Build a beautiful-looking GPT Chatbot with Plotly Dash

ChatGPT has impressively demonstrated the potential of AI chatbots. In the next few years, such AI chatbots will revolutionise many areas of the economy. Frameworks like LangChain make chatbot development accessible to everyone. But with these frameworks, you only develop the logic of the AI chatbot. The user interface is missing. A web interface is an elegant way to make a chatbot available for everyone.

But how do you create a custom web-based interface? Answering this question is the core of this tutorial.

Here’s a demo of the final GPT chatbot app.

Why Plotly Dash?

Dash is written on top of Plotly.js, Flask and React.js. The open-source framework is licensed under the permissive MIT license. With Plotly Dash, you can build and deploy web apps with customised User Interface (UI) in pure Python. The framework abstracts the protocols and technologies needed to create a full-stack web app. This approach allows you to create data apps in a few minutes. From our point of view, Plotly Dash is the best choice to build web apps with Python.
