previous conversations
- Execute complex tasks (bookings, orders)
- Seamlessly hand over to a human when needed
According to Gartner, by 2027 more than 25% of all customer service interactions will be fully handled by AI - without human intervention.
How does an AI chatbot work?
Modern AI chatbots combine multiple technologies to have natural conversations:
Natural Language Processing (NLP)
The chatbot analyzes the user's text to understand intent. "I want to cancel my order" and "cancel order please" are recognized as the same request.
Large Language Models (LLM)
AI models like GPT-4 generate natural, human-like responses. They understand nuance, humor, and can even provide complex explanations.
Knowledge Base & RAG
The chatbot searches your documentation, FAQs, and products to provide accurate information. This is called Retrieval-Augmented Generation (RAG).
Integrations & Actions
Through API connections, the chatbot can execute actions: place orders, schedule appointments, create tickets in your CRM.
