What is a Chatbot UI? 

The idea of the chatbot interface is to augment computer code generated by the program with graphical and language elements that human beings can perceive. Simply put, the chatbot UI is the program's part that users can see and interact with. It includes menus, texts, response buttons, contact forms, avatars, icons, animations, and more.

What's the Difference Between UI and UX?

The ‘user interface’ (UI) focuses more on the product's visual representation and emotional impact. The ‘user experience’ UX refers mainly to how users perceive the chatbot's functionality, such as its AI core

Chatbot UI UX design is an interconnected system. For example, the way a big blue button looks is the UI domain. But what happens when you press it and whether it feels good or not is in the UX domain.

Chatbot UI Best Practices 

Your chatbot may have different purposes. You might want to shorten a response time or give your clients a taste of the carrying community. The following chatbot UI best practices will help you in most cases. 

  • Choose a catchy name to evoke curiosity.

  • Create a well-considered script. This is the most time-consuming and the most vital part of chatbot UI.

  • Pump your bot with helpful data about who you are, your product or service providers, FAQs, and common concerns. 

  • Use visual effects such as strong colors, background videos, or a charming animated welcome screen.

  • Add customization features like changing the text color of the users’ message.   

How to Customize Chatbot Interface

Usually, a chatbot is implemented into a website or a company's mobile app. It should visually reassemble the brand color scheme, logos, and tone of voice. This makes customization a must.  

Chatbot builders like Tidio allow you to change almost everything in your chatbot appearance and behavior. Unless you want to program a unique decision tree or a complex contextual algorithm, pre-defined templates provide a sufficient level of customization.    

Principles of Chatbot UI design

The chatbot interface will vary depending on the type of algorithm. Menu-based chatbots will propose reply options in the form of buttons. Linguistic-based or rule-based chatbots will look like a good old chat window, although these programs are more costly than ones with button options. 

Still, the main rules of UI design apply to all chatbot types. A quality chatbot UI should be:

  • easy to understand and use 

  • visually pleasant

  • enjoyable and engaging

  • customizable
