What is Chatbot UI?

Chatbot UI is an open-source web application that provides a modern, user-friendly interface for interacting with ChatGPT and other large language models. Built as a Progressive Web App (PWA), it offers a simplify alternative to the official ChatGPT interface with customizable features and the ability to self-host. The tool is designed for developers, researchers, and everyday users who want more control over their AI interactions and prefer open-source solutions. With its clean design and responsive layout, Chatbot UI enables smooth conversations across devices while maintaining chat history and supporting various configuration options. Being open-source, it allows technical users to deploy their own instances, integrate with different API providers, and customise the experience to their specific needs.
