What is an AI Chatbot?

An AI chatbot is a software app that uses Artificial Intelligence (AI) to ensure human-like conversation. It also employs technologies such as Machine Learning (ML) and Natural Language Processing (NLP) to understand, interpret, and respond to user inputs in real-time.

An AI bot can handle tasks ranging from answering customer queries to offering support and automating processes such as data collection and scheduling. It improves over time by analyzing interaction data, enhancing its accuracy and contextual understanding.

How to build an AI Chatbot [Step-By-Step Process]

To create an AI chatbot, you need to go through different steps—each serving a unique purpose. Let’s explore these steps in detail.

1. Know Your Use Cases

Since AI chatbots cater to different purposes, it’s important to know why you need it. You need to be as specific as possible while defining your core purpose. Whether you wish to make your customer support team more efficient or automate the entire process, you need to be clear.

You need to ask yourself: Do you need virtual assistants to boost your business’s sales? It’s advisable to also be specific about the main features of your chatbots. Asking such questions will give you more clarity and proper guidance for your intelligent chatbot development strategy.

Quite often, businesses look for Conversational Agent to understand customers’ behaviors, likes, dislikes, etc. These are essential to drive sales. If you also need the same, you can make an AI chatbot integrated with cutting-edge technologies.

2. Decide Where to Place

The next crucial step is to decide where to install your virtual assistant software so that customers can easily find it and use it to resolve their queries. Of course, you can select your website or mobile app to install the chatbot.

In case you are not able to decide, you can consider the following important factors;

• It’s necessary to select channels where your audiences are active on a daily basis. When you install your interactive agents on the selected channel, it makes it convenient for your customers to interact with your chatbot.
• If you are interested, you can install your chatbot on multi-channels as well. It’s a good option for medium or large-sized businesses that serve customers across the globe from multiple regions. It’s also advisable to modify the style of your chatbot to ensure it matches properly with every channel.

3. Choose the Right Tech Stack

The selection of the right tech stack depends on the type and purpose of the interactive agent. For instance, if you are keen to create an AI chatbot simply for questions and answers, you can opt for IBM, AWS, Microsoft, and others to customize any commercial chatbot. Moreover, if you seek to build a custom AI chatbot with immense capabilities that are not offered by any standard virtual assistant, you can leverage Python machine-learning frameworks and libraries.

Apart from this, the following are other tech stacks you can leverage to make an AI chatbot:

• Natural Language Processing (NLP): It lets chatbots get the ability to understand and write sentences just like an individual does. It also offers linguistic capabilities like part-of-speech tagging, tokenization, lemmatization, etc.
• Cloud Infrastructure: It lets you manage, deploy, and implement your machine learning workload, NLP engine, and chatbot solutions. It removes the dependency of your virtual assistant from the human support team.

It’s necessary to train your chatbot to give it the ability to understand the user’s intent.

To create a chatbot with the capability of creating human-like responses, you can choose a base model and develop prompts to generate the desired response. This process is popular as ‘prompt engineering’. Scenario-based prompt triggers are essential to train chatbots on how to respond in different situations. This model learns from the expected outcomes and retains it for subsequent usage.

5. Integrate and Test the Chatbot

Now, it’s time to integrate the desired functionalities into the chatbot. Make sure you integrate a simple yet intuitive UI/UX flow to make the virtual assistant work seamlessly with existing or the latest software.

For instance, when you build an AI chatbot, you need to ensure it has a user-friendly interface. It lets users interact conveniently without any hindrance. You need to also perform API integration, data synchronization, user interface integration, etc.

Testing and validation are equally important to ensure the developed virtual agent performs as per expectations. For better results, you can perform two important types of testing, including functional and performance testing.

6. Launch

Once you are satisfied with everything, you can finally launch your AI chatbot for your target users. Even after the launch, you should put continuous effort into its maintenance. Make sure you update it regularly based on the latest trends, user feedback, etc. You can leverage many monitoring tools to gain relevant insights.
