How to make your own chatbot from scratch

Chatbots have become indispensable tools for businesses and individuals. From improving customer support to enhancing user engagement, chatbots can help you streamline processes and foster better connections. But how do you go about making your own? 

This comprehensive guide will walk you through the steps needed to build a chatbot, from scratch, explain why you might want to, and introduce you to different platforms to help you get started.

What Is a Chatbot?

A chatbot is AI software that can simulate a conversation with a user in natural language via messaging apps, websites, mobile apps, or phones. These bots can handle a variety of tasks, from answering simple customer queries to guiding users through complex processes.

Put simply, chatbots use AI technologies—like Machine Learning (ML), Natural Language Processing (NLP), and Deep Learning—so the bot can understand and interpret human language and deliver appropriate responses.

Types of Chatbots:

‍

1. Rule-Based Chatbots: These bots follow predefined rules and use "if/then" logic to guide users through a conversation. They are simple and work well for basic interactions.
   
2. AI Chatbots: These chatbots are powered by NLP and ML and can, therefore, handle more complex tasks than rule-based bots. They can understand the context of a conversation, learn from a user’s interactions, and improve themselves, over time.
   
3. Hybrid Chatbots: These bots are a combination of rule-based and AI-powered bots, as they often start with predefined responses, but can then shift to an AI-based conversation flow if needed.

Why You Would Want to Make Your Own Chatbot

Before you dive into chatbot development, it’s essential to understand why making your own chatbot can be beneficial. The motivation behind creating a chatbot may differ depending on your specific business needs or your own personal goals.

1. Customer Support Automation

One of the most popular use cases for chatbots is automating customer service. Businesses can create chatbots that handle common customer inquiries, improving response times and reducing the workload for human support agents. An example of a chatbot in customer service is the Amtrak "Julie" chatbot, which answers travel-related questions for users.

2. Lead Generation and Sales

Chatbots can serve as a powerful tool in lead generation and sales. They can engage with website visitors, answer questions about products, and guide potential customers through the sales funnel. H&M's chatbot is an example of a sales-focused bot that helps users find outfits based on their preferences.

3. Content Delivery and User Engagement

Creating a chatbot for content delivery can boost user engagement. For instance, a media company could develop a chatbot to provide personalized news updates, quizzes, or content recommendations based on the user's interests.

4. Task Automation

Chatbots can automate repetitive tasks like scheduling appointments, answering FAQs, or sending reminders. For instance, Slack’s Slackbot automates simple tasks like sending reminders and answering common team queries.

What Types of Chatbots Can You Make from Scratch?

When you decide to build a chatbot from scratch, there are several types of bots you can build, depending on your objectives and the complexity of the tasks you want it to complete. Let's look at some real-life examples:

1. Customer Service Chatbots

These bots are designed to help customers by answering common questions and resolving simple issues.
Example: KLM Airlines’ bot provides flight information and sends boarding passes via Facebook Messenger.

2. E-commerce Bots

E-commerce chatbots help customers find products, suggest alternatives, and complete purchases.
Example: Sephora’s Virtual Assistant provides product recommendations based on customer queries.

3. Educational Chatbots

Educational chatbots help students by providing learning materials, answering questions, and offering personalized tutoring.
Example: Duolingo's chatbot helps users practice languages through interactive conversations.

4. Entertainment Chatbots

Entertainment bots engage users by providing fun and interactive content.
Example: Woebot, is a chatbot that offers mental health support and daily mood tracking in fun, interactive ways.
