What is an AI Chatbot? 

AI chatbots are advanced software systems that can comprehend, analyze, and reply to human conversations in a border context. These systems use AI algorithms, such as machine learning and natural language processing (NLP), to replicate human-like conversations. They are trained on massive datasets and understand the tone for future learning. 

AI chatbots help organizations create a personalized user experience for each customer. Instead of asking users to choose from pre-defined options, these AI tools can answer conversations out of the script—usually in normal chats. 

Here are some useful purposes of AI chatbots for businesses:

• Helping in internal business workflows, including knowledge sharing and employee onboarding. 
• Offering 24x7 personalized customer support. 
• Providing recommendations based on user’s specific preferences and past interactions. 

What are the Different Types of Chatbots?

Developing a chatbot isn’t as easy as it seems; the first thing you need to focus on is choosing the right type of chatbot. So, to help you avoid any confusion, we have categorized different chatbots based on technology. So, here are the three primary types of chatbots. 

• Traditional (Rule-, menu-, and keyword-based)
• AI-powered (Contextual and Generative)
• Hybrid (Use both types of technologies)

Let’s briefly discuss each type of chatbot so you better know which one to invest in. 

#1. Traditional Chatbots

Menu-based Chatbots

Menu-based chatbots, often called button-based chatbots, are the most common and outdated. They have predefined buttons or options for users to interact with. These bots don’t use AI technologies and usually rely on customers clicking on specific options to continue the chat. This is the simplest interaction type as it doesn’t require a chatbot to understand or interpret natural language. 

Rule-based Chatbots

These bots generally operate on a set of rules and if-then scenarios. If condition A occurs, the B result is provided. These chatbots are more advanced than menu-based ones but aren’t as superior as AI chatbots. 

Keyword recognition-based chatbots

Keyword-based bots reply to user’s input by searching for specific keywords to give a reply. They can’t understand the context and the natural flow of conversation. These bots can handle some simple queries that include the keywords they understand. 

#2. AI-powered chatbots 

Finally, we have advanced bots that use AI, specifically machine learning and NLP, to understand what users mean and want. The more these bots interact, the better they get at responding.

Unlike the older chatbots we mentioned before, these AI-driven bots can handle more complex conversations and customer service tasks. Instead of giving a standard reply, the chatbot might ask a follow-up question.

As you can see, these chatbots can continue the conversation and ask for more details to ensure they provide the exact information users need. 

Voice-based chatbots

Voice chatbots are software programs that use speech recognition technology to understand spoken commands and questions. This technology changes spoken words into text. The words are then converted into numerical values or vectors that the system can understand, as these systems don't process spoken language directly as humans do.

After this processing, the chatbot uses text-to-speech technology to turn the text response back into spoken words. Voice assistants primarily use artificial intelligence to provide relevant information.

Generative AI chatbots

These are the most advanced AI chatbots. They create new responses from scratch instead of picking from pre-set answers.

Generative AI chatbots use advanced deep learning models like:

• Recurrent Neural Networks (RNNs)
• Long Short-Term Memory Networks (LSTMs)
• Transformers

These models can understand and generate human-like text based on their input. Transformers are especially popular because they can process sequences of data and handle different parts of the input simultaneously.

Many generative AI chatbots you have seen or used are built using models like OpenAI's GPT (Generative Pre-trained Transformer) and Google's BERT (Bidirectional Encoder Representations from Transformers).

#3. Hybrid Chatbots

Hybrid chatbots combine the straightforwardness of rule-based systems with the advanced capabilities of AI models, allowing them to manage a variety of tasks effectively. 

Rule-based systems: These can quickly provide predefined answers to common questions.

AI-driven models: These use machine learning to understand and generate responses based on the context of the conversation.

Here's an example of how it works: 

Imagine a customer asking your chatbot, "What is the latest watch like the Apple Watch Series 10?" The rule-based part of the chatbot will list the newest models. If the customer then asks which of those models is best for daily use, the AI component will analyze their past purchases and preferences to give a personalized recommendation.

What Makes AI Chatbots Different from Traditional Chatbots?

So, what makes AI chatbots different from traditional ones? Well, it’s obviously the technology, but there are some other factors you should consider. 

Comprehension and Engagement

AI chatbots go beyond the basic, pre-programmed question-and-answer setups typical of rule-based chatbots. Thanks to natural language understanding (NLU), they can understand user intent regardless of phrasing.

NLU, a subset of Natural Language Processing (NLP), focuses on understanding the meaning behind words, not just the words themselves. For instance, if an AI chatbot is unsure about a user's query, it can ask clarifying questions or offer a list of options to better meet the user's needs.

Learning and Evolution

AI chatbots are built on machine learning algorithms, allowing them to learn from interactions and build a sophisticated response base over time.

The more users interact with the AI chatbot, the better it becomes at predicting their intentions and delivering accurate, detailed responses. This is in stark contrast to traditional chatbots, which operate on fixed algorithms and lack the ability to evolve.

Memory and Personalization

AI chatbots can remember previous interactions with users and leverage this information in future conversations. Robotic process automation (RPA) can be integrated to execute tasks directly within the chat interface. 

For instance, a restaurant chatbot might recognize a returning customer, address them by name, recall their usual order, and use stored payment and delivery details to streamline the ordering process, making it quicker and more convenient.

Generative Capabilities

Generative AI chatbots elevate AI advancements to a new level by creating high-quality responses, including text and multimedia content, based on their training. This enables them to adapt to the user's conversation style and even show empathy.

These capabilities provide an interaction experience that is remarkably human-like, far surpassing what traditional bots can offer.

How to Build an AI Chatbot from Scratch?

Now, that’s the most awaited part! While the process of building an AI chatbot differs in every software development company, we have listed down the typical steps to help you get an idea of what it generally takes. 

Step 1: Identify Your Use Case

AI chatbots can fulfill a variety of roles. To get started, it's crucial to pinpoint exactly why you need this type of software. The more specific you can be, the better.

Start by brainstorming and asking yourself questions such as:

• Are you looking to enhance your customer support team or fully automate it?
• Do you want to use conversational AI to boost sales for your e-commerce store?
• What will be the primary function of your AI chatbot?

These questions will help you gain clarity and direction for your chatbot development strategy. In some cases, businesses require an AI chatbot that goes beyond answering simple FAQs. 

Step 2: Choose the Right Channel for Your AI Chatbot

When developing an AI chatbot, it's crucial to decide where it will be most accessible for your users. Here are some popular options:

• Your mobile app
• Your website
• Popular messaging platforms like WhatsApp, Telegram, or Facebook Messenger

If you're unsure about which channel to choose, consider the following factors:

• Accessibility: Opt for channels that your audience frequently uses. This ensures that they can easily start interacting with your chatbot.
• Ease of Integration: Platforms like your website or mobile app are often central points for customer interactions. Since users already visit them for inquiries or support, these are ideal places to launch your chatbot.

Step 3: Select the Right Tech Stack for Your AI Chatbot

After determining the type of interactions and the insights from the previous steps, it's time to choose the appropriate technologies for your AI chatbot.

To create a simple question-and-answer chatbot, you can opt for commercial solutions from AWS, IBM, or Microsoft. These platforms offer customizable chatbots that are easy to set up and can be deployed across various channels, such as websites, social media, or standalone apps.

For a more sophisticated AI chatbot with unique capabilities beyond standard engines, you might need to integrate multiple systems used in your business operations or require advanced analytics. In such cases, leveraging Python machine-learning libraries and frameworks will be essential to meet these complex requirements.

Step 4: Create a Knowledge Base for Your Chatbot

You can skip this step if you're working on a simple, rule-based chatbot. However, since you're interested in building an AI chatbot, you will need to gather data for training and learning to make it intelligent. You need to create a knowledge base that allows for continuous improvement in the context it was designed for.

Your AI chatbot's knowledge base should be filled with a substantial amount of high-quality, relevant data. Here's where you can find this information:

• Internal Data: Start with the data you already have. This could include FAQs, product manuals, customer service transcripts, or data from your CRM system.
• Public Datasets: If you're building an AI chatbot from scratch and don't have existing data, public datasets are a great option. There are many online resources where you can find datasets specific to various industries and functions.
• Generated Data: Sometimes, the best way to ensure your chatbot understands your specific needs is to create custom data. You can write multiple variations of potential customer queries, even if they lead to the same answer.

Step 5: Creating the Chatbot Conversation

Now, it's time to design the conversation flow for your chatbot. If creating a straightforward chatbot, set up a decision tree with actions and messages that users will interact with. Think of a decision tree as a flowchart; it outlines all the potential responses your chatbot can provide based on user inputs. However, you must train your chatbot to understand user intent to make it more proactive.

To develop a chatbot that can generate human-like responses, you'll need to choose a foundational model (such as GPT, BERT, or T5) and create prompts to elicit the desired responses. This process is known as prompt engineering, where scenario-based triggers are designed to teach the chatbot how to respond in various situations. The model then learns from these expected outcomes and retains the knowledge for future interactions.

Step 6: Integrate and Test Your Chatbot

The next crucial step is to integrate and test your chatbot to ensure it functions seamlessly with the product it was designed for. This involves creating an intuitive UI/UX flow that allows the chatbot to blend effortlessly into a new or existing app.

Imagine you're building your AI chatbot using the advanced language processing capabilities of the GPT-4 model by OpenAI. It's essential to design a user-friendly and intuitive interface that enables users to interact with the chatbot easily without feeling overwhelmed by the technology.

Here's how you can approach this:

Integration with Existing Infrastructure:

• API Integration: Connect your chatbot with existing systems through APIs to ensure smooth data exchange.
• Data Synchronization: Ensure that data is consistently updated and synchronized across all platforms.
• User Interface Integration: Seamlessly incorporate the chatbot into the app's user interface for a cohesive experience.
• Design Consistency: Maintain a consistent design language throughout the app to provide a unified user experience.

Testing and Validation

• Performance Testing: Evaluate the chatbot's performance under various conditions to ensure it meets the required standards.
• Deployment: Deploy the chatbot in a controlled environment to monitor its behavior and gather feedback.
• Pilot Program: Run a pilot program with a select group of users to identify any issues and gather insights for improvement.
• Refinement: Continuously refine the chatbot based on user feedback and performance metrics to enhance its functionality and user experience.

Step 7: Deploy and Supervise Your AI Chatbot

Once you're confident in your AI chatbot's capabilities, it's time to introduce it to the public. However, this is just the beginning of your journey.

Continuous Improvement and Updates

Refresh the chatbot's training data regularly with new information and user interactions. It's crucial to fine-tune the model with updated prompts and responses as new customer service challenges emerge. With these updates, your chatbot may become updated and maintain its effectiveness.

Monitoring and Analytics

Implement monitoring tools to evaluate the chatbot's performance over time. Track key metrics such as response time, resolution rate, and user satisfaction to measure its success. Monitoring allows you to identify and address any performance issues quickly.
