AI chatbots aren’t an unknown concept for modern consumers. Recent research report that 96% of consumers have heard of them. The number of those who had at least one interaction with a chatbot, equals 88%. Regarding the satisfaction of solving issues via chatbots, 1 out 10 consumers pointed a negative experience. These numbers prove the importance of chatbots for the way businesses and consumers communicate. 

The chatbots have advanced from simple rule-based systems to sophisticated AI-driven pieces of software capable of interpreting and responding to complex human queries. It all began with basic scripts and decision trees, which later evolved into more advanced models made possible by Natural Language Processing (NLP) and machine learning. 

As for business today, AI chatbots are extremely valuable since they are not only capable of managing dynamic conversations but also integrating with various platforms and technologies. IBM reports that AI chatbots are responsible for 30% of the decline in customer support fees. Also, implementing a chatbot has the potential to save up to $8 billions. Taking into account these benefits, businesses may wonder how to build an AI chatbot.

In this article, we’ll delve into the nuts and bolts on how to make an AI chatbot. We’ll cover topics — from AI chatbot definition to its architecture.

An AI chatbot is software that uses artificial intelligence to have conversations with people, similar to how a human would. It uses natural language processing (NLP) and machine learning to understand what users say, figure out what they mean, and respond appropriately. Because of this, AI chatbots can handle about 80% of routine queries on their own. 

One of the primary features that makes AI chatbot stand apart from traditional scripted bots is generative AI dynamic conversation. It means that AI chatbots can generate responses dynamically, adapting to the context and flow of the conversation. It gives a feeling of a human-like chat and builds up user engagement.

Also, AI chatbots can be used to provide omnichannel messaging support, e.g. they can operate on multiple platforms, such as websites, mobile apps, and social media. Regardless of communication channels, users get an equally seamless user experience.

Usually, AI chatbots are designed to guide users towards specific goals, such as completing a purchase or resolving an issue, through a series of targeted questions and prompts. To achieve this purpose, chatbots come with goal-based conversations. 

However, when there’s an issue that cannot be resolved by a chatbot, seamless human agent handover & agent co-pilot features helps to cut down long waiting-times. Chatbot can quickly hand the conversation over to a human support agent, who can take over without losing the context. Additionally, chatbots can assist human agents by suggesting responses, making interactions more efficient.

When it comes to tailored responses, this feature is made possible thanks to sentiment analysis. Highly intelligent AI chatbots can analyze the sentiment behind user messages. Therefore, they can tailor responses based on the user’s mood or emotional state. This is crucial for delivering empathetic customer support, which, in turn, can increase customer satisfaction.

From the perspective of a MarTech development company, chatbot marketing capabilities might become quite handy. AI chatbots can be used to automate marketing efforts, such as sending personalized messages, promoting products, and even helping users navigate from initial interest to completing a purchase.

AI chatbots may come with built-in analytics tools that collect data on how users interact with bots and analyze it. With this information, decision-makers can better understand what users like, how they behave, and where improvements are needed. This helps them create more targeted and effective campaigns.

Also, business can strengthen their service thanks to integration via chatbot API. Integration capabilities with third-party applications and services extend the chatbot’s functionalities, such as processing payments, fetching data from external databases, or executing complex workflows.

Another not unimportant concern of modern business and consumers is data privacy and security. AI chatbots are normally built with strong security protocols to keep user data safe and private, following rules like GDPR to ensure conversations are confidential.

Lastly, to keep brand identity, businesses can customize the chatbot widget. It will make the chatbot more engaging and enrich the overall user experience.

How to create an AI chatbot that meets business goals and is convenient for users to use? To achieve this, Lightpoint Global come up with a well-planned approach, which involves several essential phases. 

The first step in building an AI chatbot is designing the user interface (UI) and user experience (UX). The chatbot’s UI/UX should be intuitive and user-friendly, so that users can interact with the bot intuitively. 

For this, it’s necessary to think over the chatbot’s persona, tone of voice, and conversational style. The design should come in keeping up with the brand’s identity and relevant to the target audience. 

On top of that, prototyping and wireframing tools can be used to visualize the chatbot’s flow and interactions before development begins.

While designers work on the design, developers’ work starts with choosing the right technology stack and platform. This step is crucial for the chatbot’s performance and scalability. The team is to decide on the appropriate NLP engine, machine learning frameworks, and backend infrastructure. 

When it comes to a platform selection, it should support the chatbot’s requirements, such as omnichannel messaging, real-time processing, and trouble-free integration with existing software. Among the common choices, there are such bot development platforms like Microsoft Bot Framework, Dialogflow, and Rasa. Each platform has its own strengths, so the best choice depends on the specific goals of a chatbot.

Once the design and technology stack are in place, the development phase takes place. This process centers around coding the chatbot’s core functionality, including intent recognition, entity extraction, and dialogue management. 

Also during this phase, training the chatbot is run, which requires a dataset of user queries and responses. The dataset should be diverse and representative of the expected interactions. Machine learning models are trained on this data to improve the chatbot’s accuracy in perceiving and answering to user inputs.

Developed versions of chatbot are put through testing, which is essential to ensure the chatbot performs as expected. Chatbots are tested through various scenarios, including edge cases, to identify any bugs or shortcomings. 

Testing should cover all aspects of the chatbot, including its conversational flow, response accuracy, and integration with external systems. User testing can also be conducted to gather feedback and make necessary adjustments before the chatbot is deployed.

After thorough testing and proof that there are no bugs, the chatbot is ready for deployment. The chatbot is integrated into the desired platforms, such as websites, mobile apps, or messaging services. 

However, the work doesn’t finish here, as one may suggest. Usually, post-deployment, continuous monitoring is set up to track the chatbot’s performance and user interactions. Analytics tools reveal how users engage with the chatbot, allowing for ongoing optimization and updates. Regular monitoring also helps in pinpointing any issues or weak points, ensuring the chatbot remains efficient.

The AI chatbot architecture supports its functionality, ensuring smooth operation and interaction with users. That’s why it must be carefully thought over and executed. Here are the key components of an AI chatbot's architecture:

The user interface (UI) is the front-end layer that users interact with. Typically, it consists of the chat window or integration points like websites, messaging apps, or voice assistants. The UI should be easy to navigate and interact with. Features like quick reply buttons, carousels (which let users swipe through options), and support for images or videos can enhance the interaction and make it more engaging.

NLP is the core component that makes it possible for chatbots to interpret what users say, break down their messages, and respond in a meaningful way. Intent recognition determines what the user wants to achieve with their message, while entity extraction pulls out specific information, such as dates or locations, from the text. Sophisticated NLP models strengthen the chatbot’s ability to handle manage more complex questions and give more accurate answers.

The backend server is where the chatbot’s logic and processing occur. It includes the chatbot engine, which manages the flow of conversation and decision-making processes. The server also handles integration with databases and external APIs, allowing the chatbot to fetch and store information, process transactions, and execute complex workflows.

Machine learning models help the chatbot get smarter over time. They are trained on vast datasets to understand how people interact. Depending on the use case, supervised learning (where the model learns from labeled data) or unsupervised learning (where the model identifies patterns without explicit labels) may be employed. As the model learns, it keeps improving, making the chatbot better at giving accurate and helpful responses.

The integration layer is what connects the chatbot with third-party services and API to add to its functionalities. Thanks to this, chatbots can perform tasks like booking appointments, processing payments, or retrieving user-specific data. Also, it contributes to handling data exchange efficiently and securely, particularly when it comes to sensitive information.

The process of building an AI chatbot is conducted throughout multiple stages: designing an intuitive UI/UX, selecting the right technology, developing and training the bot, and ensuring a reliable architecture. All of these steps are necessary for strategizing and the ideal implementation of the AI chatbots, focused on the improvement of the customers’ interactions and business performance.
