What is a Chatbot? 

A Chatbot is like a digital assistant designed to chat with you just like a real person would. While not all Chatbots use Artificial Intelligence (AI), the more advanced ones rely on conversational AI techniques like Natural Language Processing (NLP). This allows them to understand your questions and respond in a way that feels natural and human-like, making interactions smoother and more engaging. 

The latest evolution? Generative AI-powered Chatbots. These next-gen bots take things to a whole new level. They don’t just answer basic questions—they can handle complex queries, adapt to your conversation style, and even respond with empathy. Imagine asking a Chatbot about your travel plans, and it not only helps book your flight but also suggests activities tailored to your preferences.

How Does a Chatbot Work? 

If you’ve ever chatted with a bot online, you might’ve wondered how they work. There are three main ways Chatbots function: rules-based, AI-powered, and live agent support. Let’s break them down: 

1) Rules-based Chatbots 

These are the simpler bots, and they work off pre-set instructions. Here’s how they do their thing: 

a) Triggered by Events: These bots react to specific actions, like when you click a button or say “yes” or “no.” 

b) Keyword Match: If you mention certain words, like saying “black” in your order, the Chatbot will recognise it and take action. But it can only recognise exact matches! 

While they’re handy for simple tasks, they can’t handle much beyond that 

2) AI-powered Chatbots 

AI bots are a bit smarter! They use Natural Language Processing (NLP) to understand your words better. Here's what makes them stand out: 

a) Understanding Intent: Instead of just looking for specific words, they try to understand the meaning behind your sentence. 

b) Learning Over Time: These bots get smarter with use, learning from their mistakes and getting better at answering your questions. 

c)  Great for Bigger Businesses: They’re ideal for places that have a lot of customers and need to handle more complex conversations. 

3) Live Agent Support Chatbots 

Sometimes, a bot needs backup from a human! Here’s how they handle that: 

a) Switching to a Real Person: If a customer needs more help, the bot will connect them to an available agent with the right expertise. 

b) Keeping You Informed: The bot will tell you who you’re chatting with, how long the wait might be, and when help is on the way. 

This smooth transition makes for a great customer experience, blending automation with human support.

Types of Chatbots 

Businesses worldwide are leveraging various types of Chatbots to enhance customer service and streamline operations. Let’s dive into the different types of Chatbots, how they’re used, and which ones might be perfect for your needs!

1) Voice Bots 

Imagine talking to a bot that feels almost human! Voice bots use AI and Natural Language Understanding (NLU) to recognise your voice, understand your request, and respond conversationally.

Common Uses: 

a) Virtual assistants like Alexa or Google Assistant 

b) Integrated into customer service tools like IVR systems for a seamless experience. 

2) Hybrid Chatbots

Why They’re Awesome: 

a) Instant responses for simple questions 

b) A human is always ready to step in when the bot reaches its limits 

3) Social Messaging Chatbots 

With social media at the centre of communication, these bots work on platforms like Facebook Messenger, WhatsApp, and Instagram. They help businesses engage with customers where they spend the most time. 

Benefits: 

a) Round-the-clock engagement without adding workload to human agents 

b) Improved customer satisfaction by meeting them on their favourite platforms.

a) Best For: 

a) Answering straightforward queries using natural language processing (NLP) 

b) Combined with menu-based navigation as a fallback option 

7) Rules-based Chatbots 

These bots work on an “if-then” logic, making them perfect for businesses that know the exact types of inquiries their customers ask. 

a) Pros: 

a) Accurate and quick responses for predefined queries 

b) Cons: 

a) Developers must program every possible query variation, or the bot won’t understand the question.
