Chatbot is software that can simulate and process conversations (written or spoken) with a user in natural-like language. Chatbots can be used in mobile applications, messaging apps, websites, social media, etc. The interaction with a chatbot is similar to communication with a real person.

Before we move on to the tech part explaining how to make a chatbot, take a look at the key benefits that a business can get thanks to chatbot implementation:

  • Better customer experience – customers expect to get support 24/7, otherwise they get disappointed and are less likely to turn into loyal customers. Implementation of a chatbot solution will allow to provide high-quality customer service no matter the time or day. As a result, it leads to a better customer experience thanks to the timely support that customers get.
  • Faster purchase process – modern chatbots can provide answers to customer’s questions and even sell products right inside the conversation. For example, if a customer is looking for a product, a chatbot can provide them with all the necessary information and offer the solution right away. Therefore, customers make purchasing decisions faster.
  • Personalized services – chatbots can be used for a number of tasks and provide personalized services. During the customer lifecycle, they can offer them useful information about products, provide customer support, and help customers solve any problems they encounter.
  • Reduced costs of customer support – chatbots can answer the most frequently asked questions, reducing the load on the customer support services. As a result, they reduce operational costs and the load on customer support officers.
  • Customer data mining – you can view chatbots from the data mining point of view. You can analyze what information customers seek the most and improve your services accordingly.
  • Back-end operation optimization – bots can be used for a number of reasons. For example, JP Morgan implemented a bot that reviewed loan contracts and saved over 360,000 hours spent on manual review of contracts by lawyers. The company also uses chatbots that help employees to reset passwords or that provide access to the software.

How to Build a Chatbot from Scratch: Types & How They Differ

It’s impossible to build a chatbot from scratch without knowing their main types and how they differ. This section of the article explains what AI chatbot development is and how it can benefit your business.

Rule-Based Chatbots

Rule-based chatbots are the most basic solutions used for answering simple questions. Users interact with such bots by clicking on predefined questions that lead to the desired answer. The chatbot provides answers from the decision tree.

If you want an example, take a look at Facebook Messenger. The platform allows businesses to perform automated customer support by providing buttons with possible inquires and automatically providing answers.

While such chatbots are comparatively easy to build, they are prone to providing wrong answers and are quite limited in functionality. In some cases, they can frustrate customers by providing wrong answers.


You can see how rule-based chatbots work in the image below.

AI-Based Chatbots

AI-based chatbots are also called conversational chatbots or natural-processing chatbots. Such bots rely on Artificial Intelligence chatbot algorithms and machine learning to process user inputs and provide highly personalized answers relevant to the content.

Interaction with AI-based chatbots happens by writing questions in the human language. The bot is able to identify different questions written by a human.

After a user types in a question, the bot identifies the user’s intent, asks additional questions if needed, and provides answers using the dialogue tree to specify what problems a user has and how they can be addressed.

Which Chatbot Type to Choose for Your Business

You are probably wondering which type of chatbots to use for your business. The answer fully depends on your business needs and objectives.

Rule-based chatbots are usually used for two purposes:

  • to collect contact details to set a call or a meeting later
  • to provide basic customer support

AI-based chatbots are more advanced in terms of functionality. They can be used to perform the following tasks:

  • handle simple requests
  • process natural language (NLP)
  • provide personalized answers
  • confirm user intent
  • execute transactions on the behalf of customers
  • keep conversations natural
  • form sentences by itself

 How to Make a Chatbot from Scratch: Process Overview

In this part, you will learn how to make a chatbot step-by-step. This guide will help you do everything right and avoid costly mistakes for business.

Let’s investigate the key processes involved in custom chatbot development and steps to build a chatbot.

Step 1: Identify Customer Needs and Expectations

The main goal to make a chatbot from scratch is to improve user experience. At this stage, you need to identify customer expectations and align them with business 

The analysis of customer needs will help you come up with a list of possible features for your future chatbot. For example, you have a restaurant application, your users might be interested in knowing available reservation time.

Step 2: Find a Chatbot Development Company

This step is probably the most important in the whole journey. You need to find a company that knows how to make an AI chatbot and has previous relevant experience. The below action plan will help you make the right choice and choose the best chatbot development company that will be able to create a highly customized solution for you.

Here is what you will need to do:

  • Identify prospects

Start with finding professionals providing chatbot development services. While it’s possible to hire freelancers for the job, consider the option of working with a professional software development company. Cooperation with a company involves fewer risks since the company won’t disappear into the waters without delivering your chatbot. Outsource companies also have multiple specialists who can be of use for your project. You can always use such platforms as Clutch, TopDevelopers, ITFirms, etc. to find prospects there.

Places to Find a Chatbot Development Company
  • Check the portfolio

The portfolio of the company might not include a chatbot, since such solutions are often developed as a part of a bigger project – an app, for example. As a starting point, you can single out the companies that have previous experience with mobile app development, artificial intelligence, and machine learning – technologies used to build a chatbot from scratch.

  • Check reviews

Such platforms as Clutch provide reviews of the companies. You can check them on the platform or take the investigation a step further and reach out to the existing clients of your prospect to get their review straight from the source.

  • Get in touch with prospects

Reach out to the selected companies to talk about their experience, provided services, cooperation model, etc. consider the geographical region and any cultural difference that might interfere with your cooperation.

  • Ask the right questions

Learn about the services the company provides, how they can help you with chatbot creation, whether they have previous experience with natural language processing and how they usually work on projects as your own one.

As a result of this step, you need to have a company that will create a chatbot for you.

Step 3: Choose Features and Technology for Your Chatbot

If you want to know how to make a chatbot that will improve user experience, start with identifying the features that can help them move forward in their customer journey. Below, you can find a list of some key features that you need to consider:

  • Seamless cross-channel communication

If your company is active across different platforms like an app, a website, social media, you need to provide a seamless and unified user experience across all of them.

  • Rich messaging

Your chatbot needs to support different types of content. Aside from answering with plain text, it needs to have the functionality to share links, useful articles, or even to help find products.

  • Integration with third-party systems

You can integrate the chatbot with a number of third-party solutions and systems such as CRM, accounting systems, marketing analytics, payment gateways, etc.

Possible Integrations for a Chatbot
  • Human handoff

In some cases, even the smartest AI chatbots can’t help users with an issue or question. Such scenarios need to include the automatic handoff of the conversation to your employees.

  • Accessibility

Modern systems allow building highly accessible chatbot solutions with the support of voice messaging, zoom in, support for screen readers, etc.

  • Security

Depending on the industry you operate in, a chatbot needs to meet the security standards and such regulations as HIPAA, PCI, etc.

  • Advanced analytics

Chatbots generate a lot of data that you need to be able to analyze. It can be either integrated with one of the third-party analytics systems via API or has built-in analytics tools.

Step 4: Design the Conversation Flow

A professional development company will know how to make a chatbot and design the conversation flow. While using chatbot building platforms, you are limited in the choice of possible conversation formats. You can only choose, drag and drop ready-to-use blocks with answers.

When you will be working on chatbot script creation, you need to keep it close to the topic and the purpose of the chatbot. You should aim for conversation flows that will allow customers to communicate naturally with your chatbot.

Step 5: Train Your AI-Based Chatbot

This step is only necessary if you decide to build a chatbot AI project. Before you launch it, you need to train it on a massive data set, such as support tickets, email, etc. You can also get a third-party data set with the information that your chatbot needs to know. If you work with a software development vendor, it will take on this part of the process on and you won’t need to worry about it.

Step 6: Test a Chatbot

Before you launch the chatbot, you might want to test it with a few users to see how they’ll interact with it and how it will meet their intent. Chatbot testing differs from classic software testing since here you need to foresee even the most unpredictable scenarios and specify how the chatbot will react to them, for example when users ask questions not related to your business.

Step 7: Deploy and Maintain

The work on chatbot doesn’t end with its deployment. You can use the collected information and statistical data to refine answers and conversational flows to make your chatbot even more useful for customers.

How to Make a Chatbot: Final Thoughts

The development of a chatbot is not a simple process that requires the understanding of modern technologies and how to align them with business requirements.
